Key benefits
- More room each than a double: Sharing a UK king gives you 7.5cm more each than the UK double, so elbows and knees meet your partner less often through the night.
- Length for taller partners: At 200cm long, the UK king is 10cm longer than the UK double, which means a partner over six foot can stretch out without feet reaching the edge.
- Separate springs, separate sleep: Pocket springs move individually, which means one partner turning over or getting up early disturbs the other a little less across the wider surface.
- Firm across the whole width: The firm comfort grade feels the same edge to edge in a UK king, so neither side of the bed ends up softer or more sunken.
- A middle ground on space: The UK king is 30cm narrower than the UK super king, so it suits couples who want more room without giving up a whole bedroom to the bed.
This size suits you if...
You share the bed every night and keep waking each other on a UK double, one of you is tall enough that 190cm feels short, or your partner leaves for work hours before you do and you'd like to sleep through it.
Consider another size if...
Your room falls short of our suggested minimum of 2.7m x 2.9m. We'd recommend the UK double instead, which we suggest needs at least 2.6m x 2.8m.

FAQ's
How much space does each person get on a Flaxby Woolcroft 3500 UK king?
Two people sharing a UK king get 75cm each. Compared with the UK double, which gives 67.5cm each, that's 7.5cm more per person. On a firm mattress like this one, where you sit on top rather than sinking in, that extra room is easy to feel when you both sleep on your backs.
Is the Flaxby Woolcroft 3500 UK king long enough for someone over 6ft?
The UK king is 200cm long, which is 10cm longer than the UK double and the UK small double. For a partner around or over six foot, that extra length gives you room to lie straight with a pillow at the top, rather than feet pressing near the end.
What size bedroom do I need for a UK king Flaxby Woolcroft 3500?
We suggest allowing at least 2.7m x 2.9m for a UK king. In a new build master bedroom, measure after fitted wardrobes go in, as they can take more floor than expected. If your room comes up short, the UK double needs at least 2.6m x 2.8m by our guidance.
Should we get the UK king or UK super king Flaxby Woolcroft 3500?
The UK super king gives 90cm each against 75cm on the UK king, so 15cm less each on the king. Both are 200cm long, so length isn't the deciding factor. If a dog shares the bed most nights, the extra width may help, but we suggest at least 3m x 2.9m for a UK super king.
What bedding fits a Flaxby Woolcroft 3500 in UK king size?
You'll need king fitted sheets, and a 230 x 220cm king duvet fits this size. The mattress is 33cm deep, so check that the fitted sheets you buy are labelled for deep mattresses, as shallower king sheets may struggle to tuck under at the corners.
