2 Claims. (Cl. .5-e-262)
This invention relates to spring bed bottoms,
bed springs or the like and more particularly
to means for stabilizing the movement of a top
frame of a bed spring with reference to a bot5 tom frame which, through interposed springs,support the top frame. An important object
of the present invention is to provide novel and
advantageous stabilizing means of the general
character speci?ed.

One important feature of the present invention involves the use at a desired position along
