Key benefits
- Leaves room for everything else: At 90 x 190cm, the UK single fits beside a wardrobe and desk, which means a child's bedroom keeps floor space for play and storage.
- Springs under a growing sleeper: As a hybrid, it combines springs with comfort layers, which means a teenager who is filling out still gets a supported, responsive surface rather than sinking into soft foam.
- A steady feel for sharing rooms: Two UK singles side by side with a walkway between them works well for siblings, and the medium firm feel makes getting in and out slightly easier.
- Practical for the spare room: A UK single under a window or against the wall of a study keeps the room usable as an office for most of the year.
- Suits loft conversions: The narrow footprint lets the bed sit tucked under a sloping ceiling, where a wider mattress would push into the space you need to stand in.
This size suits you if...
You're buying for a child or teenager who sleeps alone and needs the rest of the room for a desk and storage, or you're kitting out a spare room or loft conversion where one sleeper and a small footprint matter more than width.
Consider another size if...
You're an adult who sprawls or shares the bed occasionally. We'd recommend the UK small double instead, which is 30cm wider; allow at least 2.4m x 2.8m for it.

FAQ's
Will the Relyon Ultra Cool Gel 2400 UK single fit a bunk bed or mid sleeper?
The width and length match a standard UK single frame. Depth is the unknown: Relyon doesn't publish a depth for this mattress, and raised frames set a maximum so the guard rail stays high enough. Check your frame's mattress depth limit and the brand's own guidance before ordering for a bunk, cabin or mid sleeper.
What room size do I need for a UK single mattress like this one?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open a wardrobe, which is usually what gets squeezed first in a child's bedroom or a box room.
Is a medium firm UK single a good choice for a teenager?
For most teenagers who sleep on their back or move around at night, yes. Medium firm means less sinking in and easier position changes. A lighter teenager who sleeps mostly on their side may find it a little firm at the shoulder, so think about how they actually lie before choosing.
Should one adult choose a UK single or a UK small double?
A UK single at 90cm wide suits a still, solo adult in a tight room. If you spread out, the UK small double is 30cm wider at the same length, though it needs more floor: we suggest at least 2.4m x 2.8m against 2.1m x 2.8m for the UK single.
Is the Relyon Ultra Cool Gel 2400 good for a guest room with two single beds?
It can be. Two UK singles let a room host friends or siblings who would rather not share, and each can be pushed against a wall when the room is back to being a study. Compare the retailers listed on this page, as prices shown here update when retailers change them.
