Layer Details
- Pillow Top. An extra layer of plush fillings sewn onto the surface, which means a softer, more cushioned first impression when you lie down. It gives the medium firm core a gentler feel on pressure points like hips and shoulders.
- Cool Gel Memory Foam. This foam contours to your body for pressure relief and support, while the gel helps regulate body temperature better than standard memory foam. In practice, you get the hug of memory foam with less of the heat build-up.
- Pocket Springs. Each spring sits in its own fabric pocket and moves independently, which means the mattress responds to your body shape rather than pushing back as one unit. That independence also helps reduce disturbance when a partner moves.

- Room left for the rest of your furniture: We suggest a room of at least 2.6m x 2.8m, which means most master bedrooms keep space for bedside tables on both sides and a clear path around the bed.
- Less disturbance in a shared space: On a UK double you each have 67.5cm, so the individually pocketed springs matter: a partner turning over is less likely to jolt your side.
- Two sleepers, a slightly cooler surface: Sharing a UK double puts two bodies close together, and the cool gel memory foam handles heat a little better than standard memory foam, useful if either of you runs warm.
- A comfortable guest bed for visiting couples: The medium firm feel and cushioned pillow top suit most sleepers, so friends staying for a weekend are unlikely to find the UK double too hard or too soft.
- Easy to dress: Double sheets fit the UK double, along with a 200 x 200cm double duvet, and both are widely stocked, which keeps things simple when you're furnishing several rooms at once.
This size suits you if...
You share a bed in a typical UK bedroom and want a hybrid that still leaves room for bedside tables, or you're kitting out a guest room for visiting couples, or you sleep alone and like enough width for a dog or cat to claim a corner.
Consider another size if...
You're both tall or like plenty of personal space, as the UK double is 10cm shorter and 15cm narrower than the UK king. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m.

How much space does each person get on a SleepSoul Wish 3000 UK double?
Two people sharing the UK double get 67.5cm each. That suits most couples, although it feels snug if one of you sprawls. The UK king gives 75cm each, so the UK double gives 7.5cm less per person. The pocket springs move independently, which helps keep a partner's movement from travelling across to your side.
Will a SleepSoul Wish 3000 UK double fit a small bedroom?
We suggest a room of at least 2.6m x 2.8m for the UK double, with around 3m x 3m more comfortable if you want bedside tables and a wardrobe too. If your room is tighter than 2.6m x 2.8m, the UK small double needs at least 2.4m x 2.8m and is the same length.
Is it worth sizing up the SleepSoul Wish 3000 from a UK double to a UK king?
If you're tall or disturb each other at night, the UK king is 15cm wider and 10cm longer than the UK double. It needs a larger room, though: we suggest at least 2.7m x 2.9m. If your bedroom sits nearer 2.6m x 2.8m, the UK double keeps the room usable.
Does the SleepSoul Wish 3000 UK double sleep warm with two people?
Two sleepers on the UK double lie closer together than on a UK king, so shared body heat builds a little more. The cool gel memory foam copes with heat better than standard memory foam, which helps, but a very hot sleeper sharing with a partner may prefer the extra width of a bigger size.
Is the SleepSoul Wish 3000 in a UK double a good guest room mattress?
For a guest room that hosts visiting couples, the UK double is a sensible fit: 67.5cm each is fine for a few nights, and the medium firm feel with a pillow top suits most sleepers. If guests are usually on their own, the UK single needs a smaller room, at least 2.1m x 2.8m.
