Key benefits

Key Benefits of the Flaxby Natural Cashmere Vale 15750 King Size Mattress

  • More room each: A UK king gives 75cm per person, 7.5cm more each than a UK double, so elbows and knees meet a little less often.
  • Length for taller sleepers: At 200cm, or 6ft 6in, the UK king is 10cm longer than a UK double, which means feet stay on the mattress rather than off the end.
  • Easier on mismatched routines: If one of you is up before dawn, the extra width puts a bit more distance between you as they climb out in the dark.
  • Space without a super king footprint: You get more personal room than a UK double, and we suggest at least 2.7m x 2.9m, against 3m x 2.9m for the UK super king.
  • Seasonal flipping across a wide surface: Both sleepers get the cashmere and alpaca side in winter and the cotton and mohair side in summer, although flipping a UK king is a two person job.

Who should buy the Flaxby Natural Cashmere Vale 15750 King Size Mattress?

This size suits you if...

You share the bed every night and wake up feeling hemmed in on a UK double, or one of you is over six foot and keeps running out of mattress. It also helps if your working hours don't line up and someone is always getting up while the other sleeps.

Consider another size if...

Your bedroom falls short of our suggested 2.7m x 2.9m once wardrobes are in. 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 Cashmere Vale UK king big enough for two adults?

For most couples, yes. A UK king gives you 75cm each, which is 7.5cm more per person than a UK double. That's enough to notice on the nights you'd usually be nudged awake. If one of you sprawls, or a dog shares the bed, the UK super king's 90cm each may suit you better.

Is a UK king Flaxby Cashmere Vale long enough if I'm over 6ft?

The UK king is 200cm long, or 6ft 6in, which is 10cm longer than a UK double. For anyone around six foot, that extra length is often the reason to upgrade, more so than the width. The UK super king is the same length, so going larger only adds width.

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

We suggest at least 2.7m x 2.9m for a UK king, with 3.2m x 3.2m feeling comfortable. New build master bedrooms can look generous empty and then shrink once fitted wardrobes go in, so measure with the doors open before you compare the retailers listed on this page.

Can one person flip the Flaxby Cashmere Vale in a UK king?

Plan on two of you. At 150cm wide and 35cm deep, the UK king is an awkward shape for one person to turn over, and you'll want to flip it twice a year to switch between the winter and summer sides. Remove the mohair pillow top first so there's less to wrestle with.

Should I get the Flaxby Cashmere Vale in a UK king or a UK super king?

Choose the UK king if you want more space than a UK double without giving up floor space. The UK super king is 30cm wider and gives 90cm each, 15cm more per person, but we suggest at least 3m x 2.9m for it. Both are 200cm long.
