Abstract
A mattress assembly may include a foam frame, an inner assembly within the foam frame, the inner assembly including a foam core and a pocketed coil assembly. The pocketed coil assembly can include a plurality of individual pocketed coil springs having a height. Each coil spring may be joined together to a neighboring coil spring such that at least a majority of the height of each coil spring is configured to vertically deflect without deflecting the joined neighboring coil spring.
Claims20
A mattress assembly, comprising:
- a foam frame;
- an inner assembly within the foam frame, the inner assembly including a foam core and a pocketed coil assembly;
- wherein the pocketed coil assembly includes a plurality of individual pocketed coil springs having a height, each coil spring joined together to a neighboring coil spring such that at least a majority of the height of each coil spring is vertically deflectable without deflecting the joined neighboring coil spring.
A method of making a mattress, comprising:
- providing a foam frame, a plurality of pocketed coil springs, and a foam core;
- assembling a coil assembly by:
- joining two or more coil springs of the plurality of pocketed coil springs to a spring assembly frame;
- joining a coil spring from the plurality of pocketed coil springs to a neighboring coil spring of the plurality of pocketed coil springs such that at least a majority of the height of the coil spring is vertically deflectable without deflecting the joined neighboring coil spring;
- placing the coil assembly within the foam frame;
- and
- placing a foam core within the foam frame, the foam frame being above the coil assembly.
A pocketed coil assembly for a mattress, comprising:
- a fabric sleeve;
- a plurality of coil springs spaced apart at regular intervals within the fabric sleeve, the plurality of coil springs being joined to neighboring coil springs of the plurality of coil springs only at a bottom portion of each coil spring of the plurality of coil springs thereby allowing each coil spring to vertically deflect without deflecting another of the plurality of coil springs;
- a rigid frame about a perimeter of the plurality of coil springs only joined to the bottom portion of at least several of the plurality of coil springs.
