Ergobaby Metro3 vs Joolz Aer2: Which Compact Travel Stroller Should You Buy?

COMPARISON · ON THE GO

You are airport-bound, toddler on one hip, boarding pass in your teeth, trying to fold the stroller with your free hand - and it is not cooperating. Sound familiar? For parents who travel regularly or navigate tight city streets, a compact stroller that genuinely folds small, rides smoothly, and works from birth is not a luxury. It is survival gear.

The Ergobaby Metro3 and the Joolz Aer2 are two of the most talked-about compact strollers in the UK right now, and they take surprisingly different routes to solving the same problem. One leads with suspension and newborn readiness at a competitive price. The other delivers the fastest fold on the market, a 10-year warranty, and a Red Dot Design Award. Both carry children up to 22 kg through the toddler years, but a £118 price gap separates them.

We dug into specs, combed through thousands of parent reviews, and cross-referenced real-world feedback to find out where each one genuinely earns its keep - and where the marketing gets ahead of the experience.

How we picked the 2

We started with the full pool of compact strollers from joined-programme UK retailers, then filtered for in-stock models from established brands with genuine UK presence. From that shortlist, we looked for two strollers at different price points that genuinely compete for the same parent: the city dweller or frequent traveller who needs something that folds small, rides well, and handles from birth. The Metro3 and the Aer2 hit those criteria from different angles, making them a natural pairing.

What to look for in a compact stroller

Before diving into the two picks, here are the features that actually matter when you are choosing a compact stroller - and the ones that sound impressive on the box but rarely change day-to-day life.

Fold size and type. Every compact stroller claims to fold small. The real question is how it folds: one-hand or two-hand, whether it self-stands when folded, and whether you need to remove the seat or canopy first. A stroller that folds in one second but needs two hands is a very different experience from one that takes three seconds but only needs one.

Weight vs ride quality. Lighter strollers are easier to carry but often sacrifice suspension. A stroller under 7 kg that rattles over cobblestones will frustrate you as much as a smooth-riding 8 kg stroller you dread carrying up stairs. The sweet spot depends on how you split your time between carrying and pushing.

Newborn suitability. Some compact strollers work from birth with just a seat recline. Others need an aftermarket carrycot or cocoon. Check whether "from birth" means fully flat recline included in the box or accessories that add £100-200 to the total cost.

Basket access and size. The smaller the fold, the smaller the basket. If you are using the stroller for daily errands, a basket that holds a nappy bag and a small shop is essential. If it is purely for travel, you can get away with less.

Warranty and longevity. A compact stroller takes more mechanical stress than a full-size one because it folds and unfolds far more often. A longer warranty signals confidence in the hinges and joints surviving daily use.

Ergobaby Metro3 / 10 · Best Value

The Metro3 is Ergobaby’s answer to a question every parent asks eventually: can a compact stroller actually ride like a full-size one? The headline feature is CushionRide all-wheel suspension, which absorbs bumps, kerbs, and cobblestones in a way most compact strollers simply do not. Parents consistently single it out as the difference-maker. One parent told us: "The all-wheel CushionRide suspension really is impressive and so smooth. My baby sleeps almost immediately when placed in the recline mode."

The near-flat recline deserves its own mention. Ergobaby’s built-in Newborn Nest means you can use the Metro3 from birth without buying a separate carrycot, and the recline is genuinely close to fully flat. For parents who want one pushchair from day one through to 22 kg, this is a significant advantage, especially at a price point that undercuts most premium compacts by £100 or more.

The fold is where the Metro3 loses ground. It folds compactly (56 x 44 x 23 cm), but it requires two hands, and several parents report that the fold mechanism does not always lock securely on the first attempt. The brake pedal is also narrow and slightly recessed, making it tricky in sandals or flip-flops. These are not deal-breakers, but they are the kind of daily friction that matters if you fold and unfold multiple times a day.

What parents love

• CushionRide suspension. All-wheel suspension gives a noticeably smoother ride than almost any other compact stroller at this weight.
• Birth-ready out of the box. The built-in Newborn Nest and near-flat recline mean no extra accessories needed for newborns.
• Adjustable handlebar. Extends to fit taller parents comfortably, a feature the Aer2 does not offer.
• Competitive price. At roughly £241, it undercuts many premium compacts by a wide margin without sacrificing build quality.

What to know before you buy

• Two-hand fold. Both folding and unfolding require two hands, which is awkward when holding a child or bags.
• Fold lock inconsistency. Some parents report the fold does not always click securely on the first attempt.
• Basket access is tight. The 10 kg basket is generous on paper but harder to load with the seat reclined.
• Brake pedal design. The narrow, recessed pedal is not flip-flop friendly, a real consideration for summer or holidays.

Best for

• City parents who prioritise ride quality over the lightest possible weight
• Families wanting a birth-to-toddler stroller without buying separate newborn accessories
• Budget-conscious parents seeking premium features at a mid-range price
• Parents who value suspension for napping on the go

Joolz Aer2 / 10 · Best Overall

The Aer2 is Joolz’s lightweight travel stroller, and its party trick is the fold: one hand, one second, and it stands on its own. That is not marketing fluff. Parents confirm it consistently. "Folding is a dream: one hand, one second, and it stands on its own," one parent told us. For frequent flyers, this is the feature that ends the conversation. The folded Aer2 fits within IATA cabin-luggage dimensions and, at 6.5 kg, is light enough to lift into an overhead bin.

Beyond the fold, the Aer2 impresses with build quality that belies its weight. The chassis feels solid on pavement, gravel, and even sand, and the recycled PET fabric gives it a premium feel with a clear conscience. Joolz’s 10-year transferable warranty is the longest in the compact stroller category by a significant margin, and the Red Dot Design Award 2025 confirms the attention to detail. "It surprised me how sturdy and easy to handle the Aer2 was, even on sand and gravel," one parent shared.

The higher price, however, buys you the stroller and not much else. The bumper bar is sold separately, the Aer Cot for newborn use adds £229, and the Nest to Seat accessory for from-birth suitability is another £149. The handlebar is fixed at 106.5 cm with no height adjustment, which taller parents may find low. Suspension is limited to the front wheels, so the ride is noticeably firmer than the Metro3 on rough surfaces.

What parents love

• One-second, one-hand fold. The fastest fold on the market, self-standing when folded, IATA cabin-approved dimensions.
• Featherweight at 6.5 kg. One of the lightest premium compacts available, easy to carry through airports, up stairs, or onto public transport.
• 10-year transferable warranty. The longest warranty in the category, signalling confidence in build quality and benefiting resale value.
• Sustainable materials. Recycled PET fabrics and a smaller environmental footprint for eco-conscious families.

What to know before you buy

• Expensive accessories. Bumper bar, carrycot, and Nest to Seat are all sold separately, pushing the true from-birth cost well above the headline price.
• Fixed handlebar. At 106.5 cm with no adjustment, taller parents may find it uncomfortably low.
• Front-wheel suspension only. The ride is noticeably firmer than strollers with all-wheel suspension, particularly on cobblestones and rough paths.

Best for

• Frequent flyers who need a genuinely cabin-approved stroller
• Urban parents prioritising the lightest weight and quickest fold
• Eco-conscious families who value sustainable manufacturing
• Parents planning to use from 6 months onward without newborn accessories

How to choose

If ride quality and newborn readiness matter most, the Ergobaby Metro3 is the stronger choice. CushionRide suspension smooths out rough surfaces in a way the Aer2 cannot match, and the built-in Newborn Nest means you are ready from day one without spending another penny. At £241, it delivers premium features at a price that feels almost too competitive. The trade-off is a two-hand fold and slightly heavier carry weight.

If you travel often and the fold is everything, the Joolz Aer2 earns its premium. One hand, one second, cabin-approved, self-standing. No other compact stroller folds this fast or this reliably. The 10-year warranty adds long-term peace of mind that offsets the higher upfront cost. Just budget for the accessories if you need it from birth.

Add it to your Nest

Whichever stroller suits your family, you can add it to your free BubsNest registry and let friends and family know exactly which one you have chosen. One less thing to carry through the airport.
