发明名称 Chair support stretcher
摘要 A chair includes a seat connected to legs of the type having tenons that extend upwardly through the seat and are flush on their top surfaces with adjacent areas of the seat. To prevent the legs from being driven upwardly through the seat due to excessive wear or forces, support stretchers are connected between pairs of the legs and the underside of the seat. Additionally, the stretchers provide mutual, lateral support between the front and rear legs and provide horizontal support to the seat for greater weight bearing ability.
