Layer Details
Soft Foam
A breathable top layer with airflow designed to avoid heat build-up. It contours to your body, which means less pressure on hips and shoulders.
Coolgel
Temperature-regulating gel that slows heat build-up in the mattress. In practice, that means you should sleep cooler for longer through the night.
Memory Foam
A transition layer that allows a controlled amount of sink. It also minimises movement, helpful if you share the bed.
Pocket Springs
1000 individual pocket springs conform to your body's shape, supporting you where you need it most. They also prevent the roll-together effect that can pull couples into the middle.
Soft Foam
A lower comfort layer that spreads your weight consistently. This gives the mattress a settled, even feel across its surface.
Non slip base
An anti-slip base that adds stability, so the mattress stays put on your bed frame.

Key benefits
- Room to stretch out on your own: Being 30cm wider than a UK single, it lets you shift position through the night without finding the edge under your elbow.
- Fits a compact bedroom: At 15cm narrower than a UK double, it can leave you enough clearance for a door swing or wardrobe, and we suggest allowing at least 2.4m x 2.8m.
- Cooler sleep in a small room: A small bedroom can feel stuffy, and the Coolgel layer slows heat build-up in the mattress, which means you should stay comfortable for longer before feeling warm.
- Manageable for weekend guests: For a guest room where a couple stays now and then, the pocket springs limit roll-together and the memory foam layer dampens movement, so a short visit is comfortable enough.
- Easier to place under a sloping ceiling: In a loft conversion, the 4ft width makes it simpler to find a spot where you can still stand upright beside the bed.
This size suits you if...
You sleep alone and want more room than a single gives, your bedroom is too tight for a full double, or you're furnishing a guest room where a couple stays only the occasional night.
Consider another size if...
You share the bed with a partner every night and want space to yourselves. We'd recommend the UK super king instead, which gives 90cm each for two sharing; we suggest at least 3m x 2.9m for the UK super king.

FAQ's
Is the SleepSoul Cool Gel 1000 small double a good upgrade for a teenager?
For a teenager who has outgrown a single, yes. The UK small double is 30cm wider than a UK single but the same length, so it adds width without eating much more floor. The firm feel suits back and front sleepers well, although a slim teenager who sleeps on their side may find it a little too firm.
Will the SleepSoul Cool Gel small double fit in a box room?
It has a better chance than a UK double, being 15cm narrower, which can make the difference between a door that clears and one that catches. We suggest allowing at least 2.4m x 2.8m for a UK small double. Measure the door swing and any wardrobe doors before you order.
Is the SleepSoul Cool Gel small double OK for a couple at weekends?
For the occasional night, yes. The pocket springs help stop you both rolling into the middle, and the memory foam layer cuts down movement when one of you turns over. For every night, the UK super king is the better choice, giving 90cm each for two sharing.
SleepSoul Cool Gel 1000 small double or super king: which should I buy?
It comes down to who sleeps in it and how much floor you have. The UK small double is 60cm narrower and 10cm shorter than the UK super king. We suggest at least 2.4m x 2.8m for the UK small double and at least 3m x 2.9m for the UK super king.
What size is the SleepSoul Cool Gel 1000 small double in feet?
It measures 4ft x 6ft 3in, or 120 x 190cm. A 4ft bed is a standard UK size, so you shouldn't struggle to find a frame or divan to put it on. Buy fitted sheets labelled small double (4ft) so the corners sit snugly.
