Assessed from the specification published by Mattress Man, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is the spring count. With 4,000 pocket springs, you get finer contouring than a basic sprung mattress can manage, which means better pressure relief along your hips and shoulders and less disturbance when a partner moves. The orthopaedic label suggests it's aimed at people who want firmer support, perhaps for a bad back or simply a preference for a sturdier surface. The lack of published layer details is frustrating for a considered purchase. But at £579 to £695, that spring count comes in at a fairly sensible price, and buying through Mattressman adds a 60-night trial so you can change your mind if the feel isn't right.
Key Features & what's inside
Awaiting up to date specifications. Please check back later.
Who's it NOT for?
Orthopaedic mattresses generally sit on the firmer side, so lightweight side sleepers may find it a little too solid for comfortable pressure relief. There's no Single size listed, which rules it out for children's rooms or narrow guest beds. And if you want full transparency on materials and construction, the published information here is sparse.

How many springs does the SleepSoul Space 4000 have?
It contains 4,000 pocket springs. Each spring is sewn into its own fabric pocket and moves independently, which means the mattress can follow the shape of your body more closely and limit motion transfer between partners.
How much does the SleepSoul Space 4000 cost?
Prices range from £579 to £695 depending on size, starting at £579. It comes in UK Double, King and Super King.
Does the SleepSoul Space 4000 come with a sleep trial?
Mattressman lists a 60-night trial on this mattress. That trial is the retailer's own offer rather than a manufacturer guarantee, so if you buy elsewhere the terms may differ. Check with your chosen retailer before ordering.
How quickly can the SleepSoul Space 4000 be delivered?
Mattressman offers free next day delivery on this mattress, with a handling time of 0 to 1 day and transit time of 1 to 3 days. These are the retailer's own delivery terms, so they apply when buying through Mattressman specifically.
Is the SleepSoul Space 4000 firm?
Neither the brand nor the retailer publishes a firmness rating for this mattress. It's marketed as orthopaedic, a term that typically signals a firmer, more supportive feel, but without an official statement we can't confirm exactly where it sits. If firmness matters to you, it's worth checking with the retailer directly.
