Layer Details
- Knitted Cover. A removable, washable knitted cover designed with breathability in mind, which means you can keep it fresh without replacing a protector every time. It's soft to the touch as well.
- Memory Foam. A 2cm layer of memory foam that moulds to your body, giving orthopaedic support and cushioning where you press into the mattress. It's a thin layer, so expect a gentle contour rather than a deep sink-in feel.
- EcoFoam®. A 13cm base made from 100% recycled and re-engineered foam, which means the supportive core of the mattress is resilient and durable while keeping waste out of landfill. It also has natural dust mite resistance, helpful for allergy-prone sleepers.

- Real room for one: At 30cm wider than the UK single, this size lets a solo adult stretch out, roll over and change position without meeting the edge.
- Fits compact double bedrooms: Being 15cm narrower than the UK double can be the difference between a door that clears the bed frame and one that doesn't.
- Sensible spec for a guest room: The 2cm memory foam layer over the EcoFoam® base suits occasional couples staying a night or two, without paying for depth that guests rarely notice.
- Easy bedding to find: Small double is a standard 4ft UK size, so fitted sheets and frames are widely stocked, and a standard double duvet works fine on top.
- Washable cover, shared spaces: The removable knitted cover can go in the wash, useful when different guests or a teenager use the bed over time.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't take a full double, you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or you're setting up a teenager's room and want more bed without losing all the floor space. Allow at least 2.4m x 2.8m of room for this size to work comfortably.
Consider another size if...
You share the bed every night, because 120cm across two adults gets tight, and the thin 2cm comfort layer offers little forgiveness when you're pressed together. We'd recommend the UK double instead, which gives 67.5cm each; allow at least 2.6m x 2.8m for it.

Is a small double memory foam mattress big enough for one adult?
Comfortably, yes. At 120 x 190cm the UK small double gives a solo sleeper 30cm more width than a UK single at the same length, which means you can spread out or shift position freely. The medium firm feel and 2cm memory foam layer suit lighter solo sleepers well.
Can a couple use the MattressNextDay Value Memory Foam in a small double?
For the odd night, yes, which is why it works in guest rooms. For nightly sharing it's a squeeze: two adults on 120cm of width, with a slim 15cm profile underneath. Couples using it every night would be better served by the UK double, which is 15cm wider.
What room size do I need for a UK small double?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to walk round the bed and open the door properly. If your room is smaller, the UK single needs 2.1m x 2.8m and is the same length, so you lose width rather than legroom.
Will this mattress fit in a box room or loft conversion?
Often, yes, and that's the main reason to pick this size. It's 15cm narrower than a UK double, which frequently decides whether a door still clears or there's standing room beside the bed under a sloped ceiling. Measure the room and allow at least 2.4m x 2.8m before committing.
