Key benefits

Key Benefits of the Flaxby Natural Flaxmoor 2500 Super King Mattress

  • Distance from a restless partner: Each of you gets 15cm more than on the UK king, which means a partner who turns over all night is further away from you.
  • Space when the family piles in: When a child climbs in at 3am, the 180cm width absorbs them in the middle rather than pushing either adult towards the edge.
  • Same length as the UK king: It keeps the 200cm length of the UK king, so taller sleepers lose nothing and the whole gain is 30cm of extra width.
  • A level surface across 6ft: Because it's rated extra firm with little give, a child or dog lying between you is less likely to sink into a hollow in the middle.
  • Bedding that covers two adults: Standard super king sheets fit, and a 260 x 220cm duvet leaves enough overhang that neither of you wakes up uncovered.

Who should buy the Flaxby Natural Flaxmoor 2500 Super King Mattress?

This size suits you if...

You share with a partner whose tossing and turning wakes you, or children and pets regularly end up in bed with you, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.

Consider another size if...

Your bedroom falls short of 3m x 2.9m, or a 180cm-wide mattress won't make it round your landing. 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

Will a Flaxby Natural Flaxmoor 2500 UK super king fit in my bedroom?

We suggest at least 3m x 2.9m for the 180 x 200cm mattress, with around 3.5m x 3.2m feeling right once bedside tables go in. In a loft conversion, the roof slope usually decides which wall the bed goes against, so check headroom where you'll sit up to read.

Flaxmoor 2500 UK super king or UK king for a restless partner?

The UK super king is 30cm wider and the same length, so each of you gets 15cm more. If your partner moves a lot, that gap matters more than any filling. If you both sleep fairly still, the UK king may be plenty, and we suggest at least 2.7m x 2.9m for it.

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

For a small child on occasional nights, usually yes. With 90cm each for the adults, a toddler in the middle takes space without forcing anyone off the edge. The extra firm surface stays fairly level, so they're less likely to roll into either of you. Regular co-sleeping with an older child gets tighter.

How big is a Flaxby Flaxmoor 2500 super king in feet?

It measures 6ft x 6ft 6in, which is 180 x 200cm. Flaxby doesn't publish a depth for this mattress, so if your frame has a deep surround or you're pairing it with a tall headboard, ask the retailer before ordering rather than assuming it will sit flush.

Will a UK super king mattress get up my stairs?

At this size the checks that catch people out are the bedroom door swing and tight landing turns, since the mattress is 180cm wide and a pocket spring build won't bend much. Measure the narrowest point and any turn on the stairs first, then compare the retailers listed on this page.
