1. An apparatus for supporting the feet of an occupant of a chair with the feet above a floor level, said apparatus comprising: a base having a front, a rear, and two sides, said base having a top surface;a toe pocket attached to said front of said base, said toe pocket extending upwards from said top surface, said toe pocket having an opening facing said rear of said base;a heel stop extending substantially perpendicular from said top surface at said rear of said base; anda pair of straps each extending from each one of said two sides of said base, said pair of straps configured to attach to the chair such that said base is suspended above the floor;whereby said base accommodates the feet of the occupant while the occupant is seated in the chair; andwherein said pair of straps are attached to said base with a pair of strap supports, each one of said strap supports having a first support side and a second support side opposite said first support side, each one of said first support sides attached to one of said two sides of said base, said first support side having a length at least one-half a distance between said front and rear of said base, and said second support side being substantially centered between said front and rear of said base. 2. The apparatus of claim 1 wherein each one of said pair of straps have a buckle with each one of said pair of straps having a loop formed with said buckle. 3. The apparatus of claim 1 wherein said pair of straps each have a buckle separating said each one of said pair of straps into two sections, and each said buckle releasably connecting said two sections. 4. The apparatus of claim 1 wherein each one of said pair of straps include a loop at an end distal to said two sides of said base, each said loop configured to attach to the chair. 5. The apparatus of claim 1 further including a stiffener positioned proximate said opening of said toe pocket, and said stiffener configured to keep an upper wall of said toe pocket above said top surface of said base. 6. The apparatus of claim 1 wherein said base includes a stiffener that maintains said base in a substantially planar configuration with said apparatus in a deployed position wherein said base is suspended from the chair. 7. The apparatus of claim 1 further including a pair of extensions configured to attach to the chair, each one of said pair of extensions receiving a distal end of a corresponding one of said pair of straps. 8. An apparatus for supporting the feet of an occupant of a chair with the feet above a floor level, said apparatus comprising: a platform having a base and a back rest, said base having a pair of sides in opposing relationship;a pair of straps of a flexible material, each one of said straps having a proximal end attached to one of two sides of said base;a pair of attachment members each configured to attach to a member of the chair; anda distal end of each one of said pair of straps attached to a corresponding one of said pair of attachment members, such that said platform is operable to transition between a stored position and an open position when said pair of attachment members are attached to the chair; anda pair of strap supports in which each one of said strap supports is attached to a corresponding one of said pair of sides, said pair of straps attached to a corresponding one of said pair of strap supports, each one of said strap supports having a first support side and a second support side opposite said first support side, said first support side having a length at least one-half a distance between said front and rear of said base, and said second support side being substantially centered between said front and rear of said base. 9. The apparatus of claim 8 wherein said platform has a magnetic attraction for a clip configured to be attached to the chair, and when said clip is attached to said chair said platform is suspended from said clip when said platform is in said stored position. 10. The apparatus of claim 9 wherein said clip attaches to a bottom of a seat of the chair. 11. The apparatus of claim 8 further including a toe pocket on said base, said toe pocket proximate a front of said base. 12. The apparatus of claim 11 wherein said toe pocket has an opening that is supported above said base by a stiffener. 13. The apparatus of claim 8 wherein said platform includes a stiffener that maintains said base in a substantially planar configuration with said platform in said deployed position. 14. An apparatus for supporting the feet of an occupant of a chair with the feet above a floor level, said apparatus comprising: a platform having a base and a back rest, said base having a pair of sides in opposing relationship;a pair of straps of a flexible material, each one of said straps having a proximal end attached to one of two sides of said base; anda pair of attachment members each configured to attach to a member of the chair, a distal end of each one of said pair of straps attached to a corresponding one of said pair of attachment members wherein when said pair of attachment members are attached to the chair said platform is movable between a stored position and a deployed position;a pair of strap supports in which each one of said strap supports is attached to a corresponding one of said pair of sides, said pair of straps attached to a corresponding one of said pair of strap supports, each one of said strap supports having a first support side and a second support side opposite said first support side, said first support side having a length at least one-half a distance between said front and rear of said base, and said second support side being substantially centered between said front and rear of said base;a first magnetic member attached to said platform; anda second magnetic member configured to attach to the chair, said first magnetic member and said second magnetic member having a magnetic attraction therebetween such that said second magnetic member supports said platform in said stored position when said first and second magnetic members are engaged. 15. The apparatus of claim 14 wherein said second magnetic member includes a pin configured to engage a bottom of a seat of the chair. 16. The apparatus of claim 14 further including a toe pocket opposite said back rest on a front of said base, said toe pocket configured to receive the toes of the occupant of the chair when said platform is in a deployed position. 17.
