Layer Details
- High Density Memory Foam. A 2.5cm layer of high density memory foam that shapes around your body to relieve built-up pressure. You'll feel a gentle cradling at your hips and shoulders rather than a deep sink.
- Reflex Foam. The 15.5cm reflex foam layer responds to changes in movement or weight, tailoring support to the places that need it most. In practice, that means a stable, springy base that stops you feeling stuck in the mattress.

- Real space for one: At 120cm across, you get noticeably more stretching room than a UK single, which means solo sleepers can change position freely through the night.
- Fits compact rooms: The UK small double is 15cm narrower than a UK double, so it slots into box rooms and loft conversions where a bigger frame would block walking space.
- Pressure relief where you feel it: The 2.5cm high density memory foam layer cradles hips and shoulders, easing the pressure points a spreading solo sleeper actually leans into.
- Slim build, easy handling: At 18cm deep, this size is lighter to manoeuvre up narrow stairs than taller foam mattresses, a genuine help in lofts and small second bedrooms.
- Standard 4ft sizing: The small double is a standard UK size, so frames and fitted sheets are easy to find rather than a specialist order.
This size suits you if...
You sleep alone and have outgrown a single but your room can't spare the width of a full double, you're kitting out a guest room where couples stay occasionally rather than nightly, or you're furnishing a loft conversion or studio where every centimetre of floor decides whether the door still opens.
Consider another size if...
You share the bed every night and both of you like your own space, because 120cm gets snug for two adults long term. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m of room.

Is the Bodyshape Vitality small double big enough for two adults?
For occasional nights, yes. Couples can share a UK small double comfortably enough for a weekend stay, which makes this a practical guest room choice. For every night, the 120cm width feels tight once both of you settle in, and the memory foam's gentle cradling can't add space it doesn't have. Nightly couples should look at the UK double.
What size room do I need for a UK small double mattress?
We suggest allowing at least 2.4m x 2.8m. That gives you space to walk round the bed and open drawers without shuffling sideways. If your room is smaller than that, a UK single may serve you better; if it's comfortably bigger, the UK double becomes an option with our suggested minimum of 2.6m x 2.8m.
How much bigger is the small double than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. In practice that extra width is the difference between sleeping in one fixed position and being able to sprawl. On the Vitality, it also means more of the memory foam surface working for you rather than the mattress edge.
Will the small double Bodyshape Vitality suit a loft conversion or box room?
It's one of the better candidates. At 4ft wide it fits rooms where a standard double would leave no standing room beside the bed, and the slim 18cm build makes it easier to carry up tight staircases than a deeper foam mattress. Check your door swing against the 120 x 190cm footprint before ordering.
Is a small double a good upgrade for a teenager?
Often, yes. A teenager who has outgrown a single gets 30cm more width without the room losing the floor space a full double takes. The medium firm feel of the Vitality gives growing sleepers steady support, though the 2.5cm memory foam layer is slim, so anyone wanting a deep sink will feel the firmer base.
