Key benefits

Key Benefits of the Flaxby Natural Silkstone Lambswool Dual Season 13750 King Size Mattress

  • More personal space than a double: Each of you gets 75cm of width in the UK king, 7.5cm more than the UK double, so turning over is less likely to land you on your partner's side.
  • Room for different bedtimes: If one of you is up hours before the other, the extra width and pocket springs mean the early riser can slip out with a little less disturbance across the bed.
  • Length for taller sleepers: At 200cm long, the UK king is 10cm longer than the UK double, which gives a partner over six foot room to stretch out without feet reaching the edge.
  • Seasonal sides on a bigger bed: Both of you share the summer side or the winter side together, and at this width turning the mattress between seasons is easier with two people.
  • A deep mattress to plan around: At 39cm deep, the UK king will sit noticeably higher on your frame, so check your bed height and buy deep fitted king sheets.

Who should buy the Flaxby Natural Silkstone Lambswool Dual Season 13750 King Size Mattress?

This size suits you if...

You share the bed every night and have started to feel cramped in a UK double, or one of you is tall enough that the extra 10cm of length would make a real difference. It also suits couples on different schedules who want a little more distance between them.

Consider another size if...

Your bedroom is smaller than our suggested 2.7m x 2.9m for a UK king. We'd recommend the UK double instead, for which we suggest at least 2.6m x 2.8m.

FAQ's

Frequently Asked Questions About the UK King

Is the Flaxby Silkstone UK king big enough for two people?

For most couples, yes. The UK king gives 75cm each for two sharing, which is 7.5cm more each than the UK double. If you both spread out or a dog joins you most nights, the UK super king gives 90cm each, although it needs a larger room.

Will a 6ft sleeper fit on the Flaxby Silkstone in a UK king?

Yes. The UK king measures 5ft x 6ft 6in, or 150 x 200cm, so a six-foot sleeper has space beyond their head and feet. It's also 10cm longer than the UK double, and that length is often the main reason tall partners size up.

What size bedroom do I need for a UK king Flaxby Silkstone?

We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms can feel smaller once wardrobes are fitted, so measure from the doors and units rather than bare walls. At 39cm deep, the mattress also makes the bed sit higher in the room.

Should we get the Flaxby Silkstone in a super king instead of a king to stop disturbing each other?

If partner movement is your main complaint, the UK super king is 30cm wider and gives 90cm each, 15cm more each than the UK king. We suggest at least 3m x 2.9m for the UK super king, so it only makes sense if your room allows.

What bedding fits a 39cm deep UK king mattress?

Standard king sheets and a 230 x 220cm king duvet fit the UK king's 150 x 200cm footprint. Because the Flaxby Silkstone is 39cm deep, look for extra-deep fitted king sheets so the corners stay in place when you turn the mattress between its summer and winter sides.
