Layer Details
- Cover. A simple polyester cover. The fabric is OEKO-TEX® certified, so it is free from harmful chemicals.
- Advance e-Fibre™. An extra-soft layer of Advance e-Fibre™, which means a luxurious, cushioned feel as soon as you lie down.
- Memory e-Fibre™. This layer adapts to the shape and weight of your body, giving memory foam-style pressure relief. It is 100% foam-free with a breathable cell structure, which means better air flow than traditional memory foam.
- Spring core. A deep sprung open coil core, with 325 springs in the king size, for evenly distributed support. Spring counts for other sizes are not stated.

- Fits compact rooms: At 90cm wide it leaves space for a desk, wardrobe and toy storage in a child's bedroom, or a walkway between two beds where siblings share.
- Works with raised frames: At 22cm deep it suits many bunk, cabin and mid-sleeper frames, though you should check it sits below the guard rail height on the top bunk.
- A cooler feel for children: Memory e-Fibre™ contours like memory foam but stays foam-free and breathable, useful for children and teens who run warm at night.
- Medium feel for guests: The medium tension is a sensible middle ground for a spare room, where you can't predict whether guests prefer soft or firm.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
This size suits you if...
You're buying for a child or teenager and want pressure relief without the heat of traditional memory foam, you need a mattress for a bunk, cabin or mid-sleeper frame, or you're kitting out a spare room or study that doubles as guest space and the floor plan only allows a 3ft bed.
Consider another size if...
You're an adult sleeping alone and would like more room to stretch out. The UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

What are the dimensions of the Jay-Be Ryze in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard one-person size in the UK, so standard single fitted sheets and a single duvet (135 x 200cm) fit without any hunting for unusual bedding.
Will the Jay-Be Ryze UK single work on a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames. The Ryze is 22cm deep, which suits many raised frames, but for a top bunk check your frame's maximum mattress depth first so the guard rail still sits safely above the sleeping surface.
How much floor space does a UK single Jay-Be Ryze need?
We suggest allowing at least 2.1m x 2.8m. That gives you room to walk alongside the bed and open drawers or a wardrobe. In a child's room it usually leaves space for a desk as well, and in a loft conversion the narrow footprint helps under a sloping ceiling.
Is the Jay-Be Ryze UK single a good mattress for a child or teenager?
It's a reasonable fit. The medium feel suits most growing sleepers, the Memory e-Fibre™ cushions hips and shoulders without foam's heat build-up, and the cover fabric is OEKO-TEX® certified, so it's free from harmful chemicals. Children who want a distinctly firm surface may find it a little soft.
Should I choose the Jay-Be Ryze in a UK single or a UK small double?
For a child, a bunk frame or a tight guest room, the UK single is the practical choice. For an adult sleeping alone most nights, the UK small double is 30cm wider at the same length and gives noticeably more room to turn; allow at least 2.4m x 2.8m of floor space for it.
