Key benefits

Key Benefits of the Sealy Rest Easy Plush Super King Mattress

  • 90cm each for two people sharing: Each of you gets 90cm of width, which means a partner turning over at 3am becomes far easier to sleep through.
  • Space when the family joins in: If a child wanders in at night, or a large dog treats the bed as their own, there's enough width for everyone to keep a fair share.
  • 30cm wider than the UK king: The UK super king is 30cm wider than the UK king at the same length, a difference you feel every night rather than a marginal upgrade.
  • Proportioned for larger bedrooms: In a big master or a period property, a smaller bed can look lost, while a 6ft x 6ft 6in mattress sits comfortably in the space.
  • Standard super king bedding fits: At 180 x 200cm it takes ordinary super king sheets, so you're shopping mainstream bedding ranges rather than hunting for special sizes.

Who should buy the Sealy Rest Easy Plush Super King Mattress?

This size suits you if...

You share the bed every night and one of you is a genuinely restless sleeper, or children and pets regularly join you and a UK king no longer stretches far enough. It also suits you if you have a large master bedroom where a smaller mattress would look undersized, and you can allow at least 3m x 2.9m of floor space.

Consider another size if...

Your bedroom falls short of the 3m x 2.9m we suggest as a minimum, or you'd struggle to get a 180cm-wide mattress round your landing. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Super King

What room size do I need for the Sealy Rest Easy Plush in a super king?

We suggest allowing at least 3m x 2.9m, which is our guidance rather than Sealy's. That gives you space to walk round the bed and open drawers. In a smaller room the bed will physically fit, but you'll feel it every time you make the bed or squeeze past a wardrobe.

Is the super king Sealy Rest Easy Plush too big for a couple?

Not if you value undisturbed sleep. The 180cm width gives you 90cm each, and at that distance a restless partner's movement is much easier to ignore. If your room is on the smaller side, though, the UK king gives you the same 200cm length in a 150cm width.

Will a super king mattress get up my stairs?

A 180 x 200cm mattress is the trickiest standard size to move, so measure your stairwell, landing turns and door swings before ordering. Sealy doesn't publish a weight for this mattress, so check the retailer's listing for handling details, and plan for two people to carry it.

How much wider is the super king than the double?

The UK super king is 45cm wider than the UK double and 10cm longer, a substantial jump rather than an incremental one. Coming from a double, two people sharing go from a fairly tight squeeze to a full single bed's width each, which changes how the bed feels far more than any upgrade in comfort layers would.

Does the Sealy Rest Easy Plush super king suit families sharing the bed?

It's the best size of this mattress for that. When a child climbs in during the night, or a dog settles across the foot, the 180cm width means the adults still keep a reasonable share. On any narrower size of this mattress, a third body tends to push someone to the edge.
