Abstract: A quick-change sheet has a top panel that is moisture proof and a bottom panel that includes portions extending under a mattress to anchor the sheet in use. The moisture proof top panel has a moisture proof layer and a soft fabric layer overlying the moisture proof layer. The two layers are joined together to form an integrated structure defining the top panel. Releasable fasteners connect the top and bottom panels and are arranged to be accessible so the top panel can be removed and replaced without disturbing either the bottom panel or the mattress.

Abstract: A composite bottom sheet or crib sheet comprises a first moisture proof panel overlying the mattress with a surface comfortable for a user and a second panel subjacent the first panel and extending under the mattress during use. Hook and loop fasteners intermesh on top of the mattress to connect the two panels and permit removal of the moisture proof panel when soiled.
