What is claimed is: 1. An apparatus, comprising: a first membrane having a first portion and a second portion opposite the first portion, the first portion and the second portion collectively having a perimeter and defining a sleeve; a frame member formed from a flexible twistable material, the frame member being disposed between the first portion and the second portion within the sleeve; an inflatable bladder fixedly coupled to the first membrane, the inflatable bladder having a perimeter portion at least a portion of which is coupled proximate to the perimeter of the first membrane; and a second membrane coupled to the first membrane, the second membrane and the first membrane defining an opening therebetween, the second membrane being offset from the perimeter of the first membrane. 2. The apparatus of claim 1, wherein at least a portion of the inflatable bladder is disposed between the first membrane and the second membrane. 3. The apparatus of claim 1, wherein the inflatable bladder is a first inflatable bladder, the apparatus further comprising a second inflatable bladder. 4. The apparatus of claim 1, wherein the inflatable bladder is a first inflatable bladder, the apparatus further comprising: a second inflatable bladder, the second bladder being disposed between the first membrane and the second membrane. 5. The apparatus of claim 1, wherein the perimeter portion of the inflatable bladder substantially corresponds to the perimeter of the first membrane. 6. The apparatus of claim 1, further comprising a frame member covering, the frame member being substantially encased by the frame member covering. 7. The apparatus of claim 1, wherein the first membrane and the second membrane define a cavity therebetween, the cavity having a maximum width, the opening being configured to provide access to the cavity, a width of the opening being smaller than at least the maximum width of the cavity. 8. A method, comprising: disposing a frame member formed from a flexible twistable material between a first portion of a first membrane and a second portion of the first membrane, the first portion of the first membrane being opposite of the second portion of the first membrane, the first portion of the first membrane and the second portion of the first membrane collectively having a perimeter and defining a sleeve within which the frame member is disposed; fixedly coupling an inflatable bladder to the first membrane such that a perimeter of the inflatable bladder is proximate to the perimeter of the first membrane; and coupling a second membrane to the first membrane such that the second membrane is offset from the perimeter of the first membrane, the second membrane and the first membrane defining an opening therebetween. 9. The method of claim 8, wherein at least a portion of the inflatable bladder is disposed between the first membrane and the second membrane. 10. The method of claim 8, wherein the inflatable bladder is a first inflatable bladder, the method further comprising: disposing a second inflatable bladder between the first membrane and the second membrane. 11. The method of claim 8, wherein the first membrane and the second membrane define a cavity therebetween, the cavity having a maximum width, the opening being configured to provide access to the cavity, a width of the opening being smaller than at least the maximum width of the cavity. 12. An apparatus, comprising: a first membrane having a first portion and a second portion opposite the first portion, the first portion and the second portion collectively having a perimeter and defining a sleeve; a frame member formed from a flexible twistable material, the frame member being disposed between the first portion and the second portion within the sleeve; a first inflatable bladder fixedly coupled to the first membrane, the inflatable bladder having a perimeter portion substantially corresponding to the perimeter of the first membrane; and a second inflatable bladder fixedly coupled to the first membrane, the second inflatable bladder being offset from the perimeter of the first membrane. 13. The apparatus of claim 12, further comprising: a second membrane fixedly coupled to the first membrane, at least a portion of the second inflatable bladder being disposed between the first membrane and the second membrane. 14. The apparatus of claim 12, further comprising: a second membrane fixedly coupled to the first membrane, the first membrane and the second membrane define a cavity therebetween, the cavity having a maximum width, the first membrane and the second membrane further defining an opening configured to provide access to the cavity, a width of the opening being smaller than at least the maximum width of the cavity. 15. The apparatus of claim 12, further comprising a frame member covering, the frame member being substantially encased by the frame member covering. 16. A method, comprising: disposing a frame member formed from a flexible twistable material between a first portion of a first membrane and a second portion of the first membrane, the first portion of the first membrane being opposite of the second portion of the first membrane, the first portion of the first membrane and the second portion of the first membrane collectively having a perimeter and defining a sleeve within which the frame member is disposed; fixedly coupling a first inflatable bladder to the first membrane such that a perimeter of the first inflatable bladder is proximate to the perimeter of the first membrane; and fixedly coupling a second inflatable bladder to the first membrane such that the second inflatable bladder is offset from the perimeter of the first membrane. 17. The method of claim 16, wherein the second inflatable bladder is a pillow. 18. The method of claim 16, wherein the perimeter of the first inflatable bladder substantially corresponds to the perimeter of the first membrane. 19. The method of claim 16, further comprising: fixedly coupling a second membrane to the first membrane such that at least a portion of the second inflatable bladder is disposed between the first membrane and the second membrane. 20. The method of claim 16, further comprising: fixedly coupling a second membrane to the first membrane such that the second membrane is offset from the perimeter of the first membrane, at least a portion of the second inflatable bladder being disposed between the first membrane and the second membrane.
