Layer Details
- Top layer. A body-contouring memory foam layer that moulds to your shape, which means personalised comfort at every point of contact. You'll feel a gentle cradling rather than lying on top of the mattress.
- EcoFoam® layer. A recycled, breathable EcoFoam® layer that lets your heaviest pressure points dip slightly into the surface. This helps position your back properly, and the breathability keeps things a little cooler than solid foam alone.
- Pocket springs. Up to 1000 individually pocketed springs that move independently, which means support targeted to key areas of your body rather than the whole bed shifting when you do. They deliver the medium-firm feel.
- Border. A foam-encapsulated border that maintains the mattress's structure right to the edge. You can spread out and use the full surface without a soft, saggy perimeter.

- The classic shared size: At 135 x 190cm you get the standard UK couples' footprint, which fits comfortably in rooms where a UK king would crowd everything else out.
- 67.5cm each for two sharing: Two people get 67.5cm of width apiece, enough for most couples who sleep reasonably close rather than starfishing.
- Springs that ignore your partner: The 1000 pocket springs move independently, which matters more in a UK double than a solo size: one of you turning over shouldn't wake the other.
- Edges you can actually use: The foam-encapsulated border keeps the perimeter supportive, so on a shared 135cm surface neither of you loses usable space to a saggy edge.
- Kind to modest rooms and budgets: We suggest a room of at least 2.6m x 2.8m, which most UK bedrooms clear, and the low price leaves budget for the frame and bedding.
This size suits you if...
You share the bed every night and want the traditional couples' size that fits a typical UK bedroom, you're furnishing a first flat or a whole house at once and need the bed sorted without a big outlay, or you sleep alone and want space to spread out, perhaps with a dog or cat who's claimed a corner.
Consider another size if...
You and your partner both want more personal space than 67.5cm each. We'd recommend the UK king instead, which gives 75cm per person and is 10cm longer; allow a room of at least 2.7m x 2.9m for it.

What are the dimensions of the Simply Memory Pocket 1000 in a UK double?
The UK double measures 135 x 190cm, or 4ft 6in x 6ft 3in. That's 15cm wider than the UK small double and the same length, so it steps up sharing space without needing a longer bed frame. Standard double sheets and a 200 x 200cm double duvet fit it.
How much space does each person get on this mattress in a UK double?
Two people sharing get 67.5cm of width each. That's comfortable for most couples, and the independent pocket springs help by keeping movement on one side from travelling across the bed. If you both sprawl, the UK king gives 75cm each, so the UK double gives 7.5cm less per person.
Will the UK double fit in a smaller bedroom?
Usually, yes. We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves space to walk round the bed and, in most rooms, to fit bedside tables on both sides alongside a wardrobe. Measure your room before deciding, including where doors swing.
Is the UK double easy to get upstairs?
Easier than most sizes at this width. The mattress arrives rolled and boxed, so it goes up a turning staircase in an older terrace or across a tight new build landing far more easily than a full-size mattress would. Unroll it in the room where it will live, since it expands once opened.
Is this a good UK double for a guest room?
It suits guest rooms well. The medium-firm feel works for most back and combination sleepers, which matters when you can't predict who's visiting, and the UK double accommodates visiting couples where a UK single wouldn't. The low price also makes sense for a bed that's used occasionally rather than nightly. Compare the retailers listed on this page for current prices.
