Layer Details
- Memory Foam. A memory foam layer that cradles to your unique shape, which means a cushioned, cosy feel as you settle in. It's the layer doing the pressure-relief work.
- Pocket Springs. 1000 individual springs, each encased in its own cloth pocket, adapting to movement to give personalised support across your body. Because the springs move independently, you should feel less disturbance when a partner shifts.

- Room for two in a normal bedroom: At 135cm wide, the UK double gives couples a proper shared bed while leaving space for wardrobes and drawers in a typical UK room.
- 67.5cm each for two sharing: Two people get 67.5cm each, which is workable for most couples, and the pocket springs limit disturbance when one of you shifts.
- Bedside tables on both sides: In a room of at least 2.6m x 2.8m, our suggested minimum, the UK double usually still allows a bedside table on each side.
- A budget-friendly way to furnish a shared room: If you're kitting out a whole home at once, this size in a value hybrid keeps costs down without dropping to a cramped small double.
- Easy to dress and easy to move: Double bedding is stocked everywhere at every price, and the 20cm profile is more manageable on turning stairs than deeper premium hybrids.
This size suits you if...
You share the bed every night and your room comfortably fits a 135cm frame, you sleep alone but want space to spread out, perhaps with a pet claiming a corner, or you're setting up a guest room that needs to host visiting couples. Allow at least 2.6m x 2.8m of floor space, with around 3m x 3m the comfortable norm.
Consider another size if...
You and your partner both like room to sprawl, since 67.5cm each is a squeeze for restless sleepers. We'd recommend the UK king instead: it gives 75cm each and 10cm more length, in a room of at least 2.7m x 2.9m.

Is the Memory Zone 1000 Pocket in a UK double big enough for a couple?
For most couples, yes. The UK double gives 67.5cm each for two people sharing, and the 1000 pocket springs move independently, so you feel less of your partner's movement. Restless sleepers or anyone used to spreading out may find it snug, in which case sizing up to the UK king gives 75cm each.
What room size do I need for the Memory Zone 1000 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That minimum usually leaves room for bedside tables on both sides plus a wardrobe, which is why the UK double remains the default for typical British bedrooms where a UK king would crowd the space.
Should I get this mattress in a UK double or a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is on the smaller side or you want to keep bedding costs down; choose the UK king if you share with a restless partner or either of you is tall, and your room allows at least 2.7m x 2.9m.
Is the UK double Memory Zone 1000 a good guest room mattress?
It suits a guest room well. The UK double can host visiting couples as well as solo guests, and because this is a value hybrid, you're getting memory foam comfort and pocket spring support without premium spending on a bed used occasionally. The medium firm feel suits most sleeping positions, which matters when you can't predict your guests' preferences.
Is a UK small double much smaller than this UK double?
The UK double is 15cm wider than the UK small double, and both are the same length at 190cm. That extra width matters for couples: it takes the bed from cosy to comfortable for two. A UK small double needs a room of at least 2.4m x 2.8m, so the space saving is modest for what you give up.
