Abstract
This disclosure addresses mattresses. The mattress includes a core made up of multiple zones. Each of the zones includes a plurality of core elements, the core elements being formed from at least one wire coil spring at least partially contained in a fabric pouch. The core elements are typically joined in linear chains. The zones vary in support firmness according to the selection of a user. The core elements include wire coil springs formed from wires of at least two different sizes, and of at least two different heights.
Claims3
A mattress device, comprising:
- a core comprising a plurality of zones, each of the plurality of zones comprising a plurality of core elements, each of the plurality of core elements comprising at least one wire coil spring at least partially contained in a fabric pouch, a pair of side zones are formed from multiple rows of pencil wire coil springs, a pair of end zones are formed with alternating pencil and larger wire coil springs, a head support zone and a foot support zone are formed with wire coil springs comprising light wire, and a trunk support zone formed from wire coil springs heavier than those of the head support zone and foot support zone;
- wherein the pencil wire coil springs have a smaller diameter than the larger wire coil springs and are longer than the larger wire coil springs;
- a mattress cover to enclose and secure the core;
- wherein a first core element of the plurality of core elements extends above a surface of a second core element of the plurality of core elements within a same zone of the plurality of zones of the mattress device, and wherein at least two of the plurality of zones vary in support firmness from one another, according to a selection of a user.
