Layer Details
Knitted Cover
A soft knitted cover that is breathable, which means heat can escape rather than gathering at the surface. It helps keep you at an even temperature all night.
Cool Gel Memory Foam
A thick layer of cool gel-infused memory foam that gives you the contouring and pressure relief of standard memory foam. The gel infusion helps maintain optimum body temperature, so you sink in without overheating.
Pocket Springs
The foundation is over 800 individually wrapped pocket springs, each moving independently. That means bespoke, targeted support for each part of your body rather than a one-size response.

Key benefits
- Fits compact rooms: At 90cm wide it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or a walkway between two beds where siblings share.
- Cooling that matters for teens: The gel-infused memory foam is designed to hold an even body temperature, useful for teenagers who sleep warm in small, poorly ventilated rooms.
- Full-length sleeping space: The UK single is the same 190cm length as the UK small double and UK double, so a taller teen or adult guest isn't shortchanged.
- Support that suits growing sleepers: Over 800 pocket springs respond to shoulders and hips individually, so a lighter body still gets targeted support rather than lying on top of a firm slab.
- Guest room ready: In a spare room doubling as an office, a UK single gives visitors a proper hybrid mattress while keeping most of the floor free for a desk.
This size suits you if...
You're buying for a child or teenager who has outgrown a smaller bed, you sleep alone in a compact room or a first flat where the frame came with the tenancy, or you want a guest bed that doesn't dominate a spare room. The 2.1m x 2.8m floor space we suggest fits almost any UK bedroom, including a loft conversion with a narrow usable footprint.
Consider another size if...
You're an adult who moves around at night, or two people will ever share it. The UK small double is 30cm wider at the same length; we'd recommend it instead, allowing at least 2.4m x 2.8m of floor space.

FAQ's
Is the Coolflex Hybrid ICE UK single good for a child's bedroom?
Yes, with one caveat. The 90 x 190cm footprint leaves space for a wardrobe, desk and storage in a typical child's room, and the hypoallergenic build is reassuring for young sleepers. The medium firm feel may seem slightly solid to a very light child, though the pocket springs do adjust to smaller bodies better than a flat foam block would.
Will the Coolflex Hybrid ICE single fit a bunk bed or mid sleeper?
The 90 x 190cm size matches standard UK bunk and mid sleeper frames, but check depth before buying. At 26cm, this mattress is deeper than many raised frames allow, and a tall mattress can bring a child above the safety rail on a top bunk. Measure your frame's maximum mattress depth first.
What room size do I need for a UK single Coolflex Hybrid ICE?
We suggest at least 2.1m x 2.8m of floor space, which gives you room to walk alongside the bed and open drawers or wardrobe doors. That makes the UK single a sensible pick for box rooms, loft conversions where the bed sits under the slope, and spare rooms that also hold a desk.
Is a UK single big enough for an adult on the Coolflex Hybrid ICE?
For a solo adult who sleeps fairly still, yes: at 190cm it's the same length as the UK double, so height is rarely the problem. Width is the constraint. If you spread out or turn a lot, 90cm can feel restrictive, and the UK small double adds 30cm of width without any extra length.
Can I put two Coolflex Hybrid ICE singles in one guest room?
Often, yes, and it's a flexible setup for hosting friends or grandchildren who won't share a bed. Each mattress needs its share of a 2.1m x 2.8m footprint plus a walkway between the two, so measure carefully.
