Patent attributes
Hybrid coil and air chamber assemblies for cushioning supports generally include pressurized air chambers that are positioned intermediate strings of pocketed coils. In this manner, the coils and air chambers can move independently but can be made to cooperate to provide firmness control, contouring and/or support of a user thereof. Air pressure within the air chambers can be independently adjusted to manipulate firmness and/or contour properties in specific zones defined by the presence and location of the air chambers, e.g., pressure of the air chambers corresponding to the lumbar region can be adjusted to eliminate high pressure points. Still further, the pressure within the air chambers can be automatically adjusted to different applied loads as a function of movement. Also disclose are processes for adjusting a mattress including the hybrid coil and air assemblies.
