Who is a Super King bed for?
A Super King is as wide as two UK Singles side by side. Many are made as two zip-and-link halves, which also helps on narrow stairs.
How much room do you need for a Super King bed?
Leave about 50–60 cm to walk beside the bed and at the foot if your room allows. That is a useful target, not a rule.
| Layout | Room width | Room length |
|---|---|---|
| Both sides free | 280–300 cm | 250–260 cm |
| One side against a wall | 230–240 cm | 250–260 cm |
Add the extra size of the frame and headboard. Divan bases are usually close to the mattress size; wooden bedsteads, sleigh beds and wide headboards are bigger. Try the bed room planner with your own numbers.

What sheets and bedding fit?
Buy UK Super King sheets, cut for 180 × 200 cm. Match the fitted sheet pocket to your mattress depth. Duvets are often cut larger so they hang over the sides. See UK fitted sheet sizes and the mattress depth guide.
Will it fit up the stairs?
Measure doorways, stair width and tight turns before delivery day. Traditional spring mattresses should not be folded. Divan bases this size often come in two halves, which helps. Try the delivery fit checker, or read bed footprint and delivery access.
