Each sheet-attachment assembly includes a clamping apparatus adjustable by a user between a first configuration and a second configuration, and an anchor member adapted to engage the one or more sheets. The clamping apparatus is adapted to receive at least a portion of the anchor member and the one or more sheets when in the first configuration, and to clamp the one or more sheets to the anchor member when in the second configuration.

Abstract: A corner guard configured to attach to and protect the corner of a mattress foundation, as well as to receive selected ornamentation. The corner guard includes an impact-resistant core and a cover that overlies at least at portion of the core. In one embodiment of the invention, the cover is constructed of fabric and may be ornamented with patterns or indicia by a variety of techniques. The cover ensures that the ornamentation will not be damaged even if the corner guard must be bent to match the shape of the mattress foundation. Optionally, a foam layer may be positioned between the core and the cover to impart a quilted texture and appearance to the corner guard, and to provide additional padding for the mattress foundation.
