A shelf stores items and provides for organized and attractive display with ease of item access. Conforming to a defined physical environment or variable storage space optimally requires the shelf to provide for both vertical and horizontal adjustment. Here this is accomplished by a pair of legs that are telescopic (to reduce size) and can be locked at a height (vertical adjustment) by use of a pawl, pin, screw or other fastener known in the art. The shelf includes a planar surface that is comprised of a shelf portion, which is supported on each distal end by a leg extension. The leg extensions are mounted to the upper area of the legs. The leg extensions are received by the shelf portion, being movably mounted thereto. This allows for horizontal (width) adjustment. An end cover can be used to provide a flat surface that is consistent with the upper surface of the shelf portion. Feet are added to provide a more solid footing, the feet being removable and providing a mounting tab at the end of the legs and a mounting tab receiver at the opposite end of the legs. This allows for multiple shelves to be securely mounted one on the other.

A shelf as in claim 4, wherein said pawl includes a bias and said second portion includes a rack and said bias applies a force to enable engagement of said pawl and said rack.7. A shelf as in claim 6, wherein said rack is comprised of a vertical arrangement of a plurality of saw-tooth teeth, each tooth including a flat portion that is substantially horizontal when said second portion is supporting said shelf portion.8. A shelf as in claim 6, wherein said bias is a spring coil.9. A shelf as in claim 1, wherein said end cover is modifiable in length.10. A shelf as in claim 1, wherein said end cover includes a plurality of undercuts.11. A shelf as in claim 1, wherein said first leg and said second leg include a foot positioned on a distal end thereof and opposite to said shelf portion.12. A shelf as in claim 1, wherein said first leg and said second leg each include a mounting tab positioned on a distal end thereof and opposite to said shelf portion and a mounting tab receiver positioned adjacent to said shelf portion.13. A shelf as in claim 12 further comprising a pair of feet that are releasably mounted to said first leg and said second leg by said mounting tab.14. A shelf as in claim 1, wherein said leg extension and said shelf portion are movably mounted one to the other by a tongue in groove.15. A shelf as in claim 14, wherein said leg extension includes said groove and said shelf portion includes said tongue.16. An adjustable support device comprising:a pair of base legs including a mounting tab on a first end and a mounting tab receiver on a second end, positioned adjacent to one another; at least two leg extensions, a leg extension mounted to each leg and extending toward the other leg; and a shelf portion adapted to be received by said leg extensions, the shelf portion being movably mounted thereon, whereby width adjustment is enabled by varying placement of the shelf relative to said leg extensions. 17. A support device as in claim 16 wherein said base legs are adjustable in height.18. A support device as in claim 16 wherein said base legs are comprised of a first portion and a second portion being telescopically received by the first portion.19. A support device as in claim 18, further comprising a lock, releasably securing said first portion to said second portion.20. A support device as in claim 19, wherein said lock is a device selected from the group consisting of a pawl, a screw and a pin.21. A support device as in claim 20, wherein said pawl is pivotally mounted to said first portion.22. A support device as in claim 20, wherein said pawl includes a bias and said second portion includes a rack and said bias applies a force to enable engagement of said pawl and said rack.23. A support device as in claim 22, wherein said rack is comprised of a vertical arrangement of a plurality of saw-tooth teeth, each tooth including a flat portion that is substantially horizontal when said second portion is supporting said shelf portion.24. A support device as in claim 22, wherein said bias is a spring coil.25. A support device as in claim 16, further comprising an end cover, which is capable of being received by said leg extension.26. A support device as in claim 25, wherein said end cover is modifiable in length.27. A support device as in claim 25, wherein said end cover includes a plurality of undercuts.28. A support device as in claim 16, wherein said first leg and said second leg include a foot positioned on a distal end thereof and opposite to said shelf portion.29. A support device as in claim 16 further comprising a pair of feet that are releasably mounted to said first leg and said second leg by said mounting tab.30. A support device as in claim 16, wherein said leg extension and said shelf portion are movably mounted one to the other by a tongue in groove.31. A support device as in claim 30, wherein said leg extension includes said groove and said shelf portion includes said tongue.32. A method of positioning a planer surface in a specific area comprising:providing a device including: an adjustable height first leg and an adjustable height second leg positioned adjacent to the first leg; a leg extension mounted to said first leg and said second leg, and positioned substantially orthogonal thereto; an end cover, adapted to be received by said leg extensions, and a shelf portion capable of being received by said leg extension, the shelf portion being movably mounted thereon, whereby width adjustment is enabled by varying placement of the shelf relative to said leg extensions; placing said device in said specific area; adjusting the height of said first leg and said second leg to provide a preferred vertical position of said shelf portion; and adjusting the placement of said first leg and said second leg allowing said shelf portion to move relative to and yet be supported by said leg extensions. 33.
