Key benefits

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

  • Distance from a restless partner: With 90cm each for two people sharing, a partner who turns all night sits far enough away that you're less likely to feel every move.
  • Room when the family piles in: When a child arrives in the small hours or a large dog settles at the foot, the 180cm width means nobody ends up clinging to the edge.
  • More each than the UK king: Compared with the UK king, the UK super king gives 15cm more each, which can be the difference between brushing elbows and sleeping undisturbed.
  • Summer side for a crowded bed: Extra bodies add warmth, so on warm nights with children sharing, the summer side across the full 180 x 200cm helps keep everyone a little cooler.
  • Right proportions for a large room: In a period house or a generous master bedroom, a 6ft x 6ft 6in mattress fills the space properly where a UK king can look slightly lost.

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

This size suits you if...

You share with a partner who tosses and turns and want real space between you, or children and dogs regularly end up in your bed and everyone still needs a fair share of the mattress.

Consider another size if...

Your bedroom is under our suggested 3m x 2.9m minimum, or your stairs and landing are tight. 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

What room size do I need for a Flaxby Silkstone super king mattress?

We suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable once bedside tables and walking space are added. In a loft conversion, check the slope first: the bed usually needs the wall with full head height, which can rule out a UK super king even when the floor measurements look fine.

Is a super king big enough for two adults and a child?

It's the most room you'll find in a standard UK size, with 90cm each for two adults before a child climbs in. A small child in the middle will still squeeze you slightly, but noticeably less than on a UK king, which gives 75cm each.

How hard is it to turn a UK super king dual season mattress?

Using the summer and winter sides means turning the mattress as the seasons change, and at 180 x 200cm and 39cm deep, that's a job for two people. Clear space around the bed before you start, and plan for it rather than attempting it alone.

Will a Flaxby super king mattress fit up my stairs?

Measure the narrowest points before ordering: doorways, the turn on the landing and any low ceiling over the stairs. At 180cm wide and 39cm deep, tight landing turns are where a UK super king is most likely to get stuck. Once you're sure it fits, compare the retailers listed on this page.

What bedding fits a 39cm deep UK super king mattress?

You'll need super king sheets and a 260 x 220cm duvet. At 39cm deep, look for deep or extra-deep fitted sheets, as standard ones may struggle to stay on the corners. Super king bedding also costs more than smaller sizes, so factor that in alongside the mattress.
