Layer Details
- 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.

- Fits the rooms most couples have: We suggest at least 2.6m x 2.8m for a UK double, so it suits many standard master bedrooms where a UK king would crowd the floor.
- Less roll-together when sharing: The 1000 individual pocket springs move independently, which means a partner turning over is less likely to tip you towards them on a narrower shared bed.
- Cooler with two bodies close together: A 3cm cool gel foam layer slows heat build-up, a slight help on a UK double where you sleep nearer each other than on a UK king.
- Stays put on the frame: The non-slip fabric base keeps the mattress from shifting on slats or a divan, handy when two people climb in from opposite sides.
- Easy bedding to find: Double sheets and a 200 x 200cm double duvet are sold almost everywhere, so dressing the bed rarely means hunting for specialist sizes.
This size suits you if...
You share a bed with your partner in a typical UK bedroom and still want bedside tables on both sides, or you're kitting out a second bedroom or first flat where the bed has to leave space for a wardrobe and drawers.
Consider another size if...
You or your partner are tall or restless, and 67.5cm each already feels tight. We'd recommend the UK king instead, provided your room allows at least 2.7m x 2.9m.

Is the SleepSoul Heaven 3000 UK double wide enough for two adults?
For most couples, yes, though it is on the cosy side at 67.5cm each for two sharing. The pocket springs reduce the dip towards the middle, which helps a narrower shared surface feel less crowded. If you often wake each other up, the UK king gives 75cm each.
Will a SleepSoul Heaven 3000 UK double fit in a small bedroom?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable once bedside tables and a wardrobe are in. The mattress measures 135 x 190cm, or 4ft 6in x 6ft 3in, so measure your floor space before ordering.
Do standard double fitted sheets fit the Heaven 3000 in a UK double?
A double fitted sheet matches the 135 x 190cm footprint, but check the pocket depth. The Heaven 3000 is 30cm deep, so a shallow sheet may ping off the corners. For the duvet, a 200 x 200cm double gives enough overhang for two people sharing.
How much bigger is the Heaven 3000 UK king than the UK double?
The UK king is 15cm wider and 10cm longer, giving two sharers 7.5cm more each. That extra length suits taller sleepers. The trade-off is floor space: we suggest at least 2.7m x 2.9m for a UK king, against 2.6m x 2.8m for a UK double.
Is a UK double Heaven 3000 a good choice for a guest room?
It suits a guest room where visiting couples stay, because a UK double sleeps two without swallowing a smaller spare room. The medium firm feel suits most guests, although lightweight side sleepers may find it a little firm. Compare the retailers listed on this page, as prices shown here update as retailers change them.
