Layer Details
Quilted Cover
The cover and fillings are stitched together into a patterned comfort quilt, which means the top surface feels cushioned and stays in place rather than shifting around. It gives the mattress a soft first touch before you reach the firmer layers below.
Geltex®
Geltex is a gel-infused foam that shapes to your body for pressure relief while remaining breathable, so it shouldn't trap heat the way traditional memory foam can. It sits between you and the springs to soften that firm base.
Pocket Springs
The Chrome has 1,000 individually mounted springs, each sewn into its own fabric pocket so it can move independently of its neighbours. In practice, this means better contouring to your shape and less motion transfer between partners.

Key benefits
- A shared footprint that fits: At 135 x 190cm, the UK double squeezes into most bedrooms with room left for bedside tables on both sides, which a UK king often rules out.
- Pocket springs matter more when sharing: The 1,000 individually pocketed springs move independently, so at 67.5cm each for two people sharing you feel less of your partner's turning.
- Two warm bodies, one breathable layer: Geltex is a gel-infused foam designed to let air move through, useful when two of you are heating the same 135cm of mattress.
- Easy to dress, easy to move: Standard double sheets and a 200 x 200cm duvet are stocked everywhere, and at 26cm deep it takes ordinary fitted sheets without a fight.
- Firm support at couple scale: You get the stability of a firm hybrid across the classic shared size, without paying UK king money for width you may never use.
This size suits you if...
You share the bed every night and your room is a typical UK size, around our suggested minimum of 2.6m x 2.8m or a little over. It also suits a solo sleeper who wants space to spread out, perhaps with a dog or cat claiming a corner, or anyone furnishing a guest room that hosts visiting couples and needs a firm mattress that suits back and front sleepers.
Consider another size if...
You and your partner both like room to sprawl, or one of you is tall. The UK king is 15cm wider and 10cm longer, and we'd recommend it if your room allows at least 2.7m x 2.9m.

FAQ's
How much space does each person get on a UK double Sealy Enhance Chrome?
With two people sharing, you get 67.5cm each. That is enough for most couples, helped here by the 1,000 pocket springs, which reduce how much of your partner's movement crosses to your side. If either of you sleeps starfish-style, the UK king adds 15cm of width and 10cm of length.
What room size do I need for the Sealy Enhance Chrome in a UK double?
We suggest allowing at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That leaves walking space and, in most rooms, enough wall for bedside tables on both sides. Measure with the door swing and wardrobes in mind before you order, especially in older terraces or compact new builds.
Is the UK double Sealy Enhance Chrome a good guest room mattress?
It works well for a guest room that hosts visiting couples, since the UK double is the traditional shared size and fits rooms a UK king would dominate. Bear in mind it is a firm mattress, so back and front sleeping guests will get on with it better than lightweight side sleepers.
What are the dimensions of the Sealy Enhance Chrome UK double in feet?
It measures 4ft 6in x 6ft 3in, which is 135 x 190cm. The length is the same as the UK single and UK small double; if you want extra length as well as width, the UK king is 10cm longer. Standard double bedding fits, including a 200 x 200cm duvet.
Should a couple choose this Sealy in a UK double or a UK king?
It comes down to your room. The UK king is 15cm wider and 10cm longer, and we suggest at least 2.7m x 2.9m of floor space for it. If your bedroom clears that comfortably and you both value space, size up. In a typical UK bedroom, the UK double keeps the room usable.
