A knockdown rack comprising three vertical posts having diverging legs at their lower ends for stably supporting the rack and a pair of supports fastened between the posts at vertically spaced locations for rigidly interconnecting the posts in a formation wherein the posts lie generally on a first circle with the posts spaced at about 120 degree intervals on the circle and the lower ends of said legs lie generally on a second circle larger in diameter than the first circle. Each support comprises a relatively flat horizontal member having three peripheral recesses therein for receiving the posts. Each recess has a mouth for insertion of a respective post inwardly through the mouth into the recess and a wall structure formed and configured for contact by the post at three separate locations on the circumference of the post. The wall structure has a height not substantially less than the diameter of a respective post for engagement with a substantial length of the post at spaced lines of contact. Each post is releasably fastened in a respective recess in each support member by a bolt.
