Assessed from SleepSoul's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is the hybrid construction at a mid-range price. The 3cm of memory foam contours to your body, which means pressure at your hips and shoulders is eased before the springs take over the supportive work. Underneath, 1000 pocket springs move independently, so a restless partner is less likely to disturb you, and the 2000 mini springs add a second tier of responsiveness. The cashmere knitted cover is a genuinely premium touch at this price and keeps the surface breathable. At 36cm deep it has real presence on a bed frame, with the caveat that you'll need deep fitted sheets. The 10-year guarantee is reassuring for a purchase in this bracket.
Key Features & what's inside
- 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.

Who's it NOT for?
There's no Single or Small Double, so it won't work for a child's room or a compact spare bed. If you prefer a distinctly firm or distinctly soft feel, this medium tension may sit awkwardly in the middle for you. Heavier sleepers wanting very deep foam layers may find the comfort layers a little shallow.

How firm is the SleepSoul Space 3000 mattress?
SleepSoul describes it as medium. In practice that means a balanced feel: the memory foam and soft foam layers give initial cushioning, while the pocket springs beneath keep you supported. It suits back and side sleepers who want neither extreme, although fans of a very firm surface should look elsewhere.
How many springs does the SleepSoul Space 3000 have?
3000 in total, made up of 1000 full-size pocket springs and 2000 mini springs. The mini springs add a second layer of responsiveness on top of the main support unit, which means the mattress adjusts more precisely to different parts of your body.
Does the SleepSoul Space 3000 come in a box?
Yes, it arrives vacuum sealed and boxed. SleepSoul says it expands to good condition within 2 hours and reaches its best after 24 hours, so it's sensible to let it settle for a full day before judging the feel.
What sizes does the SleepSoul Space 3000 come in?
UK Double, King and Super King, priced from £505 to £605. There's no Single or Small Double option, which is a shame for smaller rooms. At 36cm deep, you'll also want deep fitted sheets in whichever size you choose.
Does the SleepSoul Space 3000 have a guarantee?
Yes, SleepSoul's product page lists a 10-year guarantee, which is a reasonable span for a mattress at this price. As with any guarantee, check the terms at the point of purchase for what it covers.
