Key benefits

Key Benefits of the Sealy Blakemere Geltex Enhance 1800 Pocket Pillow Top King Size Mattress

  • More room each than a UK double: The UK king gives 7.5cm more each than the UK double, which means a little extra breathing space between you on a cushioned pillow top surface.
  • Length for taller partners: It is 10cm longer than the UK double, so a partner over six foot can stretch out without their heels resting on the edge.
  • Calmer nights on different schedules: Pocket springs move individually, which helps if one of you rises hours before the other, and the 75cm each gives the early riser room to slip out.
  • Space for extra pillows: During pregnancy and the months after, the UK king leaves room for a support pillow and frequent position changes without crowding the other sleeper.
  • A middle ground on room size: The UK king is 30cm narrower than the UK super king, which suits a master bedroom that feels tighter once the wardrobes are in.

Who should buy the Sealy Blakemere Geltex Enhance 1800 Pocket Pillow Top King Size Mattress?

This size suits you if...

You share the bed every night and keep waking each other on a UK double, one of you is tall enough that the extra length matters more than the width, or your schedules differ and you want enough space for one partner to get up quietly.

Consider another size if...

Your bedroom is under our suggested 2.7m x 2.9m, or a dog regularly claims its share of the bed. For a smaller room we'd recommend the UK double, for which we suggest at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Sealy Blakemere Geltex Enhance 1800 UK king big enough for two people?

Yes, for most couples. The UK king gives 75cm each for two people sharing, and the pocket springs help limit how much one partner's movement reaches the other. If you or your partner sprawl, or a pet joins you most nights, the UK super king gives 90cm each.

What size room do I need for a UK king Sealy Blakemere Geltex Enhance 1800?

We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. In a new build master bedroom, measure after fitted wardrobes are in, as they can take more floor than you expect.

How much bigger is a king size than a double for the Sealy Blakemere?

The UK king is 15cm wider and 10cm longer than the UK double. Shared between two people, that comes to 7.5cm more each, plus the extra length that helps anyone approaching six foot.

Is a king size Sealy Blakemere Geltex Enhance 1800 long enough for tall people?

The UK king measures 200cm long, which is 10cm longer than the UK double and the UK small double. If one partner is over six foot, that extra length is often the real reason to size up. The UK super king is the same length, so it only adds width.

What bedding fits the Sealy Blakemere Geltex Enhance 1800 king size?

Standard king sheets fit the 150 x 200cm footprint, and a 230 x 220cm king duvet suits it. The mattress is 27cm deep with a pillow top, so check that fitted sheets list a pocket depth that will tuck under comfortably before you buy.
