Why should you choose this mattress?
The pillow top and gel foam layers add cushioning over the springs, so the surface feels softer than the medium rating alone suggests. The gel foam has cooling properties and the knitted cover is breathable, which helps if you tend to sleep warm. The 1000 individually pocketed springs sit in cloth sleeves, so each one moves on its own. Because it arrives vacuum-packed in a box, it's easier to get upstairs and into tight rooms. It should suit most back and side sleepers, although heavier sleepers who like a very firm feel may want more support.
Key features & layer details
Cover
A soft quilted or stretch knit cover, described as a breathable knit. It's the first thing you feel, and it helps air move through the surface.
CoolGel foam
A 2cm layer of CoolGel foam within the quilting. It adds cushioning and has cooling properties, so the surface feels softer without trapping as much heat.
CoolGel foam
A second 2cm layer of CoolGel foam. Together with the first it builds the pillow top feel and gives more give under your shoulders and hips.
Memory/support foam
A 1cm layer of foam, described as memory or support foam. It sits between the gel and the springs, so the comfort layers don't feel the springs underneath.
Pocket springs
1000 individually pocketed springs in cloth sleeves, with a foundation layer beneath. Each spring moves on its own, so the mattress responds to your body and gives steady support.

Best suited for?
Side sleepers
Two 2cm layers of CoolGel foam under the pillow top give extra cushioning under the shoulders and hips, so the surface feels softer where side sleepers press in.
Back sleepers
The 1000 individually pocketed springs each move on their own, so the mattress responds to your body and gives steady support under a medium feel.
Warm sleepers
Cooling CoolGel foam and a breathable knitted cover let air move through the surface, so it traps less heat overnight than a heavily padded top.
Guest rooms
Arriving vacuum-packed and rolled in a box makes it easier to carry upstairs and into tight rooms, which suits a spare bedroom.
If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated medium, and the pillow top adds cushioning that can feel softer still. You also can't flip it, as it's single-sided with turning handles, so you're limited to rotating it.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the SleepSoul Heaven Gel Pocket 1000?
It's rated medium. The pillow top and gel foam layers add cushioning on the surface, so it can feel a little softer at first, but anyone wanting a properly firm mattress will probably find it too plush.
What sizes does the SleepSoul Heaven Gel Pocket 1000 come in?
It comes in a UK single, UK small double, UK double, UK king and UK super king. Check your bed frame measurements first, as the UK king and UK super king are 200cm long.
How deep is the SleepSoul Heaven Gel Pocket 1000?
It's 25cm deep. That's enough for a pillow top, gel foam layers and a bed of pocket springs, and it should sit comfortably on most standard bed frames.
Is the SleepSoul Heaven Gel Pocket 1000 good for hot sleepers?
It has some features aimed at heat, including gel foam with cooling properties and a knitted breathable cover. That should help warm sleepers, though the pillow top and foam layers mean it may not sleep as cool as an open spring design.
Can you flip the SleepSoul Heaven Gel Pocket 1000?
No, it's single-sided, so flipping isn't an option. It does have turning handles, which makes it easier to rotate the mattress from time to time to help wear evenly.
