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
- 75cm each for two people sharing: The UK king is 15cm wider than the UK double, which means a couple gets space to settle without meeting in the middle.
- Less disturbance across a wider bed: The 1,000 pocket springs move independently, and at 150cm wide there's more distance between you, so an early alarm on one side travels less.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, a genuine relief if either of you is approaching six foot.
- Firm support that shares well: A firm mattress resists dipping toward the heavier partner, so each of you keeps your own level surface across the full width.
- Geltex comfort across a bigger surface: The gel-infused layer softens the firm base and lets air move through it, helpful when two bodies are warming one bed.
This size suits you if...
You share the bed every night and a double has started to feel like a compromise, especially if one of you gets up hours before the other. It also fits if either partner is tall enough to appreciate the 10cm of extra length over a UK double, or if a dog has quietly claimed part of the mattress and you'd like your share back.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a UK king, or you sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Sealy Enhance Chrome worth getting in a UK king?
For couples, usually yes. Firm mattresses keep you sleeping on the surface rather than nestled into a dip, so width is felt more keenly than on a softer bed. The UK king's 75cm each for two people sharing gives this firm feel room to work, and the pocket springs limit how much movement crosses the gap.
Will a UK king Sealy Enhance Chrome fit my bedroom?
We suggest allowing at least 2.7m x 2.9m of floor space, and that's our guidance rather than Sealy's. Measure with wardrobes and drawers in mind: a new build master can look generous empty, then feel tight once furniture is in. If the walkways won't work, the UK double needs at least 2.6m x 2.8m.
Is a king size Sealy Enhance Chrome long enough for someone over six foot?
It's a better bet than the smaller sizes. The UK king is 200cm long, which is 10cm more than the UK double, so a sleeper around the six foot mark gets clearance for their feet. If you want more width as well, the UK super king is 30cm wider and the same length.
Does the king size help with partner disturbance on this mattress?
It helps in two ways. The 1,000 pocket springs are individually pocketed, so movement stays localised rather than rippling across the bed, and the 150cm width adds physical distance between you. If one of you leaves for work hours before the other, that combination makes the early exit easier to sleep through.
Should I get the Sealy Enhance Chrome in a king or super king?
The UK king suits most couples: 75cm each for two people sharing, without demanding a huge room. The UK super king is 30cm wider, useful if a child or dog routinely joins you, but we suggest at least 3m x 2.9m of floor space for it. The two are the same length, so height isn't a deciding factor.
