Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this one if you want hybrid comfort on a budget without giving up cooling features. The pocket springs adapt to your movement individually, which means your partner's tossing is less likely to travel across the bed, while the pillow top adds a slightly plusher feel than the price suggests. SleepSoul describes it as medium, so it suits most sleepers, although anyone who prefers a properly firm surface should look elsewhere. Mattress Online lists a 100-night trial and free delivery to most locations, with next-day and chosen-day options, so you can try it at home with little risk. Yes, it's a budget mattress, but the Which? Best Buy endorsement and 10-year warranty give it credibility beyond its price.
Key Features & what's inside
- Knitted cover. A soft knitted top layer that adds cosiness and warmth. Knitted covers are breathable, which means heat can escape rather than build up under you.
- Pillow top. An extra layer of padding sewn on top, which means a slightly more luxurious, cushioned feel when you first lie down.
- Cool Gel. A 2cm gel layer that responds to your body temperature and gently contours to your shape. It's designed to help prevent overheating through the night.
- Gel Foam. Gel-infused foam that sleeps cooler than traditional memory foam. It cushions pressure points, which can help soothe aches and pains.
- Pocket Springs. Individual springs encased in cloth pockets that move independently. This means each part of your body gets support where it needs it, and movement is less likely to disturb a partner.

Who's it NOT for?
If you prefer a firm mattress, this one's medium feel may be softer than you'd like, particularly if you're a heavier back or stomach sleeper who needs more pushback. And if you want an all-foam feel with deep sink-in contouring, a spring-based hybrid like this won't give you that.

Is the SleepSoul Heaven 1000 firm or medium?
SleepSoul lists it as medium, although some retailer listings describe it as medium firm. In practice that means a balanced feel: enough give for side sleepers to settle into, with pocket springs underneath providing support. Lightweight sleepers may find it a touch firmer than expected, as is often the case with hybrids.
Does the SleepSoul Heaven 1000 come with a trial?
Mattress Online, the retailer listing this mattress, offers a 100-night trial. That's the retailer's own offer rather than a SleepSoul guarantee, so if you buy elsewhere, check that seller's returns terms before ordering.
How long is the warranty on the SleepSoul Heaven 1000?
There's a 10-year warranty provided by SleepSoul, but it requires registration within 30 days of purchase on the SleepSoul website. Set a reminder when it arrives, as it's an easy step to forget.
Is the SleepSoul Heaven 1000 good for hot sleepers?
It's built with cooling in mind. The 2cm Cool Gel layer responds to your temperature, the gel foam sleeps cooler than traditional memory foam, and the knitted cover is breathable. Pocket springs also allow more airflow than a solid foam base, so hot sleepers are reasonably well served here.
How deep is the SleepSoul Heaven 1000 mattress?
It's 25cm deep, which includes the pillow top layer. That's a fairly standard depth, so most fitted sheets for regular mattresses should fit without any trouble.
