Layer Details
Pillow top with knitted cover
An extra layer of comfort wrapped in a finely knitted cover. It gives the surface a softer, more cushioned feel.
Gel foam comfort layer
A breathable layer of Cool Gel foam, described as cooler than traditional memory foam, with a fresh 2cm layer of Cool Gel. That means cushioning with less heat build-up.
Pocket springs
1000 individually pocketed springs, each in its own cloth pocket, adapt to movement. Support is spread to each part of your body.

Key benefits
- Room to sprawl on your own: At 30cm wider than a UK single, you can sleep diagonally or starfish without an arm dropping off the edge.
- Fits where a double feels cramped: Being 15cm narrower than a UK double can be the margin that lets a wardrobe door or the bedroom door swing open freely.
- A softer top for one sleeper: The pillow top cushions the surface of a medium-rated mattress, which suits a solo sleeper who likes a little give without sinking deeply.
- Cooler foam near the surface: A Cool Gel foam layer sits above the 1000 pocket springs, and SleepSoul describes it as cooler than traditional memory foam.
- No flipping in a tight space: It's single-sided with turning handles, so you only need to rotate it, which is far easier than heaving a mattress over in a small room.
This size suits you if...
You sleep alone but have started to feel hemmed in by a single, or your bedroom is compact enough that a full double would crowd it. It also suits a spare room where a couple stays for the odd weekend but nobody shares every night.
Consider another size if...
You and a partner share the bed every night. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Can two adults sleep on a UK small double SleepSoul Heaven 1000?
For a night or two, yes, which makes it a sensible choice for a guest room. Nightly, it will feel tight for most couples. SleepSoul doesn't say how well this mattress isolates motion, so if one of you is a light sleeper, the UK double gives 67.5cm each for two sharing.
What size room do I need for a UK small double mattress?
We suggest at least 2.4m x 2.8m for a UK small double. That allows space to walk around the bed and open drawers. In a loft conversion with sloping ceilings, measure the floor area where you can actually stand, because the bed's edges may sit under the lowest part of the roof.
Is a small double big enough for a teenager who has outgrown a single?
For width, usually yes: it's 30cm wider than a UK single, so a growing teenager has space to turn over. Length is the same as a UK single, though, at 190cm. A tall teenager whose feet already hang off would need the UK king, which is 10cm longer; we suggest at least 2.7m x 2.9m for it.
What sheets and duvet fit a 4ft small double mattress?
Use small double (4ft) fitted sheets with a standard double duvet. At 25cm deep, this mattress needs fitted sheets with pockets deep enough to tuck well under the edges, so check the pocket depth on the packaging before you buy bedding to go with it.
Should I buy a small double or a double for a small guest room?
If couples stay only now and then and floor space is tight, the UK small double is the better fit for the room. If guests share regularly, the UK double is 15cm wider and gives 67.5cm each, though we suggest at least 2.6m x 2.8m for a UK double.
