King size zip and link mattress
A king size zip link mattress is the same overall size as a standard kingsize. 5'0 x 6'6″. The mattress is split into two, making each side 2'6″ wide and 6'6″ long. This size is practical when a bedroom size cannot accommodate a super king size mattress. If you are looking to purchase this size mattress for a guest house or b&b, keep in mind that a 2'6 wide mattress is fairly small for the average size person when separated.
Super king size zip and link mattress
A super king zip & link mattress is 6'0 x 6'6″. This is the standard size of a super king-size bed, whether a zip and link or one-piece mattress.
