Layer Details
Memory Foam
A 2cm top layer that responds to body temperature, which means it softens where you press into it and spreads your weight evenly for soothing pressure relief. It's a slim layer, so expect a gentle cushion rather than a deep sink-in feel.
Pocket Springs
800 pocket springs run edge to edge and react independently to your movements, giving personalised support with no roll-together. That independence means you're less likely to be disturbed when a partner shifts in the night.

Key benefits
- Space for bedside tables: We suggest a room of at least 2.6m x 2.8m for a UK double, which in most bedrooms leaves space for a bedside table on each side.
- Less disturbance at close quarters: At 67.5cm each for two sharing you sleep fairly close together, so springs that move independently make more difference here than they would on a solo bed.
- Support right to the sides: The pocket springs run edge to edge, which means the side of the UK double still feels supportive when one of you ends up sleeping near it.
- Easy, affordable bedding: Double sheets and a 200 x 200cm double duvet fit it and are sold almost everywhere, which helps if you're furnishing a whole home and the budget is stretched.
- A proper bed for visiting couples: In a guest room, a UK double gives visiting couples a shared bed rather than a squeeze, and the medium firm feel should suit most people for a few nights.
This size suits you if...
You share the bed every night with a partner and your bedroom is at least 2.6m x 2.8m, or you're setting up a guest room where couples will stay and want a shared bed without a large outlay.
Consider another size if...
One of you sleeps restlessly or is tall enough to find 190cm limiting. We'd recommend the UK king instead, which gives 75cm each for two sharing and needs at least 2.7m x 2.9m.

FAQ's
Is the SleepSoul Balance 800 UK double wide enough for two adults?
It gives 67.5cm each for two people sharing, which works for most couples who sleep fairly still. The independently reacting springs help, because you'll feel less of each other's movement. If you want more room, the UK king gives 75cm each, so the UK double gives you 7.5cm less each.
Will a SleepSoul Balance 800 double fit in a small bedroom?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable once you add bedside tables and a wardrobe. If your room is tighter than that, the UK small double would suit you better, and we suggest at least 2.4m x 2.8m for it.
Is the SleepSoul Balance 800 double long enough for tall people?
The UK double is 190cm long, the same length as the UK small double and the UK single, so moving between those sizes changes only the width. If legroom matters to you, the UK double is 10cm shorter than the UK king, and that extra length is the main reason taller couples size up.
What are the SleepSoul Balance 800 UK double dimensions in feet?
The UK double measures 4ft 6in x 6ft 3in, or 135 x 190cm. That's the standard UK double size, so it fits any bed frame sold as a UK double. Check your frame's internal measurements before ordering, as an older or imported frame may differ.
How much wider is the Balance 800 double than the small double?
The UK double is 15cm wider than the UK small double, and both are the same length. That extra width is what makes the UK double practical for two people every night, while the UK small double tends to suit solo sleepers or couples in a smaller room.
