Assessed from SleepSoul's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want the contouring feel of pocket springs without the price tag that usually comes with a dual-spring build. The 1000 pocket springs conform to your shape and help prevent the roll-together effect, so couples who share a bed should feel less of each other's movement. Above them, 2000 mini springs add a softer, more responsive comfort layer. The cool gel foam is a genuine plus for hot sleepers, a thin layer at 3cm, but it works with the springs' airflow rather than against it. At £349 to £529 across sizes, it sits at the affordable end for a 30cm-deep hybrid-style build.
Key Features & what's inside
- Top Layer. A 2cm pillow-top of plush filling, which means a soft, cushioned first impression before you reach the firmer support below. It takes a slight edge off the medium/firm feel.
- Cool Gel Foam. A 3cm layer of cool gel foam that slows heat build-up in the mattress. If you're a hot sleeper, this should help you stay comfortable for longer through the night.
- Pocket Springs. 1000 individual pocket springs that conform to your body's shape, supporting you where you need it most. Because each spring moves independently, they also help prevent the roll-together effect that pushes couples into the middle.
- Mini Springs. An additional 2000 mini pocket springs sit within the build for extra comfort and support. These smaller springs respond to lighter pressure, which means a more adaptive feel close to the surface.
- Base. A non-slip fabric base for additional stability. In practice this helps the mattress stay put on slatted or divan bases.

Who's it NOT for?
SleepSoul's own page mentions no sleep trial, so if you want a lengthy at-home trial with free returns, look elsewhere. The medium/firm feel may also be slightly too firm for lightweight side sleepers, even with the pillow top. And if you prefer a deep, all-foam contouring feel, a sprung build like this won't give you that.

How firm is the SleepSoul Heaven 3000 mattress?
SleepSoul describes it as medium/firm. The 2cm pillow-top and mini springs soften the surface a little, so it suits most back and combination sleepers, although lightweight side sleepers may find it slightly too firm.
Does the SleepSoul Heaven 3000 have 3000 springs?
Yes, but as a combination: 1000 full-size pocket springs provide the main support, with 2000 mini pocket springs layered in for extra comfort. Mini springs are smaller than standard pocket springs, so the feel differs from a mattress with 3000 full-size springs.
Is the SleepSoul Heaven 3000 good for hot sleepers?
It should help. A 3cm cool gel foam layer is designed to slow heat build-up, and pocket spring builds naturally allow more airflow than solid foam. Yes, the gel layer is fairly thin, but combined with the sprung core it makes this a reasonable pick if you sleep warm.
How is the SleepSoul Heaven 3000 delivered?
It arrives vacuum-sealed and packed into a box. SleepSoul says it expands to good condition within 2 hours and reaches its best after 24 hours, so it's sensible to unbox it the day before you plan to sleep on it.
What guarantee does the SleepSoul Heaven 3000 come with?
SleepSoul's own site states a 10-year guarantee. No sleep trial is mentioned on the brand's page, so check returns terms with your chosen retailer before you buy.
