Layer Details
- 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.

- Room to stretch out alone: The UK small double is 30cm wider than the UK single, which means you can sleep diagonally or starfish without an arm dropping off the edge.
- Fits rooms a double would crowd: Being 15cm narrower than the UK double, it leaves slightly more floor free, so a wardrobe door or a bedside table is less likely to be squeezed out.
- Calmer for occasional sharing: The 4000 independently moving pocket springs limit how much movement travels across the mattress, useful when a visiting couple share a narrower surface for a night or two.
- Breathable foam for smaller rooms: The open-cell memory foam is designed to let air move through it, which helps if your small double sits in a snug loft conversion that holds warmth.
- Easy to dress: At 4ft x 6ft 3in, it takes standard UK small double fitted sheets, so bedding is simple to find on the high street.
This size suits you if...
You sleep alone but want more width than a single gives, your bedroom only has space for a narrower double, or you're kitting out a guest room where couples stay now and then rather than every night.
Consider another size if...
You share the bed with a partner every night. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; we suggest at least 2.6m x 2.8m for the UK double.

Is the Rem-Fit 600 Lux small double big enough for one adult?
For most solo sleepers, yes. The UK small double measures 120 x 190cm, and that is 30cm wider than the UK single, so you can turn over and spread out comfortably. The firmer 7.5/10 feel keeps the surface supportive right across the width, which suits back and front sleepers who like to move around.
What room size do I need for a Rem-Fit 600 Lux UK small double?
We suggest allowing at least 2.4m x 2.8m for a UK small double. That leaves space to walk around the bed and open drawers or a wardrobe. If your room is tighter than that, a UK single needs less floor, and we suggest at least 2.1m x 2.8m for it.
Can a couple share the Rem-Fit 600 Lux small double for guest stays?
For the odd weekend, it works well. The pocket springs move independently, so one person turning over disturbs the other less. It is snug for two every night, though. If a couple will use the room regularly, the UK double gives 67.5cm each for two sharing and needs at least 2.6m x 2.8m.
Is a UK small double Rem-Fit 600 Lux a good upgrade for a teenager?
It suits a teenager who has outgrown a single but whose room can't spare much more floor. The UK small double is the same length as the UK single and 30cm wider. Lighter teens who sleep on their side may find the 7.5/10 tension a little firm at the shoulder and hip, though.
How long is the Rem-Fit 600 Lux small double for tall sleepers?
The UK small double is 4ft x 6ft 3in, or 120 x 190cm, which is the same length as the UK double. If your feet already reach the end of a standard bed, the UK king is 10cm longer, although it needs a room of at least 2.7m x 2.9m.
