Layer Details
Knitted cover
A soft knitted sleeping surface that adds a touch of cosiness and warmth. Knitted covers are also breathable, so air can pass through rather than building up around you.
Geltex
A breathable foam layer with an open-cell structure, which means heat escapes rather than being held against your body. It's designed for a cooler night's sleep than conventional foams.
Pocket springs
Individual springs encased in cloth pockets that adapt to your movement independently. This gives each part of your body its own level of support and helps limit motion transfer between partners.

Key benefits
- A shared size that fits most rooms: At 135 x 190cm (4ft 6in x 6ft 3in), the UK double sits comfortably in bedrooms where a UK king would dominate.
- Motion isolation matters more at this width: With 67.5cm each for two people sharing, you sleep close, so the pocket springs' independent movement helps when one of you turns over.
- Geltex keeps two sleepers cooler: Two bodies raise the temperature under the duvet, and the open-cell Geltex layer lets that heat escape rather than trapping it.
- Room left for the rest of your furniture: In a first flat or second bedroom, this footprint usually leaves space for a wardrobe, drawers and bedside tables on both sides.
- Easy to dress: Standard double sheets and a 200 x 200cm duvet are sold everywhere, so keeping a spare set is cheap and simple.
This size suits you if...
You share the bed every night and your room sits around the 2.6m x 2.8m minimum we suggest, or you sleep alone and want space to stretch out, perhaps with a dog or cat claiming a corner. It also makes a practical guest bed: visiting couples fit, the medium firm feel suits most people, and the room still works as usable space the rest of the year.
Consider another size if...
You and your partner both like room to move, and your bedroom can take a bigger bed. The UK king is 15cm wider and 10cm longer; we suggest at least 2.7m x 2.9m for it, so measure first.

FAQ's
Is the Sealy Hampton Geltex Enhance in a double big enough for two adults?
It works, with a caveat. At 135cm wide you get 67.5cm each for two people sharing, which is cosier than a UK king. The 1000 pocket springs soften the compromise because they limit the ripple when a partner moves. If either of you is broad shouldered or a restless sleeper, consider the UK king.
What room size do I need for the Sealy Hampton in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows you to walk round the bed and open drawers without shuffling sideways. If you want bedside tables on both sides, measure with those included, since they are usually what tips a tight room into a cramped one.
Will the UK double fit up the stairs in an older house?
Usually, yes. As a hybrid with pocket springs it arrives as a full-size mattress rather than a slim roll, so measure the tightest turn on your stairs or landing against the 135 x 190cm footprint before ordering, particularly in older terraces or new builds with narrow landings.
Should a couple choose this mattress in a double or a king?
It comes down to your room. The UK double is 15cm narrower and 10cm shorter than the UK king, and the UK king needs at least 2.7m x 2.9m by our guidance. If your bedroom clears that comfortably, the extra width is usually the better long-term buy for two. If not, the UK double is the sensible choice.
Is the double a good size for a guest room?
Yes, arguably the best. A UK double accommodates visiting couples as well as solo guests, and the medium firm feel is a safe middle ground when you can't predict who'll be sleeping on it. Its 135 x 190cm footprint also leaves most guest rooms usable for storage or a desk.
