Key Benefits of the Hyde & Sleep Refine Air Foam King Size Mattress

  • More room each than a double: You get 75cm each in a UK king against 67.5cm in a UK double, which means fewer elbows and more space to turn over without waking your partner.
  • Length for taller sleepers: At 200cm, the UK king is 10cm longer than a UK double, which matters most when one of you is over six foot and keeps running out of mattress.
  • Responsive foam for shared beds: The Aurora foam pods give a bouncy rather than slow-sinking feel, so changing position should be easier, and the extra width of a UK king gives each of you a little more room to do it.
  • Breathable across a wider surface: The open-cell airflow foam and knitted cover are designed for breathability, which suits couples where one partner finds all-foam beds warm.
  • Zoned support on both sides: The 3-zone profiled base is shaped for shoulders, back and hips, and on a UK king each sleeper has enough width to stay over their own zoned area.

Who should buy the Hyde & Sleep Refine Air Foam King Size Mattress?

This size suits you if...

You share the bed every night and wake when your partner gets up hours before you, one of you is over six foot and tired of feet hanging off a UK double, or you want a medium all-foam feel with a little bounce in a size that leaves each person proper room.

Consider another size if...

Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Hyde & Sleep Refine Air Foam UK king big enough for two people?

For most couples, yes. A UK king gives 75cm each, which is 7.5cm more per person than a UK double. If your partner sprawls, or a dog regularly claims the middle, the UK super king gives 90cm each, although it needs a room of at least 3m x 2.9m.

How big is a Hyde & Sleep Refine Air Foam king size mattress in feet?

The UK king version measures 5ft x 6ft 6in, or 150 x 200cm. It is 25cm deep, so check that your sheets have deep enough pockets.

What size room do I need for a UK king Refine Air Foam mattress?

We suggest allowing at least 2.7m x 2.9m for a UK king, and 3.2m x 3.2m is comfortable. New build master bedrooms often feel smaller once fitted wardrobes and bedside tables are in, so measure the floor space you will actually have left, then compare the retailers listed on this page.

Will a taller person fit on the Refine Air Foam in a UK king?

The UK king is 200cm long, 10cm more than a UK double or UK small double. That extra length is often the real reason to upgrade when one partner is approaching or over six foot. The UK super king is the same length, so it only adds width.

Should I get the Refine Air Foam in a UK king or UK double if my partner gets up early?

If one of you leaves hours before the other, the UK king's extra 7.5cm each puts a little more distance between you as they get up. The medium, bouncy foam feel is the same in both sizes, so the choice comes down to space and whether your room fits a UK king.
