US Patent 10426268 Furniture cushion

A furniture cushion comprises a matrix of pocketed springs, each spring of which is contained within a pocket of fabric. Foam at least partially surrounds the matrix and is secured to a cushion frame. The foam is bowed upwardly over the matrix of pocketed springs to create a crown. A webbing sheet underneath an opening in the cushion frame creates a cavity inside which the matrix of pocketed springs resides. The flexibility of the webbing sheet and crown of the foam create an active suspension system which provides support and comfort.
