Layer Details
- Belgian Damask Viscose Sleep Surface. A silky, breathable cover that helps keep the sleep surface feeling fresh. It's the first thing you'll feel, and it's noticeably softer than the firm rating might suggest.
- Sustainably Sourced Somerset Wool. Wool is naturally breathable and gently cushioning, which means it helps regulate your temperature through the night. It also gives the firm build a touch of resilient comfort at the surface.
- Soft White Fibres. These fibres are made from 100% polyester, chosen for recovery and durability. In practice, that means the comfort layers should hold their shape rather than flattening quickly.
- Cotton. A natural filling that helps regulate body temperature and adds a layer of support. Combined with the wool above it, this keeps the mattress breathable throughout.
- 2500 Pocket Springs. Each spring sits in its own fabric pocket and works independently, which means better pressure relief and less motion transfer than an open coil unit. Additional mini pocket springs provide closer, more responsive support.

- Small footprint: At 3ft x 6ft 3in, the UK single leaves room for a wardrobe and desk, which means a child's bedroom can still hold everything else it needs.
- Cooler for one: The Somerset wool and cotton fillings breathe well, which suits a teenager's room that gets stuffy with the door shut and a computer running.
- Firm support for growing bodies: The pocket springs move independently to follow a changing shape, although a very light younger child may find the firm feel slightly unyielding.
- Two singles for a guest room: Two UK singles side by side let a spare room sleep two friends or siblings separately, each on the same firm, even feel.
- Fits compact and sloped rooms: The narrow 90cm width can slip under a loft conversion's sloping ceiling where a wider bed would leave you with no headroom to sit up.
This size suits you if...
You sleep alone and want firm, breathable support without giving up floor space, or you're furnishing a child's or teenager's room where storage and a desk compete for the walls. It also fits if you're setting up a spare room that works as an office most of the week.
Consider another size if...
You share the bed with a partner most nights. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m for it.

Will the Relyon Wallbridge Ortho 2500 single fit a bunk bed or mid sleeper?
The width and length match standard single frames, but the mattress is 29cm deep, which is taller than many raised frames allow. Check your bunk, cabin or mid sleeper's maximum mattress depth before buying, because a deep mattress reduces the effective height of the safety rail on the top bunk.
How much room do I need for a Relyon Wallbridge Ortho 2500 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves enough clearance to walk around the bed, open a wardrobe door and pull out a desk chair, which matters most in a child's room or a box room.
Is the Relyon Wallbridge Ortho 2500 single suitable for a child?
It can be, particularly for an older child or teenager who wants firm support. Younger, lighter children put less weight on the springs, so they may find the surface a little too firm. The wool and cotton layers do soften the first feel, and they help if your child tends to overheat at night.
Is a UK single big enough for an adult on the Relyon Wallbridge Ortho 2500?
For one adult of average height, yes: the UK single is 90cm wide and 190cm long. If you're tall, the UK king is 10cm longer, although it is also 60cm wider, so we suggest at least 2.7m x 2.9m of floor space for the UK king.
Should I buy the Relyon Wallbridge Ortho 2500 as a single or a double for a spare room?
The UK single is 45cm narrower than the UK double and the same length. Choose the UK single if the spare room also works as an office and you need the floor space. Choose the UK double if couples stay over; we suggest at least 2.6m x 2.8m for it.
