ABSTRACT:
A hybrid mattress has a rail that includes a flexible foam member and a rigid supporting member. The rigid supporting member engages the lower outside of the foam to provide support and prevent bowing. A groove in the outer surface of the foam receives a flange on the inside of the rigid member, and the two mate closely so that mattress coverings can be clamped between the two.
