Layer Details
Knitted cover
A soft knitted cover with micro-quilting, which keeps the fillings securely in place so the surface stays even. It's finished with Bio-Protect technology and adds a touch of warmth and cosiness.
Soft White Fibres
Soft synthetic fillings sit beneath the cover to create a cosy feel over the springs. They're designed to be durable and resilient, holding their shape over time.
Pocket Springs
1,000 individual Posturepocket springs, each encased in its own cloth pocket, which means they respond to your body independently and reduce movement transferring across the bed. Two firmer outer rows around the edge give edge-to-edge support.

Key benefits
- A footprint that leaves room to live: At 90cm wide, this mattress leaves floor space for a desk, wardrobe and toy storage in even a compact child's bedroom or a loft room under the slope.
- Edge support matters more in a narrow bed: Two firmer outer rows of springs mean you can sleep right up to the side, useful when the whole bed is only 3ft wide.
- Grows with a child: The medium firm feel keeps a growing spine fairly level, so it can carry a child through the teenage years rather than needing replacing early.
- Movement stays where it is: Each of the 1,000 Posturepocket springs responds independently, which means a restless sleeper in a shared kids' room disturbs the bed less than a traditional open coil would.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and least expensive bedding of any UK size.
This size suits you if...
You're buying for a child or teenager and want a supportive, traditional build rather than foam, you need a dependable bed for a spare room that doubles as an office, or you're a single adult in a first flat where the frame came with the room and the mattress didn't. It also suits guest rooms set up with two singles instead of one double.
Consider another size if...
You share the bed, or you're a lightweight side sleeper who needs more give at the shoulder and hip. This mattress is only made in a UK single, so couples and softer-feel sleepers will need a different model.

FAQ's
What room size do I need for the Relyon Comfort Pure 1000 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk around the bed and open drawers or a wardrobe. That makes it workable in box rooms, loft conversions with a narrow usable footprint, and children's bedrooms where the bed competes with storage.
Will the Relyon Comfort Pure 1000 single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames. The one thing to check is depth: at 26cm this is deeper than many mattresses sold for raised frames, and top bunks usually need the mattress to sit below the safety rail. Measure your frame's maximum depth before buying.
Is the Relyon Comfort Pure 1000 UK single suitable for a child?
Yes, with a caveat on feel. The medium firm support keeps a growing spine fairly level, and the pocket springs settle movement quickly, helpful when siblings share a room. Very light children may find it slightly solid at first, though most adapt, and it should last well into the teenage years.
Can two singles work instead of a double in a guest room?
They can, and this mattress suits that setup. Each UK single is 90cm wide, so two side by side give guests more personal space than a UK double, and they work for friends or family who'd rather not share. You'll need roughly two bed widths plus a walkway between them.
Is a UK single big enough for an adult on this mattress?
For one average-sized adult, yes. At 90 x 190cm it's the standard UK one-person size, and the firmer outer spring rows let you use the full width without feeling you might roll off. Taller sleepers should note the 190cm length; anyone over about 6ft may prefer a longer size, which this model doesn't offer.
