Why should you choose this mattress?
The pillow top adds a plush, cushioned surface, so the mattress feels softer on top than its medium firm rating suggests. Beneath it, a 3cm CoolGel layer contours gently to your body and is designed to disperse heat, which helps if you tend to sleep warm. The pocket spring core uses individually pocketed springs, with mini pocket springs alongside, for a supportive base. It suits most back and side sleepers who like a little give, although heavier sleepers may want to check how it feels for them. It's single-sided, so you rotate it head to toe rather than flip it, and turning handles make that easier.
Key features & layer details
Pillow top
A plush pillow top with 2cm of soft foam beneath the surface. It gives a cushioned, softer-feeling top without changing the medium firm rating.
CoolGel foam
A 3cm CoolGel layer that contours gently to your body and disperses heat. That means pressure-relieving comfort with less heat build-up.
Pocket spring core
1000 individually pocketed springs with up to 2000 mini pocket springs. Each spring moves on its own, which gives a supportive base that follows your shape.

Best suited for?
Side sleepers
The plush pillow top and a 3cm CoolGel layer that contours gently to your body give a cushioned surface with a little give.
Back sleepers
Individually pocketed springs with mini pocket springs alongside make a supportive base, while the pillow top adds a softer, cushioned feel on the surface.
Warm sleepers
A 3cm CoolGel layer is designed to disperse heat, which means less heat build-up through the night if you tend to sleep warm.
If you prefer sleeping on a very firm mattress, this might not be the best choice. It's rated medium firm, and the pillow top adds a softer, cushioned feel on the surface. It's also single-sided, so you can rotate it head to toe but not flip it. Anyone wanting a flat, unyielding surface may find the top gives more than they'd like.
Save on an earlier or ex-display model

FAQ's
How firm is the SleepSoul Heaven Cool Gel 3000 Pocket Pillowtop?
It's rated medium firm. The pillow top adds a plusher feel on the surface, so it should feel a little softer at first, with medium firm support underneath. Anyone wanting a very firm bed may find it too cushioned.
What sizes does the SleepSoul Heaven Cool Gel 3000 Pocket Pillowtop come in?
It comes in a UK single, UK double, UK king and UK super king. A UK small single and a UK small double aren't listed.
How deep is the SleepSoul Heaven Cool Gel 3000 Pocket Pillowtop?
It's 30cm deep. That's a fairly substantial mattress, so check your bed frame and fitted sheets suit that depth before you buy.
Is the SleepSoul Heaven Cool Gel 3000 Pocket Pillowtop good for hot sleepers?
It may help a little. The CoolGel foam layer is designed to disperse heat, which should suit people who sleep warm. A pillow top still adds cushioning, so very hot sleepers may want to weigh that up.
Does the SleepSoul Heaven Cool Gel 3000 Pocket Pillowtop have a trial or guarantee?
Mattress Online offers a 100-night trial, which is the retailer's own offer. SleepSoul gives a 10-year guarantee. Check the retailer's terms for how returns work before you order.
