The present invention relates to a collapsible seat base. When operatively interconnected, and in its raised resting position, the device forms what is substantially a forward leaning parallelogram bisected by the consolidated length of a slide and slide-guide, which forms two substantially congruent triangles sharing a common side. In its lowered resting position, the device collapses to form an elongated rectangle bisected by the fully extended slide and slide-guide and rests substantially atop its support surface at a height defined by the cumulative thickness of each component. Generally the support mechanism comprises: a base and support member, a first and second side member, a slide and a slide-guide.
