UK Long Small Double Mattresses

The UK long small double (120 x 200cm) gives a solo sleeper generous width and the full 200cm length, without the footprint of a double.

Why choose a long small double?

  • It has the full 200cm length of a king in a width that suits one person.
  • At 120cm wide there's plenty of room for a single sleeper, and space for two at a pinch.
  • It takes 15cm less width than a standard double, which helps where a room is tight across.
  • It shares its footprint with the continental 120 x 200cm size, so European frames built to that size fit.

Allow at least 2.4m x 2.9m; use 120 x 200cm fitted sheets from continental ranges, with a double duvet.

How big is a long small double mattress?

120 x 200cm: small double width with an extra 10cm of length.

Who is it for?

Taller solo sleepers who want space without moving to a full double footprint.

What bedding fits?

120 x 200cm fitted sheets from continental or specialist ranges, with a double duvet on top.

Can two people share a long small double?

For the odd night, yes. Each person gets 60cm of width, less than a small single each, so most couples find a double or king more comfortable for every night.

Will it fit a standard small double frame?

No. A standard UK small double frame is built for a 190cm mattress, so you need a frame with a 200cm internal length.
