A planar assembly support includes a pillar and bed fixable on a surface. A bed center hole is provided with an inner screw thread. An inner locking member has a protruded retaining ring and an outer screw thread on a lower portion outer peripheral face, and fixedly locks on the bed via a threaded connection with the inner screw thread of the bed. The outer screw thread may consist of at least two sections of a convex spiral constituting less than a complete revolution. The pillar and inner locking member can be dismantled together from the bed. The bed left on the surface occupies a smaller space and, therefore, reduces the risk of tripping, while providing convenient mounting and dismantling without damage to the surface. A lock/release mechanism may be provided to prevent inadvertent rotation of the pillar in an unscrewing direction with respect to the bed.
