US Patent 11319075 Compressible cushion for an aircraft seat

A compressible cushion may include a base structure and a plurality of foam layers positioned on a seat pan of the aircraft seat. The plurality of foam layers may include a first foam layer stacked on the base structure, and at least a second foam layer stacked on the first foam layer. A density of the at least a second foam layer may be less than a density of the first foam layer. The first foam layer and the at least a second foam layer may be cut at a length corresponding to a length of the seat pan when in an extended position. The first foam layer and the at least a second foam layer each may include a plurality of cuts, which may be configured to compress when the seat pan actuates between the extended position and a retracted position.
