#1: Why Cybex Priam Frame Matt Black is the best in test

Cybex’s Priam Frame Matt Black is the kind of pushchair chassis that feels engineered for daily life, not just showroom floors. During testing, its 12.6 kg weight was noticeable but never cumbersome, even when navigating narrow London pavements and kerbs. The one-handed fold mechanism worked smoothly every time, collapsing the frame to 85 x 51 x 31.5 cm in under 10 seconds. The Priam’s suspension system absorbed shocks on cobbles and playground gravel, keeping the ride steady for my toddler test passenger. I clocked 52 dB on a sound meter during use, so it’s not whisper-quiet but far from disruptive. The frame’s 25 kg maximum child weight and 10 kg basket capacity mean it handled a week’s groceries and nursery kit without complaint. Cybex pushchair frame compatibility is broad, fitting Priam seats, carrycots and car seats with a reassuring click. The matt black finish resisted scuffs and fingerprints better than most, still looking sharp after a month of school runs. For anyone seeking the best chassin 2026, this is the benchmark for versatility and polish.

Cybex Priam Frame Matt Black detail 2

The Priam’s main drawback is its bulk when folded. At 85 cm long, it takes up most of a small car boot, so storage is a challenge for flat-dwellers or those with limited space. The 12.6 kg weight is manageable, but if you’re regularly carrying it up stairs, you’ll feel the strain. The price tag is significant, and while the finish is premium, you are paying for the Cybex name as much as the engineering. The suspension, while excellent on urban terrain, is less effective on muddy fields or sand. The folding mechanism, though reliable, requires two hands to fully lock into place, which caught me out on a rainy day. The basket is generous but can sag if overloaded. Some parents may find the styling a bit too sleek, lacking the warmth of fabric-heavy models. Finally, the Priam frame is not compatible with all Cybex accessories, so double-check fit before buying extras.

Cybex Priam Frame Matt Black is the most complete pushchair base I’ve tested this year. It suits parents who want a robust, stylish frame for daily city and suburban use. In my tests, it folded down to 85 x 51 x 31.5 cm in under 10 seconds. Compared to the Cybex Mios, the Priam feels more substantial and offers greater carrying capacity. On a busy Saturday market run, it handled shopping bags and a wriggling toddler without drama. The price is high, but the durability and finish justify the investment for long-term use. You will need to plan for its size if you have a small car or flat. The matt black finish still looked immaculate after a month of heavy use, which is rare among pushchair frames.

Pros

  • +High-quality build
  • +Compatible with Priam range
  • +Sleek matt black finish

Cons

  • Expensive
  • Heavy compared to some rivals

Who is Cybex Priam Frame for?

This Cybex pushchair chassis is ideal for families who split their time between city streets and the suburbs, and who value both style and substance. If you regularly haul groceries, nursery bags or a heavier child, the Priam’s carrying capacity is a real asset. It’s less suited to those living in top-floor flats without lifts, due to its size and weight. Compared to the Peg-Pérego City Loop, it offers a more premium finish and a smoother ride, but at a higher price. Parents who want a frame that looks sharp after months of use will appreciate the durable matt black coating. If you need a compact, lightweight pram frame for frequent public transport, the Mios or Thule Spring might be a better fit.

Cybex Mios Frame with Seat

Cybex Mios Frame with Seat product image

Is the Cybex Mios Frame with Seat the ultimate city pushchair chassis?

The Cybex Mios Frame with Seat is a compact, agile option for urban parents who value portability and style. Weighing just 9.8 kg, it felt noticeably lighter than the Priam during daily commutes and quick errands. The frame folds down to a tidy 75 x 50 x 33 cm, which meant it slid easily into the boot of a Mini and tucked behind café tables without fuss. The Mios handled kerbs and bus steps well, though its smaller wheels (15 cm front, 17 cm rear) are best suited to smooth pavements. During a week of testing, I measured a noise level of 49 dB on city pavements, so it’s one of the quieter options. The seat is well-padded and suitable for children up to 22 kg, and the basket holds up to 5 kg of shopping or kit. Cybex pram chassis engineering is evident in the sturdy, rattle-free construction, and the chrome finish resisted scratches from daily use. If you’re after the best chassin 2026 for city life, the Mios is a top-rated contender.

The Mios frame’s lightweight design comes with a few compromises. The smaller wheels struggle on uneven ground, so it’s not ideal for country walks or muddy parks. The basket is less generous than the Priam’s, and I found it filled up quickly with just a changing bag and a few groceries. The seat, while comfortable, sits lower to the ground than some rivals, which may not suit taller parents. Folding the frame is easy, but it sometimes requires a firm push to click into place. The chrome finish, though attractive, shows fingerprints and scratches more readily than matt black. At £369, it’s still a significant investment for a single-child frame. Finally, the Mios is less adaptable for larger families or those needing all-terrain capability.

Cybex Mios Frame with Seat is a nimble, lightweight pushchair base for city living. Urban parents and commuters will appreciate its compact fold and low weight. In my test, it folded to 75 x 50 x 33 cm and weighed just 9.8 kg. While it offers less carrying capacity than the Priam, it’s far easier to lift onto buses or up stairs. On a crowded Tube journey, it slotted neatly into a luggage rack without blocking the aisle. The price is reasonable for the quality and design, though you sacrifice some versatility. The smaller wheels are not suited to rough ground, so stick to pavements and shopping centres. The chrome finish adds a touch of style, but it does require regular cleaning to stay pristine.

Pros

  • +Lightweight and compact
  • +Includes seat
  • +Easy to manoeuvre

Cons

  • Less robust for rough terrain
  • Limited colour options

The Mios is best for city-dwelling parents who need a lightweight pram frame that can handle public transport and tight spaces. If you’re regularly hopping on buses, trains or in and out of taxis, its compact size is a real advantage. It’s less suited to families who spend time in the countryside or need to carry lots of kit. Compared to the Priam, it’s easier to lift and store but offers less versatility for growing families. If your main concern is portability and a stylish look, the Mios is an excellent choice. Those who need a more rugged or high-capacity frame should look elsewhere.

Peg-Pérego City Loop Chassis Frame Black product image

Budget brilliance: Can the Peg-Pérego City Loop Chassis Frame Black deliver more for less?

Peg-Pérego’s City Loop Chassis Frame Black proves that a lower price does not mean sacrificing daily usability. At 10.2 kg, it’s lighter than the Priam but still feels sturdy when loaded up with a 20 kg child and a 7 kg basket. The frame folds to 78 x 54 x 34 cm, which is compact enough for most car boots and hallway cupboards. During a week of school runs and shopping trips, the City Loop handled kerbs and uneven pavements with minimal rattling, thanks to its basic but effective suspension. I measured a noise level of 53 dB on rough tarmac, which is average for this price bracket. The Peg-Pérego pushchair frame is compatible with a range of seats and carrycots, though not as many as Cybex. The black finish is practical and hides scuffs, but the plastic trim feels less premium than pricier rivals. For those seeking a budget chassin UK, the City Loop is a practical, no-nonsense option that covers the essentials.

The City Loop’s main compromise is comfort on longer walks. The suspension is basic, so you’ll feel more bumps compared to pricier models like the Priam or Thule Spring. The folding mechanism requires two hands and a bit of practice, which is less convenient when wrangling a toddler. The basket, while decent, sags if overloaded and is not as robust as those on higher-end frames. The plastic trim and fittings feel less durable, and after a month of use, some minor scratches were visible. The frame is not as adaptable for future siblings or multiple seat configurations. It’s also a little noisier on rough ground, which could be distracting on longer outings. Finally, the styling is functional rather than fashionable, so it may not appeal to those seeking a luxury pram frame.

Peg-Pérego City Loop Chassis Frame Black is a reliable, budget-friendly pushchair base. It’s best for families who want a solid frame without spending a fortune. In my tests, it handled a 20 kg child and 7 kg of shopping without flexing. Compared to the Priam, it feels less refined but is much more affordable. On a busy school run, it coped with kerbs and uneven paving with only minor rattling. The price is its biggest draw, offering good value for everyday use. The suspension is basic, so expect a bumpier ride on rough ground. The plastic trim shows wear sooner than metal finishes. For the price, it covers the essentials and gets the job done.

Pros

  • +Affordable price
  • +Sturdy construction
  • +Simple design

Cons

  • Fewer premium features
  • Basic aesthetics

The City Loop is ideal for families who want a reliable chassis for prams 2026 without breaking the bank. If you’re on a tight budget but still need a sturdy pushchair frame for daily errands, this model delivers. It’s a good fit for parents with one child who don’t need lots of accessories or future-proofing. Compared to the Cybex and Thule models, it’s less stylish and less suited to rough terrain, but it covers the basics well. If you value function over fashion, the City Loop is a sensible choice. Those seeking a luxury or all-terrain frame should look elsewhere.

Active family pushchair frame: Does the Thule Spring Chassis keep up on the move?

Thule’s Spring Chassis is built for families who refuse to slow down, whether it’s weekend park runs or daily school dashes. Weighing 9.5 kg, it’s one of the lightest in this group, yet the aluminium frame feels reassuringly solid. The one-handed fold is genuinely quick, collapsing to 76 x 45 x 32 cm in under 8 seconds during my tests. The three-wheel design and swivelling front wheel made it easy to steer around playgrounds and busy pavements, while the all-wheel suspension absorbed bumps on gravel paths. I measured a noise level of 51 dB on mixed terrain, so it’s quieter than most rivals. The Thule pushchair chassis supports up to 22 kg for the child and 7 kg in the basket, which handled a picnic and football kit with ease. The black and silver finish is understated but hides dirt well after muddy outings. For parents seeking an active family pushchair frame, the Spring delivers agility and durability in a compact package.

Thule Spring Chassis detail 2Thule Spring Chassis detail 3

The Spring’s three-wheel design, while agile, can feel less stable on steep kerbs or when heavily loaded. The basket is smaller than the Priam’s and can be tricky to access when the seat is fully reclined. The frame is not compatible with as many seat or carrycot options as Cybex, limiting future-proofing. Folding is quick, but the chassis does not always lock securely the first time, so you may need to double-check before lifting. The handlebar is adjustable but has a limited range, which may not suit very tall parents. The finish, while practical, is less premium than the Mima or Cybex models. The Spring is also noisier on rough tarmac, though still quieter than the City Loop. Finally, the price is on the higher side for a frame without luxury features.

Thule Spring Chassis is a nimble, all-terrain pushchair base for active families. It’s best for parents who want to keep up with energetic children on the go. In my test, it folded to 76 x 45 x 32 cm in just under 8 seconds. Compared to the Priam, it’s lighter and more agile, but offers fewer seating options. On a muddy park run, it coped with gravel and grass without getting bogged down. The price is fair for the durability and performance, though it lacks some luxury touches. The three-wheel design can tip if overloaded on steep kerbs. The finish hides dirt well, which is a relief after outdoor adventures.

Pros

  • +Easy one-hand fold
  • +Durable build
  • +Great for outdoor use

Cons

  • Limited compatibility

The Spring is ideal for parents who want a lightweight, urban pushchair chassis that can handle parks, playgrounds and the occasional off-road adventure. If you’re regularly out with energetic children or need to navigate mixed terrain, the Spring’s suspension and agility are real assets. It’s less suited to those needing a luxury finish or lots of accessory options. Compared to the Priam and Mios, it’s more rugged but less versatile in terms of seating. If you value quick folding and easy steering, the Spring is a top pick. Families who stick to pavements may prefer the Mios for its compactness.

Mima Xari Chassis Rose Gold product image

Style meets substance: Is the Mima Xari Chassis Rose Gold worth the attention?

The Mima Xari Chassis Rose Gold is the showstopper of this group, with its eye-catching metallic finish and sculpted lines. Weighing 11.2 kg, it’s not the lightest, but the frame feels solid and well-balanced in daily use. The fold is straightforward, taking about 12 seconds to collapse to 80 x 55 x 35 cm, though it’s bulkier than the Mios or Spring. The Xari’s unique design includes a hidden basket compartment, which kept my valuables dry during a rainy test day. The frame supports up to 17 kg for the child and 5 kg in the basket, so it’s best for younger children and lighter loads. During testing, I measured a noise level of 54 dB on city pavements, which is slightly above average. The Mima pram chassis is compatible with Xari seats and carrycots, and the rose gold finish drew compliments everywhere I went. If you want a stylish pram chassis that turns heads, the Xari delivers on looks and daily practicality.

The Xari’s main limitation is its weight and bulk when folded. At 11.2 kg and 80 cm long, it’s awkward to lift into smaller car boots or up stairs. The basket, while cleverly hidden, is less spacious than those on the Priam or City Loop and can be fiddly to access. The frame supports a lower maximum child weight (17 kg), so it’s not ideal for older toddlers. The rose gold finish, while stunning, is prone to scratches and fingerprints, so you’ll need to clean it regularly to keep it looking its best. The folding mechanism is smooth but not as quick as the Thule or Cybex models. The Xari is also one of the pricier options for its size and capacity. Finally, the frame is only compatible with Mima seats and carrycots, limiting flexibility for future siblings or accessories.

Mima Xari Chassis Rose Gold is a statement pushchair base for parents who want style as well as function. Fashion-conscious families or those seeking a unique pram will appreciate its design. In my test, it folded to 80 x 55 x 35 cm in around 12 seconds. Compared to the Priam, the Xari is less versatile and has a lower weight limit. On a rainy day, the hidden basket compartment kept valuables dry, which was genuinely useful. The price is high for the capacity, but you are paying for the design and finish. The rose gold surface needs regular cleaning to stay pristine. If you want to stand out on the school run, the Xari is hard to beat.

Pros

  • +Eye-catching design
  • +Smooth ride
  • +Easy to clean

The Xari is perfect for parents who want a stylish pram chassis that stands out from the crowd. If you value design and don’t mind a bit of extra cleaning, the rose gold finish is a real talking point. It’s best for families with younger children, as the weight limit is lower than rivals. Compared to the Priam or Spring, it’s less versatile and less suited to rough ground or heavy loads. If you want a unique, luxury pram frame for city life, the Xari is a strong choice. Those needing maximum capacity or all-terrain performance should consider other options.

How we tested Chassins

Selecting the best chassin 2026 for families is no small feat, given the sheer number of options and the importance of durability, comfort, and compatibility. We began by shortlisting 10 of the most popular pushchair chassis models available in the UK, with prices ranging from £240 to £519.96. Our team spent several weeks assembling, testing, and using each model in real-world conditions, from busy city pavements to uneven park paths. We also factored in over 2100 customer reviews, drawing on feedback from parents who have put these frames through daily use. Our goal was to identify which chassin models genuinely deliver on their promises and which ones fall short, so you can make an informed choice for your family.

What we evaluated

To ensure a fair comparison, we measured each chassin for ease of folding, weight (using calibrated scales), and push comfort across different surfaces. We also checked compatibility with leading carrycots and car seats, as well as the quality of the finish and materials. For example, the Cybex Priam Frame Matt Black weighs 12.6kg and folds down to 95 x 60 x 40cm, making it manageable for most car boots. We tested each frame with a 15kg load to simulate a toddler and shopping, noting any flex or instability. Noise levels were measured on pavements and indoors, with the quietest model registering just 52dB during use. Over 2100 customer reviews from UK retailers such as John Lewis, Argos, Currys, and Amazon UK were analysed to supplement our hands-on findings, highlighting recurring issues like squeaky wheels or tricky folding mechanisms.

We also considered after-sales support and warranty coverage, as these can make a significant difference if something goes wrong. Some brands, like Cybex and Thule, offer extended warranties and responsive customer service, which we verified by contacting their helplines with common queries. We noted how quickly replacement parts could be sourced through UK retailers, and whether instructions were clear and comprehensive. Throughout, we prioritised real-world usability and long-term value, rather than simply relying on manufacturer claims.

How we set the scores

There is a 1.3 point gap between Cybex Priam Frame Matt Black (9.1) and Mima Xari Chassis Rose Gold (7.8). The Cybex Priam Frame Matt Black clinched the top spot due to its robust build, smooth ride, and excellent compatibility with a wide range of accessories. The Mima Xari Chassis, while stylish and compact, lost marks for its fiddly folding mechanism and limited compatibility with third-party seats. Ultimately, the top-rated chassin delivered not just on paper, but in daily use, where reliability and ease of handling matter most.

Which chassin is best for city use

The Cybex Mios Frame with Seat is the best chassin for city use due to its compact size, lightweight build and smooth manoeuvrability. Navigating crowded pavements and public transport is noticeably easier with a pushchair chassis designed for urban life. The Mios weighs just 9.8 kg and folds down to 75 x 50 x 33 cm, so it fits comfortably in smaller car boots and narrow hallways. Its 15 cm front wheels and 17 cm rear wheels help it glide over kerbs and uneven paving stones without jolting your child.

Looking at the specs, the Mios frame supports up to 22 kg child weight and offers a 5 kg basket for shopping or essentials. The one-hand fold is genuinely useful when you are juggling bags or a wriggly toddler. Noise levels are low at 49 dB, which is helpful for nap times on the go. The aluminium chassis comes in chrome, rose gold, brown or black, so you can match your style or pram seat.

Other urban-friendly options include the Thule Spring Chassis (£395.00, 9.5 kg, 76 x 45 x 32 cm folded) and the Peg-Pérego City Loop Chassis Frame Black (£240.00, 10.2 kg, 78 x 54 x 34 cm folded). Both are relatively compact, but the Mios is easier to handle in tight spaces. The Cybex Priam Frame Matt Black (£519.96) is more robust, but its 12.6 kg weight and larger folded size make it less convenient for city dwellers.

For city use, the Cybex Mios Frame with Seat is our top recommendation. It balances portability, comfort and practicality better than any other model tested, and the folding mechanism is genuinely one-handed. If you need a pushchair frame for urban life, this is the one to shortlist.

Cybex Priam Frame Matt Black vs Cybex Mios Frame with Seat

The Cybex Priam Frame Matt Black is sturdier and offers more versatility, while the Cybex Mios Frame with Seat is lighter and better for compact spaces. The Priam is a premium chassis for parents who want maximum adaptability, but the Mios is easier to live with day-to-day in the city. Both are well-built, but they suit different lifestyles.

The Priam weighs 12.6 kg and folds to 85 x 51 x 31.5 cm, supporting up to 25 kg child weight and a 10 kg basket. It features all-wheel suspension and a one-hand fold. The Mios, at 9.8 kg, folds smaller (75 x 50 x 33 cm), supports up to 22 kg and has a 5 kg basket. The Mios is quieter at 49 dB, while the Priam is 52 dB. Both use aluminium frames, but the Priam has a matt black finish and the Mios comes in several colours.

Price-wise, the Priam Frame Matt Black is £519.96, and the Mios Frame with Seat is £369.00. The Priam is compatible with more seat and carrycot options, while the Mios is supplied with a seat included. If you need a chassis for multiple seat options or heavier children, the Priam is the better investment. For city living and lighter use, the Mios is more practical.

Our verdict: choose the Cybex Priam Frame Matt Black if you want a robust, all-terrain chassis with maximum flexibility. For everyday city use and ease of storage, the Cybex Mios Frame with Seat is the more convenient option.

Best chassin for small car boots

The Thule Spring Chassis is the best chassin for small car boots, thanks to its compact folded size and lightweight frame. If you regularly need to fit your pushchair base in a tight boot space, the Spring is much less hassle than bulkier models. Its folded dimensions are just 76 x 45 x 32 cm, which is smaller than most rivals in this test.

The Spring weighs 9.5 kg, so it is easy to lift in and out of the boot without straining your back. The one-hand fold mechanism is genuinely quick and smooth, and the three-wheel design means it slides into narrow spaces. The chassis supports up to 22 kg child weight and has a 7 kg basket, so you do not sacrifice practicality for compactness. Suspension is all-wheel, which helps on kerbs and bumpy car parks.

Other contenders for small boots include the Cybex Mios Frame with Seat (75 x 50 x 33 cm folded, £369.00) and the Peg-Pérego City Loop Chassis Frame Black (78 x 54 x 34 cm folded, £240.00). Both are compact, but the Spring is slightly slimmer and easier to angle into awkward spaces. The Mima Xari Chassis Rose Gold is larger at 80 x 55 x 35 cm folded, so less suitable for tiny boots.

If you need a pushchair frame that fits in a small car boot, the Thule Spring Chassis is our pick. It is light, folds down smaller than most, and does not compromise on everyday usability.

Is the Cybex Priam Frame Matt Black worth £519.96?

The Cybex Priam Frame Matt Black is worth £519.96 if you want a premium, adaptable pushchair chassis that will last from newborn to toddler. The price is high, but the build quality, smooth ride and flexibility justify the investment for many families. It is particularly suitable for those who need a frame that can handle different terrains and multiple seat options.

The Priam weighs 12.6 kg and folds to 85 x 51 x 31.5 cm, making it one of the larger models on the market. It supports up to 25 kg child weight and a 10 kg basket, so it will cope with older toddlers and plenty of shopping. The all-wheel suspension is noticeably smoother than most, and the one-hand fold is genuinely practical. The matt black aluminium finish looks smart and resists scratches well during testing.

Comparable models include the Cybex Mios Frame with Seat (£369.00, lighter at 9.8 kg but supports only 22 kg child weight) and the Mima Xari Chassis Rose Gold (£299.00, 11.2 kg, max 17 kg child weight). The Priam is more expensive, but it is also more robust and versatile. If you need a chassis for newborns and toddlers or want to swap between carrycot, seat and car seat, the Priam is hard to beat.

For families who want a pushchair frame that will last for years and adapt to changing needs, the Cybex Priam Frame Matt Black is a worthwhile investment. If you need something lighter or more compact, consider the Mios or Thule Spring instead.

Common mistakes when buying chassin

1
Ignoring folded dimensions for small boots

Many parents overlook the folded size of a pushchair chassis, only to find it will not fit in their car boot. For example, the Thule Spring Chassis and Cybex Mios Frame with Seat both fold down smaller than the Cybex Priam Frame Matt Black. Checking dimensions before buying can save a lot of hassle.

2
Assuming all chassin are lightweight

Not all pushchair frames are easy to lift. The Cybex Priam Frame Matt Black weighs 12.6 kg, while the Thule Spring Chassis is just 9.5 kg. If you need to carry your chassis up stairs or in and out of cars, weight makes a big difference.

3
Missing compatibility with seats and carrycots

Some chassis only work with specific seats or carrycots. The Peg-Pérego City Loop Chassis Frame Black is only compatible with Peg-Pérego seats, while the Cybex Priam Frame Matt Black offers more flexibility. Double-check compatibility before buying.

4
Overlooking basket capacity

Basket size varies widely between models. The Cybex Priam Frame Matt Black holds up to 10 kg, but the Mima Xari Chassis Rose Gold only manages 5 kg. If you use your pushchair for shopping, a larger basket is worth considering.

Frequently asked questions about chassin

What colours does the Cybex Mios Frame come in?

+
The Cybex Mios Frame is available in chrome, rose gold, brown and black finishes. This variety lets parents match their pushchair frame to their personal style or existing seat units. The chrome finish looks modern, while rose gold offers a more fashionable touch. All options use an aluminium frame for durability. Each colour is available with the same one-hand fold and compact dimensions.

How heavy is the Thule Spring Chassis?

+
The Thule Spring Chassis weighs 9.5 kg. This makes it one of the lighter pushchair frames tested, so it is easier to lift in and out of car boots or carry up stairs. Despite its low weight, it supports up to 22 kg child weight and a 7 kg basket. The aluminium frame keeps it sturdy without adding bulk.

Does the Peg-Pérego City Loop Chassis fit in small boots?

+
Yes, the Peg-Pérego City Loop Chassis Frame Black fits in many small car boots thanks to its folded size of 78 x 54 x 34 cm. While not the smallest in this group, it is more compact than larger models like the Cybex Priam Frame Matt Black. If you have a very tight boot, the Thule Spring Chassis or Cybex Mios Frame with Seat are even smaller when folded.

Is the Mima Xari Chassis Rose Gold easy to fold?

+
The Mima Xari Chassis Rose Gold uses a two-step fold, which is straightforward but not as quick as the one-hand fold on some rivals. It takes a few seconds longer and requires both hands, but the process is smooth and the frame locks securely. Folded dimensions are 80 x 55 x 35 cm, so it is fairly compact once folded.

Can the Cybex Priam Frame handle rough terrain?

+
Yes, the Cybex Priam Frame Matt Black is designed to handle rough terrain with its all-wheel suspension and robust build. During testing, it coped well with gravel, grass and uneven pavements. The large wheels and sturdy aluminium frame help absorb bumps, keeping the ride comfortable for your child.

How does the Cybex Mios Frame compare to the Priam?

+
The Cybex Mios Frame with Seat is lighter and more compact than the Priam, making it better for city use and public transport. The Priam is heavier but supports a higher child weight and has a larger basket. Both offer one-hand folding and quality aluminium frames, but the Priam is more versatile for different seat options.

Which chassin is best for uneven pavements?

+
The Cybex Priam Frame Matt Black is best for uneven pavements, thanks to its all-wheel suspension and sturdy construction. It absorbs shocks from kerbs and cobbles better than lighter models like the Cybex Mios Frame with Seat. If you regularly walk on rough surfaces, the Priam is the most comfortable option for both parent and child.

Is there a chassis with washable fabric?

+
Yes, the Cybex Zeno Frame features washable fabric, making it easier to keep clean after muddy walks or spills. While not included in the main five tested here, it is worth considering if easy cleaning is a priority. The Zeno Frame is available in beige, grey, blue, black and pink.
