Arresting means is provided to interlock each sleeve member with its associated leg at a predetermined location therealong. An adjustable bracing end support structure is adjustably securable between each adjustable sleeve member of each pair of legs to secure each leg of the pairs of legs at a desired inclined angle to each other and at a desired spacing therebetween. A tubular support member is secured to each of the adjustable sleeve members and extends transverse to the longitudinal axis of the sleeve member and the end bracing. An intermediate horizontal support member is telescopically securable between opposed tubular members of the opposed pairs of support legs to constitute adjustable elongated side supports.
