A foldable rowing machine gives you a full-body, low-impact cardio session and then gets out of the way. The good ones stand on end in about the footprint of a dining chair (the YPOO below takes up just 1.29 sq ft stored), roll away on front wheels and come back out in under a minute, which makes a rower realistic in a UK flat or a spare room that still has to work as a spare room.
Folding designs do ask for compromises, and the listings rarely admit them. Shorter rails cramp tall rowers, lighter frames drop the weight limit (the Viavito tops out at 120kg against 159kg for the DMASUN), and "folds away" can mean anything from a hinged rail to tipping the whole machine onto its end. We compared the leading foldable rowing machines on Amazon UK on those points as well as resistance and price, and these five are the ones we'd spend our own money on.
How we chose
We prioritised genuinely foldable designs, smooth and quiet resistance, build quality and weight capacity, and value for money. Each pick below is suited to a slightly different buyer, so there's something here for most homes and budgets.

The JLL Ventus 2 Air is our top pick overall, combining air resistance with 8 levels of magnetic resistance for a smooth, satisfying workout that's easy to dial in. The ergonomically designed handle gives a comfortable, stress-free grip, and the aluminium-and-steel frame keeps the action quiet enough to row early in the morning or late at night without disturbing the house.
It's also genuinely easy to live with. The frame folds away and is light enough to move between sessions, and it assembles straight out of the box with no screws or tools required. The 8-level magnetic resistance lets you ramp from a gentle warm-up to a tough cardio session, so it grows with your fitness rather than getting boring.
Pros
Cons

The DMASUN pairs an upgraded titanium alloy flywheel system with a generous 350lb (159kg) maximum user weight, making it a reassuring choice for taller or heavier rowers. It suits heights from about 5ft 3in to 6ft 4in, and the magnetic resistance system delivers a smooth, near-silent stroke even at higher levels, so it stays quiet during intense sessions.
It's built for convenience too. The 16 adjustable resistance levels let you target different intensities, while built-in transport wheels make it easy to move and it stows upright to save about 90% of its floor space. Oversized non-slip pedals add security, and the LCD tracks time, count, speed, distance, calories and total distance. Bluetooth connects it to Kinomap and other apps, and DMASUN backs it with a 3-year manufacturer's service.
Pros
Cons

If you'd rather skip a long build, the YPOO arrives 80% pre-assembled and most people have it ready in about 10 minutes, which is the fastest setup of anything here. With 16 levels of magnetic resistance and a 350lb (159kg) capacity, it offers a quiet, low-impact workout suitable for users of most ages and fitness levels.
It is also the best folder on this list. Stowed upright it saves around 95% of its floor space and occupies just 1.29 sq ft, and built-in wheels make it simple to move. The dual slide rails add stability, the 63.58 inch range suits users from about 4ft 5in to 6ft 2in, and there's a holder for your phone or tablet. The LCD covers total count, time, strokes per minute and calories.
Pros
Cons

The Viavito Sumi is our pick for value, offering up to 10 levels of silent, friction-free magnetic resistance at an affordable price. It works your arms, back, shoulders, quads and legs, with a contoured, ergonomically designed seat that keeps the rowing motion smooth and comfortable.
Despite the price, the build feels solid: a rustproof stainless-steel frame, an aluminium seat frame and metal ball bearings should keep it going for years, with a 120kg maximum user weight. Its quick-folding design and removable ergonomic handgrips make it easy to lift and store away when space is tight.
Pros
Cons

For those who want a premium, feature-rich machine, the MERACH R50 Air steps things up with a 10-level air resistance system that peaks at around 50kg, so the stroke gets harder the faster you pull rather than sitting at a fixed setting. That is the closest feel to rowing on water you'll get on this list, and the extended steel track and adjustable footplates let you fine-tune your leg position and posture.
It's the most fully featured option here. A professional performance monitor delivers accurate workout data and connects over Bluetooth to the Merach app, there's a device holder for your phone or tablet, and you can sync heart rate from an Apple Watch or Garmin. It supports users up to 158kg, arrives 90% pre-assembled, and folds into two sections for vertical storage at 138 x 83 x 73cm.
Pros
Cons
How it folds. Some rowers fold the rail up on a hinge, which shortens the machine but leaves it sitting at roughly knee to hip height. Others, like the YPOO, DMASUN and MERACH R50, tip onto their front end and stand upright, which is how you get the stored footprint down to around a square foot or two. Upright storage saves the most floor; just check there's nothing low on the wall where it'll lean.
Rail length against your height. This is where cheap folders fall down. The YPOO suits roughly 4ft 5in to 6ft 2in and the DMASUN goes up to about 6ft 4in, while the Viavito's 88cm roller rail is short enough that taller rowers can run out of track at the finish of the stroke. If you're over six foot, check the stated height range or inseam before you look at anything else.
Weight limit. Hinges and lighter frames tend to pull the maximum user weight down. On this list it runs from 120kg (Viavito) up to 158kg for the MERACH and 159kg for the DMASUN and YPOO.
Space in use, not just in storage. People measure the corner it'll live in and forget where they'll row. Even a compact rower needs the best part of two metres of floor once it's unfolded and you're at full reach, so measure both spots.
A foldable rowing machine is the easiest way to get a proper full-body cardio machine into a home that doesn't have a spare room for a gym. Any of the rowers above will do the job and then disappear when you're done. If you want one recommendation, the JLL Ventus 2 Air is our top choice for most people, while the Viavito Sumi is the smartest pick on a tighter budget.
Yes. Foldable rowers give you the same full-body, low-impact workout as a fixed machine, then tuck away into a corner or cupboard when you're done. For the best results, choose one with an adjustable resistance system and comfortable foam handles.
The JLL Ventus 2 Air is our top pick for a lightweight, collapsible rower that's easy to live with at home. The Viavito Sumi is the best value if you're on a tighter budget.
Many do. Foldable rowers typically pivot or hinge so the rail folds up against the frame, and most have transport wheels so you can roll them out of sight. They're ideal if you don't have space for a permanent setup.
Rowing is a true full-body movement. It works your legs, glutes and core on the drive, and your back, shoulders and arms on the pull, which is why it burns calories quickly compared with upper-body-only equipment.
