Key Benefits of the Sealy Posturepedic Elevate Bentham King Size Mattress

  • Room to sink in side by side: A soft mattress lets you settle into it, and 75cm each gives two side sleepers enough width to curl up without knees or elbows meeting in the middle.
  • Length for taller partners: At 200cm, or 6ft 6in, the UK king is 10cm longer than a UK double, so a partner over six foot is far less likely to have feet hanging off the end.
  • Space between different schedules: If one of you is up hours before the other, the extra 15cm of width over a UK double puts a little more distance between the early riser and the person still asleep.
  • Room for extra pillows: During pregnancy or recovery from surgery, a wedge or body pillow takes up real space, and a UK king leaves enough width for it without pushing your partner to the edge.
  • Standard bedding fits: King sheets and a 230 x 220cm king duvet suit this mattress, so you won't need to hunt for unusual sizes.

Who should buy the Sealy Posturepedic Elevate Bentham King Size Mattress?

This size suits you if...

You share the bed every night and keep bumping into each other on a UK double, one of you is over six foot and needs the extra length, or you like a soft, cushioned feel and want enough width for both of you to sink in comfortably.

Consider another size if...

Your bedroom falls short of our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m, or the UK super king, giving 90cm each, if you have 3m x 2.9m.

FAQ's

Frequently Asked Questions About the UK King

Is the Sealy Bentham UK king big enough for two people?

For most couples, yes. A UK king gives 75cm each, which is 7.5cm more each than a UK double. On a soft mattress like this one, that extra width helps, because you each sink into your own space rather than meeting in the middle. If you want more room than that, the UK super king gives 90cm each.

Is a UK king mattress long enough if you're over six foot?

It's 200cm long, which is 6ft 6in, and 10cm longer than a UK double. That extra length is often the real reason taller couples size up, since a UK double can leave feet near or over the end. For a partner over six foot, the UK king gives noticeably more breathing room at the foot of the bed.

What size bedroom do I need for a Sealy Bentham king size mattress?

We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. Measure once wardrobes and drawers are in place, because new build bedrooms often feel smaller after furniture goes in. If your room falls under our minimum, the UK double needs at least 2.6m x 2.8m.

What duvet and sheets fit a Sealy Bentham UK king?

King sheets fit the 150 x 200cm mattress, and a 230 x 220cm king duvet suits it. Because UK king is a standard size, bedding is easy to find. Sealy doesn't publish a depth for this mattress, so check fitted sheet pocket depth against the retailer's listing before you buy.

Should I choose the Sealy Bentham in a UK king or UK super king?

The UK king suits most couples with a room of at least 2.7m x 2.9m, and gives 75cm each. The UK super king is the same length but gives 90cm each, so it's the better pick if a dog shares the bed or you want maximum distance, provided you have at least 3m x 2.9m.
