Layer Details
- MemorySense Memory Foam. A memory foam comfort layer that moulds to your body, which means pressure builds more slowly at your hips and shoulders as you settle. It's designed to soothe pressure points and ease aches and pains.
- PostureTech Core Support Springs. A spring system using unique shapes and varied tensions, which means firmer support where your body is heavier and gentler give elsewhere. The result is full-body support with pressure relief rather than a uniformly hard base.
Layer details from mattressonline.co.uk product page, September 2026.
- 90cm of width each: Two people get 90cm each, which means a partner who turns over frequently is far enough away to stop mattering.
- Space that absorbs company: When a child pads in at 3am or the dog settles across the foot, 180cm of width means everyone still gets a workable share.
- Firm support across the full width: The PostureTech springs vary their tension under heavier and lighter areas, so both sleepers get support matched to their own body rather than a compromise.
- Memory foam softens the firm feel: The MemorySense layer moulds slowly under hips and shoulders, easing pressure points without giving up the firm base underneath.
- Fills out a large master: In a period property or generous new build master, a UK super king sits in proportion where a UK king can look a little lost.
This size suits you if...
You share the bed every night and want the most sleeping space a standard UK size offers, your partner is genuinely restless and distance is the fix, or children and pets regularly end up in with you and your current bed can't absorb them. It also suits you if your bedroom comfortably clears the 3m x 2.9m we suggest as a minimum.
Consider another size if...
Your bedroom falls short of the 3m x 2.9m minimum we suggest, or the bed would crowd wardrobes and door swing. We'd recommend the UK king instead: it's 30cm narrower, the same length, and we suggest at least 2.7m x 2.9m for it.

How much space does each person get on the Sealy Eaglesfield super king?
Two people sharing get 90cm each across the 180cm width. In practice that means you can both stretch out, turn over and settle without touching, and the MemorySense foam moulds to each of you individually rather than pulling you towards the middle. It's the width that makes a restless partner easy to ignore.
Will the Sealy Eaglesfield super king fit in my bedroom?
The mattress measures 180 x 200cm, and we suggest a room of at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once you add bedside tables and walking space. That guidance is ours, not Sealy's. Measure your door swing and any landing turns before you commit, because this is a large item to move.
Should I get this Sealy mattress in a UK king or a UK super king?
The UK super king is 30cm wider than the UK king, and the two are the same length. If a restless partner, children or pets are part of your nights, that extra 30cm is where the value sits. If your room is closer to the 2.7m x 2.9m we suggest for the UK king, size down.
Is the super king a good choice if my partner tosses and turns?
Yes, and it's arguably the main reason to buy one. With 90cm each, most movement simply happens too far away to wake you. The memory foam layer helps too, since it responds slowly where each of you lies, but at this size it's the sheer distance doing most of the work.
Does the Sealy Eaglesfield super king work for families sharing with children or pets?
It's well suited to it. At 180cm wide there's usually still room for two adults to sleep properly when a child climbs in, and the firm spring support holds up across the whole surface rather than sagging where extra weight lands. A UK double or UK king gets cramped much faster in the same situation.
