A bed with linen changing means comprises features that allow the mattress linen to be changed without requiring an occupant to leave the bed. The bed frame provides a matrix of parallel slats which support the occupant while the mattress is lowered and extended for linen changing. The mattress comprises a plurality of parallel horizontal mattress sections spaced apart allowing corresponding insertion between the slats until said slats are recessed within the mattress and a user is able to lie comfortably upon raised portions of the mattress. The mattress is supported by a mobile frame apparatus being vertically adjustable via a manually-operated crank and gear assembly such that a caretaker may lower the mattress while the bed occupant rests upon the slats, providing easy access to the mattress for purposes of changing bed linens. The mattress is then raised back into place to support the occupant.
