A base may be anchored under the thighs of a seated user or by the user's feet. An extendible element is adjusted in length from the base to position a platform at a height convenient for the platform to serve as a work surface or as a headrest. For the latter, a cushion is detachably attachable to the platform to serve in the manner of a pillow when the apparatus is used as a headrest. Adjustable pivot mechanisms interconnect the base and the platform with the extendible element to locate the platform at a convenient angle for its use as a headrest or work surface. Adjustable locks accommodate extension and retraction of the extendible element to locate the height of the platform relative to the base. The pivot mechanisms and adjustable locks also accommodate collapse of the apparatus by contracting the extendible element and by placing the extendible element essentially adjacent both the base and the platform. ## Claims ### Claim 1 A portable collapsible apparatus serving as either a headrest or work surface, said apparatus comprising: a) a base maintainable in position selectively by either the user's thighs or feet; b) a telescoping member attached to said base at a settable angle; and c) a platform supported by said telescoping member at a settable angle and serving as either a work surface or headrest. ### Claim 2 (depends on 1) The apparatus as set forth in claim 1 including a cushion removably attached to said platform for supporting the user's face. ### Claim 3 (depends on 2) The apparatus as set forth in claim 2 wherein said cushion includes an opening for breathing and wherein said platform includes at least one aperture generally coincident with said opening to provide an air path for the user. ### Claim 4 (depends on 3) The apparatus as set forth in claim 3 wherein said cushion includes a pocket for receiving a section of said platform to mount said cushion on said platform. ### Claim 5 (depends on 4) The apparatus as set forth in claim 4 wherein said cushion is generally ring shaped. ### Claim 6 (depends on 4) The apparatus as set forth in claim 4 wherein said cushion includes a ring-like element of foam material and a removable cover extending about said element of foam material. ### Claim 7 (depends on 6) The apparatus as set forth in claim 6 wherein said pocket is formed by said cover. ### Claim 8 (depends on 1) The apparatus as set forth in claim 1 including a first pivot mechanism interconnecting said base with said telescoping member and a second pivot mechanism interconnecting said telescoping member with said platform. ### Claim 9 (depends on 8) The apparatus as set forth in claim 8 wherein each of said first and second pivot mechanisms is lockable to establish the respective settable angles. ### Claim 10 (depends on 9) The apparatus as set forth in claim 9 wherein said first pivot mechanism accommodates pivotal movement of said telescoping member to a location adjacent said base and wherein said second pivot mechanism accommodates pivotal movement of said telescoping member to a location adjacent said platform to collapse said apparatus. ### Claim 11 (depends on 10) The apparatus as set forth in claim 10 wherein said telescoping member is collapsible to locate said base and said platform in proximity to one another when said apparatus is in the collapsed state. ### Claim 12 (depends on 1) The apparatus as set forth in claim 1 wherein said telescoping member includes a plurality of segments extendible and retractable with respect to one another. ### Claim 13 (depends on 12) The apparatus as set forth in claim 12 including a selectively actuatable lock for locking one of said segments with an adjacent one of said segments to maintain said telescoping member at a selected length. ### Claim 14 (depends on 13) The apparatus as set forth in claim 13 including a plurality of said actuatable locks, one of said actuatable locks being disposed at an open end of each of said telescoping member. ### Claim 15 A portable collapsible apparatus serving as either a headrest or work surface, said apparatus comprising: a) a base maintainable in position selectively by either a user's thighs or feet; b) an extendible element attached to said base at a settable angle; and c) a platform supported by said extendible element at a settable angle and serving as either a work surface or headrest. ### Claim 16 (depends on 15) The apparatus as set forth in claim 15 including a headrest, said headrest including a cushion having an opening therein and removably attached to said platform for supporting the user's face, said platform including at least one aperture generally coincident with said opening to provide a passageway for the user's breathing. ### Claim 17 (depends on 16) The apparatus as set forth in claim 16 wherein said cushion is of compressible material to softly cradle the user's head and including a cover for said material, said cover including a pocket for partially receiving said platform to maintain said cushion removably secured to said platform. ### Claim 18 (depends on 16) The apparatus as set forth in claim 16 including a first pivot mechanism interconnecting said base with said extendible element and a second pivot mechanism interconnecting said extendible element with said platform, each of said first and second pivot mechanisms being lockable to establish and maintain the respective settable angles. ### Claim 19 (depends on 18) The apparatus as set forth in claim 18 wherein said first pivot mechanism accommodates movement of the extendible element to a location adjacent said base and wherein said second pivot mechanism accommodates'pivotal movement of said extendible element to a location adjacent said platform to collapse said apparatus. ### Claim 20 (depends on 15) The apparatus as set forth in claim 15 wherein said extendible element includes at least one actuatable lock for locking said extendible element in a selected extended or collapsed length.
