Key Benefits of the Hyde & Sleep 360 Advance Memory Foam Rolled King Size Mattress

  • More room each: You each get 75cm of width, which means there's space to shift position or prop yourself up on pillows during pregnancy without drifting onto your partner's side.
  • Length for taller sleepers: At 200cm, or 6ft 6in, it's 10cm longer than the UK double, so a tall partner's feet stay on the mattress.
  • A little distance on early mornings: If one of you gets up hours before the other, the extra 15cm of width over a UK double puts slightly more space between you as they climb out.
  • Fits a typical main bedroom: We suggest at least 2.7m x 2.9m, so in a new build main bedroom, measure after the wardrobes are fitted rather than from the floor plan.
  • Straightforward bedding: Standard king sheets fit, and a 230 x 220cm king duvet covers two people without a nightly tug of war.

Who should buy the Hyde & Sleep 360 Advance Memory Foam Rolled King Size Mattress?

This size suits you if...

You share the bed every night and have started to feel cramped on a UK double, or one of you is near 6ft and wants the extra length as much as the extra width.

Consider another size if...

Your bedroom is smaller than 2.7m x 2.9m, or you mostly sleep alone. 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 360 Advance UK king big enough for two people?

Yes, for most couples. The UK king gives you 75cm each, which is 7.5cm more each than the UK double. That's a modest gain on paper, but you'll notice it on nights when one of you moves about a lot. If you'd like more width still, Hyde & Sleep doesn't make this mattress in a UK super king.

How long is the Hyde & Sleep 360 Advance king size mattress?

The UK king measures 200cm long, or 6ft 6in. That's 10cm longer than both the UK double and the UK single versions of this mattress, which makes it the size to choose if one of you is close to 6ft and finds your feet reaching the end of the bed.

What size bedroom do I need for a UK king Hyde & Sleep 360 Advance?

We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving you comfortable space to walk around. Measure after your wardrobes and bedside tables are in place, as a room can feel a good deal smaller once the furniture is in.

Should I get the Hyde & Sleep 360 Advance in a UK double or a UK king?

If two of you sleep in it every night, the UK king gives you 15cm more width and 10cm more length. The UK double makes sense if your room is tighter, as we suggest at least 2.6m x 2.8m for that size, compared with 2.7m x 2.9m for the UK king.

What duvet size fits a Hyde & Sleep 360 Advance UK king?

A king duvet at 230 x 220cm fits the UK king, along with standard king size sheets. If one of you tends to take more than your share of the covers, some couples size their duvet up, but a king duvet is the standard match.
