Key benefits

Key Benefits of the Sleepeezee Serene 1000 King Size Mattress

  • Space to settle apart: The UK king is 15cm wider than a UK double, which means a little clear space between you, so knees and elbows stop meeting in the small hours.
  • Gentler on early starts: If one of you is up hours before the other, independently moving springs across the UK king's width help stop that rise from rolling across to the sleeping side.
  • Length for a tall partner: At 200cm, the UK king is 10cm longer than a UK double, so a partner over six foot is far less likely to have heels hanging off the end.
  • A smaller footprint than the UK super king: We suggest allowing at least 2.7m x 2.9m for a UK king, compared with the 3m x 2.9m we suggest for the UK super king.
  • Some help with shared heat: Two people generate more warmth than one, and the graphite in the memory foam layer is there to help draw some of that heat away.

Who should buy the Sleepeezee Serene 1000 King Size Mattress?

This size suits you if...

You share the bed every night and a UK double leaves you nudging each other, one of you gets up long before the other and you'd rather not wake them, or one partner is tall enough that an extra 10cm of length would finally stop their feet reaching the edge.

Consider another size if...

Your bedroom falls short of our suggested 2.7m x 2.9m once the wardrobes are in. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Sleepeezee Serene 1000 UK king big enough for two adults?

For most couples, yes. A UK king gives you 75cm each, which is 7.5cm more each than a UK double. If you both sprawl, or a dog regularly claims the middle, the UK super king gives 90cm each, though it needs a larger room.

Is a UK king Serene 1000 long enough if you're over 6ft?

It's 200cm long, or 6ft 6in, which is 10cm longer than the UK double. That extra length is often what a tall sleeper notices first. The UK super king is exactly the same length, so sizing up beyond the UK king only buys you width.

Will I feel my partner move on a king size Serene 1000?

You should feel less than on a UK double. Pocket springs move individually rather than as one unit, and the UK king puts 15cm more width between you. Neither removes movement entirely, but together they make a partner's late return or early alarm a little easier to sleep through.

Serene 1000 UK king or UK super king for a couple?

The UK king is 30cm narrower than the UK super king, giving 15cm less each. In return it fits a smaller room: we suggest at least 2.7m x 2.9m for the UK king against 3m x 2.9m for the UK super king. If your room is borderline, choose the UK king.

Will a UK king Serene 1000 fit a new build master bedroom?

Measure after the fitted wardrobes are in, because new build rooms often shrink once storage is added. We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m giving comfortable room to walk around the bed and open doors.
