Abstract

A boxspring is provided with stop members for limiting the amount the springs therein can be compressed. The stop members may be light weight hollow cylindrical members fitted within or about a selected number of springs. Supporting braces having a height sufficient to prevent overstressing of the springs when compressed may also be employed. The braces also have the advantage of providing additional stiffness to the boxspring frame. Areas of the boxspring most vulnerable to damage are protected by selective positioning of the stop members.
