Layer Details
Soft foam top layer
A 1cm layer of soft foam with airflow built in, which helps it contour to your body without trapping heat. It gives the surface a gentle first feel.
Coolgel layer
A 3.5cm layer of Coolgel foam designed to slow heat build-up in the mattress. If you sleep warm, it should help you stay cooler for longer.
Memory foam layer
A 3.5cm memory foam layer that acts as a transition between the comfort layers and the springs. It adds some sink and keeps movement down.
Mini pocket springs
An extra set of 1000 mini pocket springs sits above the main springs. They add comfort and support in the middle of the mattress.
Pocket springs
1000 pocket springs that move individually, so they follow your body's shape and support you where you need it. This also stops the roll-together effect if you share the bed.
Soft foam base layer
A 2cm layer of soft foam that spreads your weight evenly. That adds deeper comfort and stops the springs feeling too prominent.
Non-slip fabric base
An anti-slip fabric underneath helps the mattress stay put on your bed base. It gives extra stability, so you shouldn't find it shifting about.

Key benefits
- Room to spread out alone: The UK small double is 30cm wider than a UK single, which means you can lie diagonally or sleep starfish without an arm dropping off the edge.
- Quieter nights when someone stays: Each pocket spring moves independently, so when a partner stays over you feel less of their turning than you would on a traditional open coil.
- Fits a tighter room: Being 15cm narrower than a UK double can decide whether the bedroom door swings clear of the bed or catches on the corner.
- Level support for back and front sleepers: The medium firm hybrid feel keeps hips from sinking, although lighter side sleepers may find this UK small double slightly firm.
- Easy to find frames and bedding for: The 4ft UK small double is a standard UK size, which means frames and fitted sheets for this mattress are straightforward to buy.

Consider another size if...

FAQ's
Is the SleepSoul Cool Gel 2000 small double big enough for two people?
For occasional nights, yes, though it's snug. The UK small double is 15cm narrower than a UK double, which itself gives 67.5cm each for two sharing, so a couple sleeping together nightly will feel the squeeze. The pocket springs help a little, since each moves independently and you feel less of a partner turning over.
Does the SleepSoul Premium Cool Gel 2000 come in a double or king size?
SleepSoul currently lists this mattress in the UK small double only. If you need a UK double or UK king for nightly sharing, you'll have to look at a different mattress. Compare the retailers listed on this page for the latest availability, as listings are updated when retailers change them.
What size bedroom do I need for a SleepSoul Cool Gel 2000 small double?
We suggest allowing at least 2.4m x 2.8m for a UK small double. In a loft conversion, measure the floor where you can actually stand, not the full footprint, because sloping ceilings make the edges of the room hard to use for getting in and out of bed.
Will the SleepSoul small double fit a 4ft bed frame?
It should. The UK small double measures 120 x 190cm, which is 4ft x 6ft 3in, the standard 4ft size. Measure inside the frame before ordering rather than relying on the label alone, so you know the mattress will sit snugly without gaps at the sides.
Is a SleepSoul Cool Gel 2000 small double good for a teenager?
Often, yes, if they've outgrown a UK single. The UK small double is 30cm wider but the same length, so it adds width without eating into the room's length. Medium firm suits back and front sleepers well, although a lighter teenager who sleeps on their side may find it slightly firm.
