Memory foam
A cool, breathable open-cell memory foam sits at the top of the mattress. The open-cell structure lets air move through more freely, which means the contouring comfort of memory foam with less trapped heat.
Spring system
Beneath the foam is an advanced dual-layer spring system with 4000 contouring pocket springs. Each spring moves independently, so support adapts to your shape and movement transfers less across the bed.

Key benefits
- Leaves floor space free: At 3ft x 6ft 3in, the UK single leaves room for a desk, wardrobe and toy storage in a small child's bedroom.
- Two can fit side by side: The narrow footprint means siblings sharing a room, or a guest room set up as twins, can have two beds with a walkway between.
- Firm support for growing backs: The 7.5/10 med-firm tension gives a steady, supportive surface, which suits teenagers who sleep on their back or front.
- Cooler foam for a small room: Open-cell memory foam lets air move more freely, which helps in a compact bedroom or loft conversion that can get warm at night.
- Fits under a sloping ceiling: A 90cm width can sit under the low side of a loft conversion where a wider bed would push into the slope.
This size suits you if...
You're buying for a child or teenager who needs firm, even support, your spare room also works as an office and needs space for a desk, or you sleep alone in a compact room and want a hybrid feel without giving up floor space.
Consider another size if...
You share the bed with a partner, or want room to spread out. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Will the Rem-Fit 600 Lux Black Edition UK single fit a bunk bed or mid sleeper?
The mattress is 25cm deep, which is deeper than many raised frames are designed for. Bunks, cabin beds and mid sleepers usually state a maximum mattress depth so the guard rail stays high enough to be safe. Check the frame maker's guidance before buying, and if it allows less than 25cm, choose a slimmer mattress for that bed.
What size bedroom do I need for a Rem-Fit 600 Lux UK single?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves you room to walk around the bed and open drawers or a wardrobe. It is the most forgiving size in the range for box rooms, student rooms and spare rooms with a desk.
Is a UK single Rem-Fit 600 Lux big enough for an adult?
For one adult of average height, a UK single at 90 x 190cm works well. If you are tall, the UK king is 10cm longer, but it is also 60cm wider and needs at least 2.7m x 2.9m, so it only makes sense if your room can take it.
Is the Rem-Fit 600 Lux single too firm for a child?
At 7.5/10 it sits on the firmer side of medium. That suits many children who sleep on their back or front. A light child who sleeps curled on their side may find it a little unyielding at the hip and shoulder, so think about how they sleep before choosing it.
Should I get the Rem-Fit 600 Lux in a UK single or UK small double?
The UK single is 30cm narrower than the UK small double, and both are the same length. If you sleep alone and like room to spread out, the UK small double gives you that extra width, although we suggest at least 2.4m x 2.8m for it. In a tighter room, the UK single is the better fit.
