Layer Details
Top Layer
A cashmere knitted fabric that feels soft and slightly plush the moment you lie down. It's breathable too, which helps stop heat building up at the surface.
Memory Foam
3cm of memory foam that moulds to your shape, which means pressure points like hips and shoulders get gentle relief. It's a modest layer, so you get contouring without the stuck-in-the-mattress feeling deeper memory foam can create.
High-Density Foam
A 3cm layer of high-density foam that responds as you move. This makes changing position easier than on all-memory-foam designs.
Soft Foam
2cm of softer foam adds a touch of extra cushioning between you and the springs. It's there to keep the medium feel from tipping into firmness.
Springs
1000 pocket springs work alongside 2000 mini springs, giving targeted support across the whole mattress. Because each spring moves independently, your partner's movement is less likely to travel across the bed.

Key benefits
- Leaves room for furniture: We suggest a room of at least 2.6m x 2.8m, so a second bedroom or first flat can usually take the bed alongside a wardrobe and a chest of drawers.
- Calmer sharing at close quarters: With 67.5cm each for two sharing, the independently moving pocket springs help more here, which means a partner turning over is less likely to jolt you awake.
- A safe pick for a guest room: The medium feel sits between firm and soft, which suits a spare room where visiting couples arrive with sleep preferences you can't predict.
- Space for one plus a pet: If you sleep alone, the UK double lets a dog or cat settle at the foot or in a corner without leaving you clinging to the edge.
- Simple to dress: Double bedding is easy to find, although the 36cm depth means you'll need deep fitted sheets rather than standard ones.
This size suits you if...
You share with a partner in a typical UK bedroom and still want space for bedside tables and a wardrobe, or you sleep alone and like room to stretch out, perhaps with a dog or cat taking a corner.
Consider another size if...
Either of you is tall, you both like to sprawl, and your bedroom can take a bigger bed. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for the UK king.

FAQ's
Will the SleepSoul Space 3000 UK double fit in a small bedroom?
We suggest at least 2.6m x 2.8m for the UK double, with around 3m x 3m feeling comfortable. If your room is tighter than our suggested minimum, SleepSoul doesn't make this model in a UK small double or UK single, so the UK double is as compact as the Space 3000 gets.
How much space does each person get on a SleepSoul Space 3000 double?
Two people sharing get 67.5cm each on the UK double. The UK king gives 75cm each, so the UK double gives 7.5cm less each. For most couples that is comfortable, although if one of you sleeps like a starfish you'll feel the difference.
Is the SleepSoul Space 3000 double long enough for tall people?
The UK double is 190cm long, or 6ft 3in. The UK double is 10cm shorter than the UK king, so if either of you is tall enough for your feet to reach the end, the UK king is the better fit.
Can I fit bedside tables either side of a SleepSoul Space 3000 double?
In a room at our suggested minimum of 2.6m x 2.8m, bedside tables on both sides will feel snug. Around 3m x 3m gives you room for tables and space to walk round the bed, which matters in a shared bedroom where you both get up at different times.
What sheets fit a SleepSoul Space 3000 UK double?
You'll need deep fitted double sheets, because the mattress is 36cm deep and standard fitted sheets may pull off at the corners. For the duvet, a 200 x 200cm double duvet suits the UK double footprint.
