Key benefits
- More room each than a UK double: You each get 75cm of width, which is 7.5cm more than a UK double, so an early riser can slip out with less chance of nudging the other awake.
- Length for taller partners: At 200cm long, or 6ft 6in, the UK king is 10cm longer than a UK double, so a partner over six foot is less likely to have their feet near the end.
- Edges you can use: UniCased XT edge support helps the sides hold their shape, which matters on a UK king where each of you sleeps a little closer to your own edge.
- A cooler cover for two: The SmarTex Plus cover with Tencel fibres is designed to regulate temperature, useful when two bodies share one surface through a warm night.
- Medium feel for a shared bed: The medium comfort grade gives contouring without a sunk-in feel, a sensible middle ground when two people with different tastes share one mattress.
This size suits you if...
You share the bed every night and keep waking when your partner turns over or gets up hours before you, or one of you is around six foot and has outgrown the length of a UK double. It also suits couples whose dog has claimed a corner of the bed as its own.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's
Is the Sealy Elevate Ultra Antuco UK king big enough for two people?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more each than a UK double. That is enough for many partners to stop feeling crowded, although if one of you sprawls or you share with a dog, the UK super king gives 90cm each.
What size bedroom do I need for a UK king mattress?
We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable once you add bedside tables on both sides. New build master bedrooms can feel tighter than the floor plan suggests after built-in wardrobes go in, so measure from the wardrobe doors rather than the wall.
Is a UK king long enough if I'm over 6ft?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than a UK double. If one partner is around or over six foot, that extra length can matter more than the width. The UK super king is the same length, so sizing up beyond the UK king adds width only.
Should I get the Sealy Antuco in a UK king or UK super king?
Choose the UK super king if you want maximum space: it is 30cm wider and gives 90cm each, but we suggest at least 3m x 2.9m of room. The UK king gives 15cm less each and suits rooms from 2.7m x 2.9m, so measure the bedroom first, then compare the retailers listed on this page.
What bedding fits a Sealy Elevate Ultra Antuco UK king?
Standard UK king sheets fit, and a 230 x 220cm king duvet covers it well. The mattress is 34cm deep, so check that any fitted sheet has a pocket deep enough for that depth before you buy, as shallow sheets can pull off the corners.
