Patent ID: 7636971

Claim:
A foam dampening innerspring comprising: an innerspring formed by a plurality of springs connected together in an array wherein the springs are arranged in rows and columns, each spring having a body with a first end and a second end, the body of each spring being generally cylindrical and having a longitudinal axis and an outer diameter, the springs being spaced apart in the rows and columns and connected together in a spaced apart arrangement with each spring being spaced from each adjacent spring in the array; at least one foam dampening insert located in the innerspring in spaces between springs of the innerspring, the foam dampening insert having a central core which fits between the bodies of adjacent springs; a first segment which extends in a first direction from the central core and into an opening region of a first spring to at least partially intersect a longitudinal axis of the first spring; a second segment which extends in a second direction from the central core and into an opening region of a second spring which is adjacent to the first spring and to at least partially intersect a longitudinal axis of the second spring; a third segment which extends in the first direction from the central core and into an opening region of the first spring to at least partially intersect a longitudinal axis of the first spring; a fourth segment which extends in the second direction from the central core and into an opening region of the second spring to at least partially intersect a longitudinal axis of the second spring; and a fifth segment which extends in the first direction from the central core and into an opening region of the first spring to at least partially intersect a longitudinal axis of the first spring, wherein each segment of the at least one foam dampening insert is at a different elevation than every other segment of the at least one foam dampening insert.
