ABSTRACT:
A crowned mattress having an inner spring unit with a plurality of spring members, a foam layer, and a cover. Peripheral edges of the inner spring unit are compressed together by compression members to provide a crowning or bowing of the inner spring unit that is translated into a crowning of the mattress. The foam layer can also be crowned to provide additional crowning. Spring members within inner spring unit can be reinforced by resilient members to increase an effective spring rate of a reinforced spring member. Reinforced spring members are dispersed throughout the inner spring unit in a desired pattern.
