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.

- The traditional couples' size: At 135 x 190cm, the UK double is the long-standing standard for two sharing, which means frames, sheets and duvets are easy to find at any budget.
- Fits the average British bedroom: We suggest a room of at least 2.6m x 2.8m, which leaves space for a wardrobe and drawers where a UK king would dominate.
- Room for bedside tables on both sides: In a typical double bedroom, this size usually still allows a table each, so nobody loses their lamp and phone charger.
- A sensible guest room pick: Visiting couples get a proper shared bed, and the low price suits a room that's slept in a handful of nights a year.
- Light enough to manoeuvre: At 15cm deep with a foam-only build, the UK double is easier to flex round turning stairs in older terraces than a sprung mattress of the same size.
This size suits you if...
You're kitting out a guest room or a first flat and want a shared-size bed without spending premium money, or you sleep alone and like space to spread out, perhaps with a dog or cat claiming a corner. It also suits you if your bedroom is around the typical UK size, where a UK double leaves room to actually walk around the bed.
Consider another size if...
You and your partner both want more personal space for nightly sharing, since 67.5cm each is a little snug on a thin foam mattress. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m of room.

Is the MattressNextDay Value Memory Foam in a UK double good for couples?
For occasional sharing, yes. A UK double gives 67.5cm each, which works well for visiting couples in a guest room. For every night, two adults pressing into a 2cm memory foam layer may notice each other more than on a deeper mattress, so full-time couples might prefer sizing up to the UK king.
Will a UK double fit in my second bedroom with other furniture?
Usually, yes. We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m the comfortable norm. In a typical second bedroom that leaves room for a wardrobe and a chest of drawers, which is exactly why this size remains the default for spare rooms and first flats.
Is this mattress easy to get upstairs in a double size?
Easier than most. The UK double measures 135 x 190cm but is only 15cm deep and all foam, so it flexes round tight turns better than a sprung double. That helps in older terraces with narrow staircases and new builds with tight landings, though it's still a two-person carry.
Should I get this mattress in a double or a small double?
The UK double is 15cm wider than the UK small double, and the two are the same length. For two people sharing, even occasionally, the UK double is the better choice. If your room is genuinely tight, the UK small double needs at least 2.4m x 2.8m and suits a solo sleeper.
What bedding do I need for this mattress in a UK double?
Standard double sheets and a 200 x 200cm double duvet, both stocked everywhere at every price. The mattress is slimmer than average at 15cm, so deep fitted sheets will bag slightly; standard-depth ones sit neater. The knitted cover is removable and washable, which cuts down how often you need to strip everything back.
