This piece was designed soley for utility and not for visual beauty; it is an adjustable height platform for photographing small to medium sized items for internet retailing. The top opens to several fixed angles to support a backdrop, and the stacking platforms can be set-up in numerous configurations to allow optimal height for any given object. The base platform is strong enough to support an automotive engine block! The legs are hinged and "lock" into round mortises with the attached feet.
