Key benefits

Key Benefits of the Hyde & Sleep Original Memory Foam King Size Mattress

  • A little more room each: The UK king gives 7.5cm more each than the UK double, so a restless partner's turns land slightly further from you.
  • Length for a taller partner: At 200cm, the UK king is 10cm longer than the UK double, so someone approaching 6ft can stretch out without their feet reaching the edge.
  • Kinder to early risers: If one of you gets up hours before the other, a memory foam surface that moulds to each sleeper may make that early exit slightly less noticeable.
  • Space when sleep changes: During pregnancy or recovery, the UK king leaves room for a support pillow or a shifted position without pushing your partner towards the edge.
  • Fits more bedrooms than a super king: We suggest a room of at least 2.7m x 2.9m, which is less floor space than we recommend for the UK super king.

Who should buy the Hyde & Sleep Original Memory Foam King Size Mattress?

This size suits you if...

You share the bed every night and keep nudging each other on a UK double, one of you is approaching 6ft and tired of feet at the edge, or your schedules differ and you'd like a bit more distance from an early riser.

Consider another size if...

Your bedroom is under our suggested 2.7m x 2.9m, or you both want far more room than 75cm each. We'd recommend the UK double for smaller rooms (at least 2.6m x 2.8m) or the UK super king for more space.

FAQ's

Frequently Asked Questions About the UK King

Is a UK king Hyde & Sleep Original Memory Foam Mattress big enough for two?

For most couples, yes. A UK king gives 75cm each, compared with 67.5cm each on a UK double, so you gain 7.5cm of personal space. If you both sprawl, or a dog joins you most nights, the UK super king gives 90cm each, which is 15cm more per person than the UK king.

What size bedroom do I need for a UK king memory foam mattress?

We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m giving comfortable room to move around. New build master bedrooms often feel smaller once wardrobes go in, so measure with furniture in place, then compare the retailers listed on this page.

Is a UK king long enough for a tall partner?

At 200cm, a UK king is 10cm longer than a UK double, a real difference for anyone approaching 6ft. It's the same length as the UK super king, so if height is your main reason for upgrading, the UK king gives you the extra length without the wider footprint.

What bedding fits a UK king mattress?

Look for king sheets and a 230 x 220cm king duvet. The Hyde & Sleep Original is 23cm deep, so check the pocket depth on any fitted sheet covers that comfortably before you buy.

Should I get the Hyde & Sleep Original in a UK king or a UK super king?

The UK king is 30cm narrower than the UK super king but the same length, giving 15cm less space each. Choose the UK super king if a regular canine guest or very different sleep positions leave you short of room, and your bedroom meets our suggested 3m x 2.9m.
