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.

See [UK fitted sheet sizes](/sizing/uk-fitted-sheet-sizes/) and the [mattress depth guide](/sizing/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](/tools/delivery-fit-checker/), or read [bed footprint and delivery access](/sizing/bed-footprint-and-access/). ## Where can you buy a Super King bed? Each bed type page lists verified UK makers and shops, so you can compare prices: [ottoman beds](/beds/ottoman-beds/), [divan beds](/beds/divan-beds/), [pocket sprung mattresses](/mattresses/pocket-sprung-mattresses/) and [every type](/where-to-buy/). ## Frequently asked questions ### How big is a Super King bed in the UK?
