These are Zip and Link mattress pairs. Each product shown here comprises a pair of identical mattresses, which are zipped along facing top edges.
This allows them to be used as 2 single mattresses on single beds, or to be zipped together and used as one King size or Superking size mattress on two suitable beds pushed against each other. (Check out our range of Zip and Link beds.)
These mattresses also provide an excellent way of getting a King or Superking size mattress into a bedroom where stair or passage access prevents the delivery of a single-piece mattress in such a large size.
All the mattress available here as Zip and Link pairs are also available as single items without zips in our standard mattress range.
