Layer Details
- Cover. A knitted, microquilted soft-touch cover, which means a slightly cushioned, cosy surface the moment you lie down. It's designed for enhanced airflow and breathability, so warmth doesn't build up against your skin.
- Comfort Layer. Eco Comfort Fibre fillings that are 100% sustainable and made from recycled materials. They offer cooling and breathability, so you get cushioning without the heat retention some foams can bring.
- Support System. 1000 individual Mirapocket springs, each encased in its own fabric pocket and strengthened by polyester walls. Because each spring responds independently to your body shape, you get pressure relief where you sink and support where you don't.

- Fits where other sizes won't: At 3ft x 6ft 3in, this size slots into box rooms, loft conversions with a narrow footprint, and rooms where the bed shares space with a desk and wardrobe.
- Sensible for growing sleepers: The medium feel gives enough give at the shoulder and hip for lighter bodies, so it suits children and teens as well as adults.
- Hypoallergenic for children's rooms: The recycled Eco Comfort Fibre fillings are hypoallergenic and vegan-friendly, a reassuring detail when you're buying for a child.
- Cheap, easy bedding: Single sheets and duvets are the most widely stocked of any size, which keeps running costs down for guest rooms and kids' beds alike.
- Two beds still leave a walkway: For siblings sharing or a guest room set up with a pair of beds, two UK singles fit where one larger mattress would crowd the room.
This size suits you if...
You're buying for a child's or teenager's room where the bed has to share space with storage and a desk, you sleep alone in a compact bedroom or first flat, or you're furnishing a spare room that doubles as an office and needs a guest bed that doesn't dominate the floor.
Consider another size if...
You're an adult who likes room to spread out, or you're likely to share the bed. The UK double is 45cm wider and the same length; we'd recommend it if your room allows at least 2.6m x 2.8m.

What are the dimensions of the Silentnight Mirapocket 1000 UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so any single frame, single fitted sheets and a standard single duvet will fit without any guesswork.
Will the Mirapocket 1000 UK single work on a bunk or mid sleeper frame?
Usually, yes. It's 90 x 190cm, the standard size for bunks, cabin beds and mid sleepers. The one thing to check is depth: at 24cm it's on the deeper side for a raised frame, so measure against the guard rail height before you buy.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves room to get in and out comfortably and open drawers or wardrobe doors, even in a child's room where the bed competes with toy storage and a desk.
Is the Mirapocket 1000 UK single a good choice for a child or teenager?
It's a reasonable fit. The medium feel works for lighter, growing bodies, and the fibre fillings are hypoallergenic, which matters in children's rooms. One small niggle across the range is the lack of handles, slightly awkward if you rotate the mattress regularly.
Should I get the UK single or the UK small double?
The UK single is 30cm narrower than the UK small double, and both are the same length. For a child, teen or occasional guest, the UK single saves useful floor space. If an adult will sleep on it every night and the room allows at least 2.4m x 2.8m, the UK small double is the more comfortable long-term choice.
