An assembly has a foldable frame member that has a folded and an unfolded orientation, a sheet material covering portions of the frame member when the frame member is in the unfolded orientation, and one or more floatation devices. The floatation devices can be attached to any number of locations, including but not limited to the sheet material, the top of the sheet material, the bottom of the sheet material, and the periphery of the frame member.

1. An assembly, comprising:a foldable frame member that has a folded and an unfolded orientation, the frame member defining a periphery for the assembly; a peripheral sleeve extending along the periphery for retaining the frame member; a sheet material covering interior portions of the periphery of the frame member when the frame member is in the unfolded orientation; a floatation device attached to the sheet material and configured in a closed loop that defines an interior space, with a portion of the sheet material extending in the interior space, and with the closed loop spaced apart from the the peripheral sleeve by another portion of the sheet material; and an inner sleeve stitched to the sheet material and spaced apart from the peripheral sleeve, with the flotation device retained inside the inner sleeve. 2. The assembly of claim 1, wherein the sheet material is divided into a first sheet portion and a second sheet portion, with the first sheet portion provided between the inner sleeve and the peripheral sleeve.3. The assembly of claim 2, further including an opening provided in the first sheet portion.4. The assembly of claim 1, wherein the frame member forms a plurality of concentric frame members when it has been twisted and folded into the folded orientation.5. The assembly of claim 1, further including an opening provided in the sheet material.6. An assembly, comprising:a single continuous foldable frame member that has a folded and an unfolded orientation, the frame member defining a periphery for the assembly; a single sheet material extending within portions of the interior of the periphery of the frame member when the frame member is in the unfolded orientation, the sheet material having a top surface and a bottom surface; and a floatation device attached to the bottom surface of the sheet material and positioned interior of the periphery, with the flotation device separate from the frame member, without any sheet material below the flotation device. 7. The assembly of claim 6, further including a peripheral sleeve extending along the periphery for retaining the frame member.8. The assembly of claim 6, wherein the frame member forms a plurality of concentric frame members when it has been twisted and folded into the folded orientation.9. The assembly of claim 6, further including another flotation device attached to the top surface of the sheet material.10. The assembly of claim 9, wherein the another floatation device comprises a plurality of separate floatation devices that are attached to the top surface of the sheet material.11. The assembly of claim 6, wherein the flotation device comprises a plurality of separate flotation devices that are attached to the bottom surface of the sheet material.12. An assembly, comprising:a foldable frame member that has a folded and an unfolded orientation, the frame member defining a periphery for the assembly; a single sheet material extending within portions of the interior of the periphery of the frame member when the frame member is in the unfolded orientation, the sheet material having a top surface and a bottom surface; and a floatation device attached to the bottom surface of the sheet material and separate from the frame member, without any sheet material below the flotation device; wherein the flotation device has the same size and shape as the sheet material. 13. An assembly, comprising:a single continuous foldable frame member that has a folded and an unfolded orientation, the frame member defining a periphery for the assembly; a single sheet material extending within portions of the interior of the periphery of the frame member when the frame member is in the unfolded orientation, the sheet material having a top surface and a bottom surface; and a floatation device attached to the bottom surface of the sheet material, with at least a portion of the floatation device attached to the bottom surface of the sheet material at a location away from the periphery; further including an opening provided in the sheet material. 14. An assembly, comprising:a foldable frame member that has a folded and an unfolded orientation, the frame member received in a peripheral sleeve that defines a periphery for the assembly and an open interior space that is devoid of a sheet of material; and a floatation device attached to the frame member and extending into the open interior space; wherein the frame member forms a plurality of concentric frame members when it has been twisted and folded into the folded orientation. 15. The assembly of claim 14, further including another floatation device attached to the frame member and extending away from the frame member.
