One or more hooks 2104 are attached around or along one or more sides of the perimeter edge of the mattress 2100 and are configured to removably engage one or more support bars or rails 2106 attached to a child support device, such as a bassinet or a play yard 2108, in order to secure the mattress to the child support device. Alternatively, the hooks may be secured along the side(s) of the child support device and the rails secured along the edge(s) of the mattress. In still further alternative embodiments, the mattress includes loops configured to slide onto the rails.

[0054] FIGS. 22 and 23 illustrate another bassinet 2200, according to an example embodiment of the present invention. The bassinet 2200 comprises a sidewall enclosure 2202 coupled to a floor panel 2204 and is configured to be suspended within a play yard 2206 to support a mattress or forming an integral mattress and support structure. At least one fastener 2208 is coupled to the underside of the floor panel 2204 and is configured to removably engage at least one corresponding mating fastener 2210 located on the play yard 2206. For example, the fastener 2208 can be a female buckle component and the mating fastener 2210 can be a male buckle component adapted to releasably engage the female buckle component. When the fastener 2208 and mating fastener 2210 are engaged, the floor panel 2204 is pulled substantially taut, minimizing or eliminating sagging of the floor panel. Optionally, straps to which the fasteners are affixed can provide length adjustment for tightening or loosening the floor panel. In example embodiments, a plurality of releasable interengaging cooperative fastener pairs are spaced about the periphery or about one or more side(s) of the play yard and the periphery or side(s) of the floor panel at corresponding locations. For example, two or more (four are depicted) fasteners may be provided along each side edge of the support panel. In alternate embodiments, the fasteners can comprise resilient snap couplings, buckles, clips, and the like.

[0055] FIGS. 24, 25, and 26 illustrate another example embodiment of a bassinet 2400, according to the present invention. The bassinet 2400 comprises a sidewall enclosure 2402 coupled to a floor panel 2404 and is configured to be suspended within a play yard 2406. At least one reinforcing strap 2408 is coupled to the sidewall enclosure. Preferably, the reinforcing strap 2408 extends along the height of the sidewall enclosure 2402 substantially perpendicular to the floor panel 2404. In some example embodiments, the reinforcing strap 2408 terminates at or before the floor panel 2404. In other example embodiments, the reinforcing strap 2408 continues at least partially across the floor panel 2404, as shown in FIG. 26, optionally extending beneath and/or across the floor panel. A mattress 2410 adapted to support a child can be removably placed atop the floor panel 2404, or alternatively the floor panel can comprise an attached or integral mattress assembly. Example embodiments of mattress 2410 can be foldable, for example according to one or more example embodiments described herein, and the reinforcing straps 2408 can be positioned to align with and provide support to the fold lines 2412 of the mattress.

[0056] In further alternative embodiments of a bassinet according to the present invention, the bassinet comprises a sidewall enclosure coupled to a floor panel. One or more fasteners are secured to the floor panel and are configured to mate with one or more corresponding mating fasteners secured to a mattress when the mattress is positioned atop the floor panel. The fasteners and mating fasteners can be, for example, hook and loop fasteners, snaps, magnets, or another convention fastener. Alternatively, the floor panel and/or mattress can include rubber strips or other retention elements configured to prevent the mattress from sliding on the floor panel.

[0057] FIGS. 28 and 29 show a chamfered corner 2800 of a mattress panel 2802 according to another example aspect of the invention. In example embodiments, the corner 2800 comprises a living hinge, for example formed by stitching a seam between the mattress end and side, for example forming a foldable triangular tab at the corner of the mattress. When the mattress is installed into a play yard 2900, the chamfered corner 2800 folds at least partially upright to provide increased stiffening to resist rolling or curling of the end of the mattress, thereby maintaining a flatter mattress configuration than with a standard mattress corner as shown in FIG. 27. Cushioning or stiffening material within the mattress may be reduced or omitted at the fold line of the chamfered corner 2800, allowing the fabric or other outer shell material of the mattress 2802 to function as an integral hinge.

[0058] While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
