Layer Details
- Pillow Top. A plush pillow top acts as a built-in mattress topper, filled with Comfort Foam layers. In practice this gives you extra cushioning and pressure relief the moment you lie down.
- Cool Gel Memory Foam. A generous layer of Cool Gel Memory Foam actively draws heat away from the body for a cooler sleep. It also gently moulds to your body shape, which means personalised pressure relief at your hips and shoulders.
- Pocket Springs. High tensile steel pocket springs sit in individual fabric pockets and move independently. That means the mattress adapts to changes in your weight distribution through the night, and you feel less of your partner's movement.
- Reinforced Edge Springs. An outer ring of firmer pocket springs reinforces the edges. You can sleep or sit right at the side without the mattress sagging away beneath you.
- Knitted Cover. A knitted cover finishes the mattress. It is hypoallergenic and vegan friendly, useful if allergies are a concern.

- Fits compact rooms: At 90cm wide, it leaves floor space for a desk, wardrobe and toy storage in a child's room, and we suggest just 2.1m x 2.8m of floor space.
- Grown-up comfort for a teen: The pillow top and cool gel memory foam give a growing teenager proper pressure relief rather than the basic foam slab many single beds get.
- Full use of a narrow bed: Reinforced edge springs matter more at 90cm wide, letting a sleeper use the whole width without the side sagging away.
- Cooler for warm sleepers: The cool gel layer draws heat away, which means a child or teen who runs hot won't wake up clammy.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and affordable of any size.
- Guest room ready: In a spare room doubling as an office, a UK single gives visitors a comfortable pillow-top bed while keeping the room usable day to day.
This size suits you if...
You're buying for a child's or teenager's room where the bed shares space with a desk and storage, you're a solo adult in a compact room, student flat or first flat where the frame came with the place, or you want a comfortable guest bed in a spare room that also works as an office.
Consider another size if...
You're an adult who finds 90cm restrictive, or you share the bed even occasionally. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest at least 2.4m x 2.8m of floor space for it.

Will the UK single Coolflex Premium Memory Hybrid fit a bunk or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames, but this mattress is 32cm deep, which is taller than many raised frames allow. Check the frame's maximum mattress depth and guard rail height before buying, especially for a top bunk. On a cabin bed, also check the ladder cutout still clears the pillow top.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk around and open drawers. That makes it a comfortable fit in box rooms, loft conversions with a narrow usable footprint, and children's rooms where the bed competes with a desk and wardrobe.
Is the Coolflex Premium Memory Hybrid UK single long enough for a tall teenager?
At 190cm (6ft 3in) long, it suits most teenagers and adults comfortably. If the sleeper is approaching six foot and still growing, bear in mind that all sizes up to the UK double share the same 190cm length, so upgrading width alone won't add legroom. The UK king is 10cm longer as well as 60cm wider.
Can two UK singles work in a shared children's room or guest room?
Yes, and it's often the practical choice. Two 90cm-wide beds plus a walkway between them fit in a reasonably sized shared room, and each sleeper gets their own pocket-sprung mattress. For guests, two UK singles are more flexible than one double: they suit friends, siblings or a couple depending on who visits.
Is a UK single wide enough for an adult?
For one adult sleeping alone, 90cm is workable, and the reinforced edge springs help because you can sleep right to the side without it giving way. If you move around a lot at night or share the bed even occasionally, the UK small double is 30cm wider at the same length and worth the step up.
