Abstract: A vertically supported shelf surface having adjustable lower braces which may be adjusted horizontally to engage upright supports having different diameters, such as trees. Each brace has several openings to engage rails which slide there through. Two spaced vertical supports with holes are fixed to the braces and have holes through which a belt extending through them may be fastened around the upright support (e.g., a tree). The shelf's planar surface may be downwardly inclined towards the upright support tree and have a peripheral edge rim. Two functionally similar but with different designs may be used for the vertical section's braces.
