Cushioning for ergonomic seating

Abstract

Back and seat cushioning systems for ergonomic and adjustable seating are disclosed. The system includes a back cushion and a seat cushion, each configured for zoned comfort adjustment through the use of removable inserts, members, chambers, pouches, or cavities that allow independent control of firmness and support across different zones of the cushions. The back cushion can include one or more chambers or pouches configured to receive fill materials or inserts. The seat cushion can include a body with cavities or recesses configured to receive removable inserts or secondary cushioning members, or multiple foam layers of varying density to provide graduated support. Through selective placement or replacement of inserts or materials, a user or manufacturer can tailor the ergonomic performance, firmness, and contour of the seating system to accommodate individual preferences and applications.
