Layer Details
Microquilted cover
A microquilted cover tops the mattress and gives it an inviting sleep surface. It is the first thing you feel, so it sets the tone for the comfort layers underneath.
Soft white fibres
Two layers of soft white fibres sit below the cover. They add cushioned comfort and extra breathability, so the surface feels softer without trapping as much warmth.
Memory foam
A layer of memory foam moulds around your shape. That gives you contouring where your body presses into the mattress.
Mirapocket springs
The core is 2000 Mirapocket springs, each encased in its own pocket. They form the base of support and respond individually, so the mattress can adapt to your shape.

Key benefits
- Real space for one: At 120cm across, this size is 30cm wider than a UK single, which means a lone adult can starfish, roll and shift position freely.
- Fits rooms a double crowds: It is 15cm narrower than a UK double, which can be the difference between a door that clears the bed frame and one that doesn't.
- A step up for teenagers: If someone has outgrown a single but the room can't spare much more floor, this 4ft width adds sleeping space without swallowing it.
- Handles the occasional guest couple: Two people can share for a weekend stay, so it suits a guest room or holiday let where nobody sleeps in it nightly.
- Standard 4ft sizing: The small double is an established UK size, so frames and fitted sheets are straightforward to find, and a standard double duvet works on top.
This size suits you if...
You sleep alone and want more width than a UK single offers, or you're furnishing a box room, loft conversion or small second bedroom where a full double would leave no walking space. It also fits if you're kitting out a guest room or rental for occasional couples rather than nightly sharing. Allow at least 2.4m x 2.8m of floor space, which is our own guidance rather than Silentnight's.
Consider another size if...
You share the bed every night, because 120cm is a snug width for two over the long term. We'd recommend the UK double instead, which is 15cm wider and the same length; allow at least 2.6m x 2.8m for that size.

FAQ's
Is a small double Mirapocket 2000 big enough for a couple?
For occasional nights, yes. Across a weekend visit or a guest room stay, two adults can share the 120cm width comfortably enough. As an every-night bed for a couple it is a squeeze, and the UK double, 15cm wider at the same length, would serve you better.
What room size do I need for the small double Mirapocket 2000?
We suggest allowing at least 2.4m x 2.8m. That's our own guidance, not Silentnight's, and it leaves enough clearance to walk round the bed and open drawers. If your room falls short of that, measure carefully before committing, as the mattress itself is 120 x 190cm.
How much wider is the small double than the single in this mattress?
The UK small double is 30cm wider than the UK single, and the two sizes are the same length at 190cm. That extra 30cm is what turns a bed you fit into a bed you can spread out in, which is the main reason solo adults size up to a 4ft.
Will the small double fit a teenager's room?
Often, yes, and it's a common upgrade for a teenager who has outgrown a UK single. In imperial terms it measures 4ft x 6ft 3in, so check the room can give up an extra 30cm of width against the single and still leave space for a desk or wardrobe doors.
