Layer Details
- Fits almost any room: At 90cm wide, this size leaves floor space for a desk, wardrobe and toy storage in even a compact child's bedroom.
- Works for shared rooms: Two UK singles plus a walkway will fit where one larger bed dominates, which suits siblings sharing a room.
- Pocket spring support for growing sleepers: The Mirapocket 1000 springs adjust to the individual, which means a light teenager gets contouring rather than a rigid, one-note surface.
- Spare rooms that do two jobs: A UK single in a room that doubles as an office keeps the space usable by day and guest-ready by night.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and both are the most widely stocked and affordable bedding of any size.
This size suits you if...
You're buying for a child or teenager and want a recognised UK brand under them, or you're a single adult in a first flat or student room where the frame came with the tenancy but the mattress didn't. It also suits a spare room or loft conversion where 90cm of width is genuinely all the floor plan allows. Allow at least 2.1m x 2.8m of floor space.
Consider another size if...
You're an adult who shares the bed, or you simply want more stretching room than 90cm allows. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m for it.

Will the Mirapocket 1000 UK single fit a bunk or mid sleeper frame?
The width and length, 90 x 190cm, match standard UK bunk and mid-sleeper frames. The catch is depth: raised frames often have a maximum mattress depth for safety rail clearance, and Silentnight doesn't publish a depth we can confirm for this model. Check the depth on the retailer listing against your frame's limit before you buy.
Is the UK single Mirapocket 1000 suitable for a child?
Yes, the UK single is the standard children's size, and pocket springs give a lighter body proper contouring rather than a board-flat feel. One caveat: we can't confirm this model's firmness rating, so if your child needs a specific feel, check the retailer listing first. At 190cm long, it will last well beyond the teenage years.
Is a UK single big enough for an adult?
For one adult, yes. At 90cm wide you get the full width to yourself, which is more personal space than each half of a shared UK double provides. Taller sleepers should note the 190cm length: if you're over 6ft 3in, the UK king version of this mattress runs 10cm longer.
Would two singles work better than one double in a guest room?
Often, yes. Two UK singles give visiting friends or grandchildren their own beds, and the independent pocket springs mean each mattress supports its sleeper without compromise. You'll need roughly double the width of a single-bed layout, so measure carefully. Pushed together, two singles also approximate a larger bed when a couple visits.
What size room do I need for a UK single mattress?
We suggest at least 2.1m x 2.8m of floor space, which allows room to walk around the bed and open drawers or a wardrobe. That makes this size a sensible pick for box rooms and loft conversions, where the 90cm footprint can sit under a sloping ceiling and still leave the standing-height area free.
