Key Benefits of the Silentnight Just Sleep Breathe Single Mattress

  • Fits compact rooms: At 90cm wide, this size leaves floor space for a desk, wardrobe or toy storage in a child's or teenager's bedroom.
  • Works where two beds are needed: Siblings sharing a room, or a guest room set up with twin beds, can fit two UK singles with a walkway between them.
  • Arrives rolled: Because the Just Sleep range comes rolled and boxed, getting a single up a loft staircase or into a box room is far easier than manhandling a flat mattress.
  • Cheap, easy bedding: Single sheets and duvets are the most widely stocked and lowest priced of any size, which keeps running costs down.
  • Suits a spare room that's really an office: A UK single takes up the least floor space of any adult size, so the room stays usable as a study between guests.

Who should buy the Silentnight Just Sleep Breathe Single Mattress?

This size suits you if...

You're buying for a child's or teenager's room where the bed shares floor space with a desk and storage, you're kitting out a spare room or study that occasionally hosts a guest, or you're a single adult in a compact bedroom, a loft room or a first flat where a wider mattress simply wouldn't fit.

Consider another size if...

You're an adult couple, or a solo sleeper who spreads out and has the floor space to spare. We'd recommend the Silentnight Just Sleep Breathe in a UK double instead, allowing at least 2.6m x 2.8m of room.

FAQ's

Frequently Asked Questions About the UK Single

How big is the Silentnight Just Sleep Breathe in a UK single?

It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits standard single bed frames and takes standard single bedding, including a 135 x 200cm single duvet. We suggest a room of at least 2.1m x 2.8m to leave sensible walking space around it.

Will the Just Sleep Breathe single fit a bunk bed or mid sleeper?

The width and length match standard UK bunk and mid-sleeper frames. The catch is depth: raised frames often set a maximum mattress height so the guard rail still does its job, and Silentnight doesn't publish a depth for this model. Check the measurement on the retailer listing against your frame's limit before buying.

Is a UK single big enough for an adult?

For one adult in a compact room, yes, 90cm of width is the accepted one-person standard and 190cm of length suits most heights. If you tend to spread out and the room allows, the UK small double is 30cm wider at the same length, and we'd suggest a room of at least 2.4m x 2.8m for it.

How much smaller is the UK single than the UK double?

The UK single is 45cm narrower than the UK double, and the two are the same length. That extra width is why couples should skip straight to the double, for which we suggest a room of at least 2.6m x 2.8m. For one sleeper, the single frees up that 45cm as floor space instead.

Where can I buy the Just Sleep Breathe in a single?

Stock moves around, so the most reliable answer is the live comparison table on this page, which is updated as retailers change their prices and availability. Given that construction details for the Breathe model are thin, it's also sensible to read the retailer's own listing carefully before you order the UK single.
