Bed Bottom Spring. (open access)

Bed Bottom Spring.

Patent for new and improved bed springs. Due to this design's construction, "in addition to the support furnished by the top spirals, the platform furnishes a broad level bearing for the mattress and prevents sagging between the springs or injury to the mattress itself. Also, the parallels, being springs in themselves, additional comfort and elasticity are added to the bed, and the springs themselves are more readily adapted to the varying width of the slats of different beds" (lines 25-34).
