Layer Details
Pillow top
A 2cm layer of soft foam in the microquilted surface. It gives the top a softer, more cushioned feel without changing the medium to firm rating.
Cool Gel foam
A 3cm Cool Gel foam layer under the pillow top that contours to the body. It also helps disperse heat, so you get shaping with less warmth.
Pocket spring core
1000 individually pocketed springs, with 2000 mini pocket springs added for bounce and comfort. The mini springs reduce motion transfer, so you're less likely to feel a partner move.

Key benefits
- Fits an ordinary bedroom: We suggest a room of at least 2.6m x 2.8m, which means many standard master bedrooms can take the UK double with bedside tables on both sides.
- Fewer wake-ups at close quarters: You lie near each other on a UK double, so mini pocket springs that SleepSoul says limit motion transfer help when one of you turns over at night.
- Help with shared body heat: Two people on a UK double generate more warmth, and the 3cm Cool Gel foam layer is designed to disperse heat, which should suit couples who run warm.
- Bedding is easy to find: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, which helps if you're kitting out a first flat on a stretched budget.
- A sensible guest bed: The medium firm support under a softer pillow top suits most visiting back and combination sleepers, although very light side sleepers may want more give.
This size suits you if...
You share the bed with a partner and your room is close to our suggested 2.6m x 2.8m minimum, or you're furnishing a spare room where visiting couples need a proper shared bed. It also fits a solo sleeper who likes room to spread out while a dog or cat claims one corner.
Consider another size if...
You both sleep spread out, or one of you is tall and wants extra length. We'd recommend the UK king instead: it is 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is the SleepSoul Heaven 3000 UK double big enough for two people?
For most couples, yes. The UK double gives you 67.5cm each, which feels close but workable if you both sleep fairly still. If you want more personal space, the UK king gives 75cm each, so the UK double gives 7.5cm less per person.
What size bedroom do I need for a SleepSoul Heaven 3000 double?
We suggest at least 2.6m x 2.8m for the UK double, with around 3m x 3m feeling comfortable. In a smaller second bedroom shared with a wardrobe and drawers, measure walkways on both sides before you commit, especially if you want bedside tables.
SleepSoul Heaven 3000 double or king: which should a couple choose?
Choose the UK double if your room is tight or you rarely disturb each other. The UK king is 15cm wider and 10cm longer, but we suggest at least 2.7m x 2.9m for it, so it can crowd a typical bedroom.
Will I feel my partner move on the SleepSoul Heaven 3000 in a double?
Sharing a UK double puts you nearer each other than on larger sizes, so movement is more likely to reach you. SleepSoul says the 2000 mini pocket springs reduce motion transfer, which should soften that effect, though restless sleepers may still prefer the extra width of a UK king.
What are the SleepSoul Heaven 3000 UK double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm, and the mattress is 30cm deep. Standard double fitted sheets suit the length and width, but check the pocket depth on the label so the sheets cover the 30cm comfortably.
