Key benefits
- 90cm each for two sharing: Each of you gets 90cm of width, so a partner who turns often, or a child who wanders in at 3am, becomes far easier to sleep through.
- Distance offsets the open coil feel: Open coil springs move more as a unit than pocket springs, and at this width you're simply further from the disturbance, which softens that trade-off.
- Edge support you can actually use: Sealy's Unicased edge firms up the perimeter, which means the outer inches of a 180cm-wide bed stay usable rather than feeling like a slope.
- Room for the whole household: Children or a large dog joining you as routine is the classic reason to size up this far, and the medium feel suits a mix of sleeping positions.
- Cooling has more to do: The temperature regulating layer covers a bigger surface here, useful when three bodies rather than two are generating the heat.
This size suits you if...
You share the bed every night and want the maximum space a standard UK size offers, your partner is genuinely restless and you'd rather have distance than hope a comfort layer absorbs the movement, or children and pets treat your bed as theirs and a UK king has started to feel crowded. Your bedroom should be at least 3m x 2.9m, and larger will feel better.
Consider another size if...
Your room falls short of the 3m x 2.9m we suggest, or you sleep alone and the width would go unused. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs a room of at least 2.7m x 2.9m.

FAQ's
Is the Sealy Perfection Plush super king good for restless couples?
Yes, with a caveat. The open coil system moves more as a unit than pocket springs, so some motion does travel. At 180cm wide, though, you each get 90cm and sleep well apart, which does more to protect your night than any spring type. The firm Unicased edges also let you spread right to the sides.
What room size do I need for the super king Sealy Perfection Plush?
We suggest at least 3m x 2.9m for a UK super king, and that's our guidance rather than Sealy's. In a period property master or a good-sized new build main bedroom it looks proportionate; in anything smaller you'll be squeezing past the footboard. Measure door swing and any landing turns before you commit.
Should I choose the UK king or UK super king in this mattress?
The UK super king is 30cm wider than the UK king and the same length. If children or pets regularly share, or one of you is a restless sleeper, that extra 30cm is the difference between broken and unbroken sleep. If your room is under 3m x 2.9m, the UK king fits better and needs at least 2.7m x 2.9m.
How much space does each person get on a super king?
90cm each for two people sharing, which is the same width as a whole UK single per person. On this mattress that space is genuinely usable, because the Unicased edge support keeps the sides firm rather than letting them dip when you sleep near the perimeter.
Will a super king Sealy Perfection Plush get up my stairs?
It's the trickiest size to move: 6ft x 6ft 6in in one piece, with a sprung core that won't fold. Tight landing turns and loft conversion staircases are the usual failure points, so measure the route, including any low ceilings, before ordering.
