Assessed from the specification published by MattressNextDay, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress suits sleepers who want a softer, cushioned surface without giving up spring support. The pillow top gives an immediate plush feel, the memory foam layer beneath contours to your body, and the pocket springs move independently, which means your partner turning over is less likely to wake you. The Medium firmness works for most sleeping positions, although side sleepers in particular tend to get on well with this kind of layered comfort. Mattressnextday lists a 10-year guarantee and free next day delivery to mainland UK, though some addresses may incur a small fee. If you're on a tight budget but wary of thin foam-only mattresses, this is a sensible middle ground.
Key Features & what's inside
- Pillow Top. An extra layer of plush filling sewn onto the surface, which means a soft, cushioned feel the moment you lie down. It's the layer that gives the mattress its cloud-like first impression.
- Memory Foam. Memory foam moulds to your body, which means pressure points like hips and shoulders get cradled rather than pushed against. It also adds a supportive, contouring quality beneath the softer top.
- Pocket Springs. The King size contains 800 individually pocketed springs, each in its own fabric pocket so they move independently. In practice that means better motion isolation and support that responds to where you actually need it.

Who's it NOT for?
If you prefer a firm, supportive surface, the Medium feel and plush pillow top may be too soft for you. Memory foam can also hold warmth, so very hot sleepers might want a breathable alternative. And note that no sleep trial is mentioned on the retailer listing, which matters if you like a safety net.
SleepSoul Cloud 800 Pocket Memory Mattress

How firm is the SleepSoul Cloud 800 mattress?
It's listed as Medium. The pillow top and memory foam give it a soft, cushioned surface feel, while the pocket springs underneath provide the underlying support, so it sits comfortably in the middle of the firmness scale.
How many springs does the SleepSoul Cloud 800 have?
The King size contains 800 individually pocketed springs. Spring count varies by size, so smaller sizes will have fewer. Each spring sits in its own fabric pocket and moves independently, which helps reduce motion transfer between partners.
Does the SleepSoul Cloud 800 come with a guarantee?
Mattressnextday, the retailer listing this mattress, states a 10-year guarantee. Because this term appears on the retailer's page rather than the brand's own site, it's worth confirming the guarantee with whichever retailer you buy from.
Is the SleepSoul Cloud 800 hypoallergenic?
Yes. The listing states it's hypoallergenic and vegan friendly, and it meets the BS7177: 2008 fire resistance standard (Low Hazard). That makes it a reasonable pick if you're sensitive to allergens or avoiding animal-derived materials.
How deep is the SleepSoul Cloud 800 mattress?
It's 32cm deep, which is a generous depth at this price and reflects the layered build: pillow top, memory foam and pocket springs. Check your fitted sheets will stretch to a deeper mattress before it arrives.
