(under subclass 716) Innerspring-type core mattress in which at least one of the spring elements, providing support for a user of the pad, is a form different than the wire member of the helical strand-type material.
(1) Note. The incidental use of a noncoil spring (for example, interconnecting a plurality of coil springs), wherein the noncoil spring does not compress and provides support for a user, is not sufficient for classification in this subclass.
