Layer Details
Reflex Foam
A 2cm layer of high-density Reflex foam sits at the top, adapting to your shape for enhanced support. It's a thin comfort layer, so expect a supportive feel rather than deep cushioning.
Pocket Springs
Beneath the foam are 800 individual pocket springs, each moving independently for pressure relief and personalised support. Because the springs respond separately, you're less likely to feel a partner shifting about.

Key benefits
- Room for two, room for furniture: At 135 x 190cm the UK double leaves floor space for a wardrobe and chest of drawers in a typical bedroom, where a UK king can crowd the room.
- Quieter nights at close quarters: With 67.5cm each for two sharing, you sleep near your partner, so springs that move independently mean fewer jolts when they turn over.
- Bedside tables on both sides: In a room of 3m x 3m, the comfortable norm we suggest, you can usually fit a bedside table on each side and still walk round.
- Sensible when money is tight: If you're kitting out a whole flat at once, this is a pocket spring double that leaves more of your budget for everything else.
- Ready for visiting couples: The UK double is 15cm wider than the UK small double, so friends or family staying over in the spare room have a proper shared bed.
- Easy to picture in your room: In imperial terms the UK double is 4ft 6in x 6ft 3in, handy if your room plans or old bed frame are measured in feet.
This size suits you if...
You share a bed with a partner and your bedroom needs to hold a wardrobe and drawers too, or you're furnishing a spare room for visiting couples and want a supportive, budget-conscious double that fits.
Consider another size if...
You're over six foot, or you and your partner both sprawl and want more than 67.5cm each. We'd recommend the UK king instead, which is 10cm longer; allow at least 2.7m x 2.9m.

FAQ's
How much space does each person get on a SleepSoul Comfort 800 double?
The UK double gives 67.5cm each for two people sharing. That's cosy rather than roomy, and because across owner reviews some people mention feeling springs near the edges, whoever sleeps on the outside may notice it more on a double than on a wider bed.
Will the SleepSoul Comfort 800 UK double fit in my bedroom?
We suggest a room of at least 2.6m x 2.8m for a UK double, with around 3m x 3m giving you comfortable space for bedside tables and a clear walkway. If your room is smaller than our suggested minimum, measure carefully before ordering.
SleepSoul Comfort 800 double or king for a couple?
The UK king is 15cm wider and 10cm longer, giving 75cm each against 67.5cm on the UK double. If your bedroom allows at least 2.7m x 2.9m and you like elbow room, the UK king is kinder; if space is tight, the UK double is the better fit.
What are the SleepSoul Comfort 800 UK double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm in metric. It's the same length as the UK single and UK small double, so only the width changes if you're swapping between those sizes.
Is the SleepSoul Comfort 800 double good for a guest room?
For visiting couples, yes: the UK double is 15cm wider than the UK small double, so two guests aren't squeezed. The supportive, medium firm feel suits most positions, although lightweight side sleepers may find it slightly firm. If the room is under 2.6m x 2.8m, the UK small double needs at least 2.4m x 2.8m.
