Oyster 4 Review: A UK Pushchair That Grows Into a Double?
Short answer: The Oyster 4 is a good-value UK pushchair that starts as a single and takes a tandem seat later, but it is sold in the UK, not the US. Oyster lists it at £629 for the stroller alone and 12.6 kg (27.8 lb) with the seat. The seat lies flat from birth, faces either way and folds one-handed with the seat attached.

The Oyster 4 from Babystyle is one of the better-value full-size pushchairs in the UK, at £629 for the stroller alone on Oyster's own site. John Lewis lists a reversible seat that lies flat from birth, a one-hand fold with the seat on, and puncture-free tyres. The basket is modest at 5 kg (11 lb), and the carrycot, tandem seat and car seat adaptors cost extra. It was released in August 2025 and is sold in the UK, not the US.
Who is the Oyster 4 for?
The Oyster 4 is for UK parents who want a full-size pushchair with a reversible seat at a fair price. Babystyle makes it, and Oyster lists it at £629 for the stroller alone; Which? gave a typical price of £599. It is sold in the UK, not the US. Which? says it was released in August 2025, replacing the Oyster 3. Add the Oyster4 Tandem Seat and it carries two children, each up to 15 kg. The seat works from birth, so you can skip the carrycot if your budget is tight. If you want a large basket or plan lots of rough country walks, look at a bigger or all-terrain pushchair. For pavements, shops and car trips, it covers the basics well.
How does the Oyster 4 ride and steer?
John Lewis lists four solid, puncture-free tyres on the Oyster 4, with front wheels that swivel or lock and wheels that come off for cleaning or packing. Which? confirms the tyres are not air-filled. Solid tyres need no pumping, though they pass on more bumps than air tyres on rough ground. At 58 cm wide per John Lewis, it fits most doorways and shop aisles. It is a town and park pushchair, not a running or trail model.

How big is the Oyster 4 when folded?
Oyster lists the Oyster 4 chassis at 7.8 kg and the seat at 4.8 kg, so 12.6 kg (27.8 lb) together; John Lewis gives 12.5 kg and Which? 12.3 kg. Both retailers describe a one-hand fold, and John Lewis says it folds with the seat attached and stands on its own. Oyster gives the folded size with the seat on and facing you as 69 x 58 x 32 cm, about 27.2 x 22.8 x 12.6 in, or 38 cm deep with the seat facing out. That suits most car boots. It is not an airline carry-on pushchair.
Is the Oyster 4 comfortable and safe?
The Oyster 4 seat lies flat for a newborn, per John Lewis, so it can be used from birth without the carrycot. It faces you or the world, reclines one-handed to three positions and has four leg-rest positions, per Which?. The child limit is 22 kg, about 48.5 lb. The handlebar adjusts from 101 to 113 cm. Oyster lists infant car seats from Oyster, Avionaut, BeSafe, Cybex, Maxi-Cosi and Peg Perego as compatible with its Multi Car Seat Adaptors, sold separately.
How much storage does the Oyster 4 have?
Oyster rates the Oyster 4 basket at 5 kg, about 11 lb, as do Which? and John Lewis. That is enough for a changing bag and a coat, but not a big food shop. If storage is a priority, a full-size pushchair with a 10 kg or larger basket will be easier to live with.

How does the Oyster 4 compare with US strollers?
The Oyster 4 is sold in the UK, not the US, so American parents can't buy it in stores. The closest US match is a full-size stroller with a reversible seat and a one-piece fold, such as the UPPAbaby Cruz V3 or the Nuna Mixx Next. Those cost more but have bigger baskets: 30 lb on the Cruz V3, against 5 kg (11 lb) on the Oyster 4. At £629 for the stroller alone, the Oyster 4 is cheaper than both in the UK.
