The superior support found in the Donegal Firm's 825 Individually Wrapped Coils (in queen size) coupled with its gel and support foam upholstery layers will offer those looking for a "firm bed with firm support" a tremendous value for their bedding dollar. The foam-encased firm design provides more edge to edge sleeping surface and helps prevent excess edge compression that can occur after years of sitting on the side of your bed. The Donegal Firm is adjustable base friendly.
