AlignSupport Coil system
A patented, twice-tempered coil with a UniCased edge. It gives deep-down support and a supportive edge, so the mattress stays stable when you sit or sleep near the side.
MemorySense ComfortCore
A comfort core positioned to support the hips and lower back for pressure relief. You get a little cushioning where your body presses down most.
Extra firm foam
A double layer of extra firm foam sits alongside the ComfortCore. It keeps the surface flat and firm, with very little sink.

Key benefits
- Room for bedside tables: At 135cm wide, the UK double usually leaves space for a table on each side, so neither of you has to climb over the other for a glass of water.
- Support right to the side: With 67.5cm each, couples often sleep near the side, and the UniCased edge keeps that outer strip stable rather than sloping away beneath you.
- Shared firmness, no compromise: The whole surface is extra firm, which suits a couple who both prefer a flat bed but means a partner who likes some give will feel little of it.
- Hip support for both sleepers: The MemorySense ComfortCore sits under the hips and lower back, so each person gets a little cushioning where the body presses down most.
- Easy to dress: Standard double sheets fit, and a 200 x 200cm double duvet gives two people enough to share without tugging it back and forth.
This size suits you if...
You share the bed with a partner in a bedroom of ordinary size, you both want a flat, very firm surface, and you'd rather keep floor space for a wardrobe and drawers than fill the room with mattress.
Consider another size if...
You and your partner find 67.5cm each too tight, or one of you spreads out at night. We'd recommend the UK king instead, provided your room allows at least 2.7m x 2.9m.

FAQ's
Is the Sealy Elevate Hagen UK double big enough for two people?
For most couples, yes. The UK double gives 67.5cm each, which is 7.5cm less per person than the UK king. Because the surface is extra firm, you won't sink towards each other much, and the UniCased edge keeps the outer strip usable. Larger sleepers, or anyone who sprawls, may find the space a little tight.
What size bedroom do I need for a Sealy Elevate Hagen double?
We suggest at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable. That usually leaves room for bedside tables on both sides and a clear path round the foot of the bed. In a smaller second bedroom, measure the wall where the headboard will sit before deciding.
What are the dimensions of the Sealy Elevate Hagen UK double in feet?
The UK double measures 135 x 190cm, which is 4ft 6in x 6ft 3in. It is 28cm deep. If you are replacing an older double, measure your current bed frame against those figures, as some older frames run slightly smaller.
Should I choose the UK double or UK king Sealy Elevate Hagen for a couple?
Choose the UK double if room space matters more than personal width. The UK king is 15cm wider and 10cm longer, giving 75cm each, but we suggest at least 2.7m x 2.9m for it. If your bedroom sits close to 2.6m x 2.8m, the UK double will leave the room feeling far less crowded.
What bedding fits a Sealy Elevate Hagen UK double mattress?
Standard UK double sheets and a 200 x 200cm double duvet fit. The mattress is 28cm deep, so check the pocket depth on fitted sheets before buying. Double bedding is easy to find at every level, which helps if you're furnishing a whole home at once and want to spend more of your budget on the mattress itself.
