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
- Room to sleep apart, together: At 75cm each for two people sharing, you can both stretch out without negotiating the middle of the bed.
- Less disturbance when one of you moves: Individually pocketed springs absorb movement locally, so an early alarm on one side is less likely to wake the other.
- Extra length for taller sleepers: At 200cm long, the UK king adds 10cm over the UK double, welcome if either of you is approaching six foot.
- Cooler when two of you share: Two bodies mean more heat, and the open-cell Geltex layer lets air move through rather than trapping warmth between you.
- A step up without super king demands: The UK king is 15cm wider than the UK double, a difference you feel nightly, without the floor space a UK super king needs.
This size suits you if...
You share the bed every night and the middle of your double has become contested ground, one of you gets up hours before the other and you'd rather they slipped out unnoticed, or one partner is tall enough that their feet reach the end of a standard-length mattress and the 200cm length would be a genuine relief.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m, or you sleep alone. We'd recommend the UK double instead, which needs a room of at least 2.6m x 2.8m.

FAQ's
Is a UK king Sealy Hampton Geltex big enough for a couple?
Comfortably, for most. The UK king gives 75cm each for two people sharing, and the 1000 pocket springs respond to each sleeper independently, so you feel less of your partner's movement. If a dog routinely claims part of the bed too, you may find the UK super king, at 30cm wider, a better long-term buy.
Will the king size reduce partner disturbance on this mattress?
It should help on two fronts. The pocket springs move independently, so a partner turning over or getting up early creates less ripple across the surface. The width does the rest: with 75cm each for two people sharing, you're less likely to be touching in the first place, which is where most disturbance starts.
Is the Sealy Hampton Geltex UK king long enough for tall sleepers?
At 200cm, the UK king is 10cm longer than the UK double, and for anyone around six foot that extra length is often the real reason to size up. The UK super king offers no advantage here; it is the same length as the UK king, only 30cm wider.
What room size do I need for this mattress in a UK king?
We suggest at least 2.7m x 2.9m. That allows walking space on both sides and room for doors and drawers to open. New build master bedrooms can be tighter than they first appear once wardrobes go in, so measure the usable floor rather than the full room.
Where can I buy the Sealy Hampton Geltex Enhance in a UK king?
Compare the retailers listed on this page; the prices shown are updated as retailers change them, so what you see reflects current stock rather than a snapshot. The UK king is 5ft x 6ft 6in in imperial terms, which is handy to know when checking bed frame listings that use feet.
