5813066 - Baby rest

A baby rest for placement upon a support surface employs a generally C-shaped inflatable tube member surrounded by padding, the combination of the tube member and padding encased in a generally circular outer fabric cover. The outer cover substantially traverses the center area of the C-shaped tube, thereby creating a thinly padded, central rest area on which an infant may lie. The tube member can be inflated to varying degrees, such that the tube member and the surrounding padding create a peripheral guard around the center rest area of sufficient height to prevent an infant from rolling out of the proportionally smaller rest area.

A fancifully-shaped crib bumper having stuffed legs serving in the traditional role of a crib bumper, as well as stuffed arms that provide added protection higher up on the side of a crib. The tubular arms and legs of the novel crib bumper are stuffed by using rolled fiberfill batting, which is placed in an insertion device that may be either preformed in a tubular shape or may comprise a flexible sheet material that is rolled around the rolled fiberfill batting. The use of the insertion device permits the rolled fiberfill batting to be inserted into a crib bumper leg or arm in a simple, easy manner, and is then removed, leaving the fiberfill batting in place. The fiberfill batting is then securely attached to the outer casing of the crib bumper by stitching.
