Key benefits

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

  • Distance from a restless partner: With 90cm each, a partner who turns all night sleeps a full UK single's width away, and that distance does more to limit disturbance than any comfort layer.
  • Room when children or dogs join: If small children climb in or a large dog sleeps across the foot most nights, the 180cm width means the adults still keep a usable share.
  • Wider than a UK king, same length: Compared with the UK king, you gain 30cm of width and 15cm more each for two sharing, with no extra length to find room for.
  • Seasonal sides across the whole bed: The cashmere and alpaca winter side and the cotton and mohair summer side span the full 6ft x 6ft 6in, so you both sleep on the same seasonal surface.
  • In proportion in a large room: In a period master bedroom with high ceilings, a 6ft wide bed looks settled where a UK king can seem slightly lost.

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

This size suits you if...

You share with a partner who moves a lot and want real distance between you, or children or a dog regularly end up in the bed with you. Your bedroom should also comfortably clear our suggested minimum of 3m x 2.9m.

Consider another size if...

Your bedroom falls short of 3m x 2.9m, or you would struggle to flip a mattress this wide each season. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's

Frequently Asked Questions About the UK Super King

Is the Flaxby Cashmere Vale super king big enough for two adults and a child?

For a young child who wanders in at night, usually yes. The UK super king measures 180 x 200cm and gives each adult 90cm, so a small child can settle between you without anyone ending up on the edge. Older children taking up more room will make it feel closer, although still more manageable than a smaller bed.

What room size do I need for a UK super king Flaxby Cashmere Vale?

We suggest at least 3m x 2.9m. Measure with the door's full swing and your bedside tables in place, because those are what make a room feel cramped. In a loft conversion, the sloping ceiling often decides which wall the bed can go against, so check you have standing height on both sides.

Should I choose the UK king or UK super king Flaxby Cashmere Vale?

The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each for two sharing. If disturbance from a partner, children or pets is the main problem, that extra width helps. If your room is tight, the UK king needs at least 2.7m x 2.9m by our guidance.

Is a super king Flaxby Cashmere Vale hard to flip?

It takes some effort. At 180cm wide and 35cm deep, turning it over for the change of season is a two-person job, and a little harder than on the smaller sizes. Before you start, clear the floor along both long sides of the bed so you each have room to stand and lift.

Will a super king mattress fit up my stairs and into the bedroom?

A 6ft wide mattress is the size most likely to catch on tight landing turns and narrow doorways, especially in older houses. Measure the narrowest point on your route, then compare the retailers listed on this page. Remember to budget for super king sheets and a larger duvet too.
