Key benefits
- 90cm of width each: Each sleeper gets 15cm more width than on the UK king, which means a partner who turns over all night is noticeably further from you.
- Room for night-time visitors: If a small child pads in after a bad dream, the 180cm width leaves space for them without either adult being pushed to the edge.
- Wider, no longer: It's the same 200cm length as the UK king, so you gain 30cm of width while only needing a slightly wider room.
- Natural filling over a big surface: Swaledale wool with no foam or glue runs across the whole 180 x 200cm footprint, which suits you if you'd rather avoid a large area of synthetic padding.
- In proportion in a large room: In a high-ceilinged period bedroom or a generous master, the 6ft width looks settled where a UK king can leave the room feeling half furnished.
This size suits you if...
You share the bed with a partner whose tossing and turning wakes you, children or a large dog regularly join you overnight, or your bedroom comfortably clears our suggested minimum of 3m x 2.9m and you want the bed to fill it properly.
Consider another size if...
Your bedroom is smaller than 3m x 2.9m, 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
How big a bedroom do I need for a Flaxby Woolcroft 3500 super king?
We suggest at least 3m x 2.9m, which leaves room to walk around the bed and open drawers. At 33cm deep and 6ft wide, getting it upstairs is the other check: measure the door swing and any tight landing turns first, then compare the retailers listed on this page.
Is a UK super king Woolcroft 3500 big enough for two adults and a child?
For two adults it gives 90cm each, which is generous. A young child climbing in takes a share of that, so nobody has the full 90cm, but there's usually still space for everyone to sleep. If it happens every night with older children, expect it to feel a little busier.
Woolcroft 3500 super king vs king: is the extra width worth it?
The UK super king is 30cm wider than the UK king and the same length, giving each of you 15cm more. That matters most with a restless partner or regular visitors in the bed. If your room is under 3m x 2.9m, the UK king, at a suggested 2.7m x 2.9m, is the more comfortable fit.
What size bedding fits a UK super king Woolcroft 3500?
Buy super king sheets and a 260 x 220cm duvet. The mattress is 33cm deep, so choose fitted sheets with deep pockets, as shallow ones can slip off the corners. Super king bedding sets are a larger outlay than UK king ones, so factor that in.
Will a UK super king fit in a loft conversion bedroom?
Often, but the sloping ceiling usually decides which wall the bed goes against. Place the 6ft 6in length where you'll have headroom to sit up, and check there's still clear floor beside it. Our suggested minimum of 3m x 2.9m applies to usable floor, not space tucked under the slope.
