Key benefits
- Fits a crowded child's room: We suggest at least 2.1m x 2.8m of floor space, so a UK single can sit beside a wardrobe and a desk without making the room feel cramped.
- Two beds in one guest room: At 90cm wide, a pair of UK singles lets a spare room sleep two friends or siblings separately, with a walkway between the beds.
- Cooler for warm teenagers: The CoolEase woven cover pulls heat away from the body, which helps a teenager who runs hot and kicks the duvet off by midnight.
- Support for one sleeper: The 1600 pocket springs sit under a single body, with reflex foam cushioning the shoulders and hips of whoever sleeps on it.
- Easy bedding to find: Standard single sheets fit the UK single, and so does a single duvet (135 x 200cm), so replacements for a child's bed are easy to find.
This size suits you if...
You're furnishing a child's or teenager's bedroom where the bed has to share space with storage and a desk, or you want two separate beds in a guest room. It also suits a solo adult in a small flat or a loft conversion, where a narrow bed is the only one that fits.
Consider another size if...
You share a bed, or you're an adult who sprawls and wants more width to yourself. We'd recommend the UK small double instead: it is 30cm wider and the same length, and we suggest at least 2.4m x 2.8m for it.

FAQ's
What are the dimensions of the Silentnight SleepResponse Reflex 1600 UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That is the standard UK single size, so it should fit any frame sold as a UK single. The mattress is 26cm deep.
Will the Reflex 1600 UK single fit a bunk bed or mid sleeper?
It will fit the frame's footprint, but at 26cm deep it is a fairly thick mattress for a raised bed. Bunks, cabin beds and mid sleepers often set a maximum mattress depth so the guard rail stays high enough. Check the frame maker's guidance before you order.
How much room do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m. That leaves space to walk around the bed and open drawers or a wardrobe door, which matters most in a child's room or a box room used as a study.
UK single or UK small double for an adult sleeping alone?
The UK single is 30cm narrower than the UK small double, and the two are the same length. If you have the floor space, we suggest at least 2.4m x 2.8m for the UK small double, and an adult who moves around a lot will appreciate the extra width.
Is a UK single long enough for a tall teenager?
The UK single is 190cm long, which is 10cm shorter than the UK king. A teenager still growing may find their feet near the edge in a few years. Nothing in the single range is longer, so a very tall sleeper would need to size up to the UK king to gain length.
