Key benefits

Key Benefits of the Sealy Winslow Geltex Enhance 2400 Pocket Pillow Top King Size Mattress

  • More room between you: With 75cm each for two sharing, you get 7.5cm more each than on a UK double, which means a little more distance from a partner who fidgets.
  • Extra length for taller sleepers: The UK king is 200cm long, 10cm longer than a UK double, so a partner over six foot is far less likely to wake with cold feet.
  • Easier on different schedules: Sealy says there's no roll-together, and on a UK king that extra width should help further when one of you gets up hours before the other.
  • The same medium feel, with space to spread out: The pillow top cushions shoulders and hips for both of you, although a bigger size won't help if either of you prefers a firm surface.
  • Standard king bedding: King sheets and a 230 x 220cm king duvet fit, though at 31cm deep you'll want fitted sheets with generous pockets.

Who should buy the Sealy Winslow Geltex Enhance 2400 Pocket Pillow Top King Size Mattress?

This size suits you if...

You share the bed every night and a UK double has started to feel cramped, one of you is over six foot and keeps running out of length, or you work different hours and want a little more distance from whoever gets up first.

Consider another size if...

Your bedroom is smaller than our suggested 2.7m x 2.9m for a UK king. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Sealy Winslow Geltex Enhance 2400 king size 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's a modest gain on paper, but it's enough to stop elbows meeting most nights. If you both sleep spread out, the UK super king gives 90cm each, as long as your room allows at least 3m x 2.9m.

Is a Sealy Winslow king size mattress long enough for someone over six foot?

The UK king measures 5ft x 6ft 6in, or 150 x 200cm, so it's 10cm longer than a UK double. For a tall partner, that length is often the real reason to size up. The UK super king is the same length, so you only need to go bigger if you also want more width.

What size bedroom do I need for a UK king mattress like the Sealy Winslow?

We suggest allowing at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. New build master bedrooms can feel smaller than their floor plan once wardrobes go in, so measure the space that's left before you order.

What duvet and sheets fit the Sealy Winslow Geltex Enhance 2400 king size?

Standard king sheets and a 230 x 220cm king duvet fit the 150 x 200cm mattress. The mattress is 31cm deep with a pillow top, so check that your fitted sheets have deep enough pockets. Shallow ones tend to ping off the corners.

How heavy is the Sealy Winslow Geltex Enhance 2400 in a king size?

Sealy doesn't publish a weight for the UK king. The UK super king weighs 63kg, so expect a heavy mattress that takes two people to rotate. It's a pillow top and can't be flipped, so rotating is the only turning you'll do. Check the brand's guidance if stairs or access are tight.
