Layer Details
Sleep surface
A naturally hypoallergenic fabric that's soft against the skin. A gentle starting point, particularly if allergies bother you at night.
Comfort Breathe®
These fibres are 15x more breathable than standard memory foam, which means air moves through rather than trapping heat. If you're a hot sleeper, this is the layer doing the heavy lifting.
2000 Mirapocket springs
Each spring sits in its own pocket and responds independently to your movements. That gives zoned support and better spinal alignment, and it limits motion transfer between partners.
Protective Layer
This layer disperses pressure from the spring unit across the mattress. In practice, that should help the mattress last longer before it starts to sag.
Durable case
A soft, hardwearing outer case designed to keep the mattress comfortable for years to come.

Key benefits
- Room to spread out alone: At 120cm wide you can shift position freely through the night, which matters more here because the 2000 Mirapocket springs respond wherever your weight lands.
- Fits rooms a double would crowd: It's 15cm narrower than a UK double, often the difference between a door that clears the bed frame and one that doesn't.
- Cooler nights in a smaller room: Compact bedrooms can hold heat, and the Comfort Breathe fibre layer moves warmth away from your body rather than trapping it beneath you.
- Copes with the occasional guest: Two people can share a small double for a night or two, and the independent pocket springs limit how much you feel each other move.
- Easy to dress and frame: 4ft is a standard UK size, so small double fitted sheets and frames are simple to find, and a standard double duvet drapes generously over it.
This size suits you if...
You sleep alone most nights and have outgrown a UK single, perhaps a teenager whose room can't spare more floor space, or you're furnishing a box room, loft conversion or studio where a UK double leaves no walking room. It also fits a guest room or holiday let where couples stay occasionally rather than nightly, and where you'd rather they slept cool than complained about a stuffy spare room.
Consider another size if...
You share the bed every night, or your room comfortably clears 2.6m x 2.8m and you'd value the extra width. We'd recommend the UK double instead, which is 15cm wider and the same length.

FAQ's
Is a small double Silentnight Comfort Breathe 2000 big enough for a couple?
For occasional nights, yes. Two adults can share 120cm of width, and the 2000 Mirapocket springs keep one person's movements from disturbing the other. As an every-night bed for two it's a squeeze, though. Couples sharing full time should look at the UK double, which adds 15cm of width.
What room size do I need for the small double Comfort Breathe 2000?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open drawers or a wardrobe without shuffling sideways. The mattress itself is 120 x 190cm, so measure your room, mark the footprint out on the floor and check the door still swings clear.
How much wider is the small double than a single in this mattress?
The UK small double is 30cm wider than the UK single, and both are 190cm long. That extra width is what lets an adult, or a teenager who has outgrown a single, roll over and stretch out properly. It's a noticeable upgrade for solo sleeping without moving up to a full double footprint.
What bedding fits the Silentnight Comfort Breathe 2000 small double?
You'll need small double, 4ft, fitted sheets so the corners actually grip, and at 31cm deep this mattress needs deep-fitted versions. For the top layer, a standard double duvet works well and hangs generously over the sides. Both are standard UK sizes, so you won't be hunting specialist stockists.
Is the small double Comfort Breathe 2000 good for a guest room?
It suits one well. The footprint fits compact spare rooms, solo guests get generous space, and visiting couples can share for a few nights. The naturally hypoallergenic sleep surface is a quiet bonus for guests with sensitivities, and the breathable fibre layer helps in spare rooms that run warm.
