Abstract
Abstract A portable seat provides improved comfort and includes a single, pair, or multiple numbers of moving seating assemblies. A motion mechanism provides each seating assembly with at least one of total rocking, vertical, lateral, and turning movement and in one embodiment generally constrains the seat members of the seat assemblies from interference with each other. The seating assemblies are provided at a neutral angle that corresponds to the particular application of the seat. The amount of rocking movement and/or vertical movement is based on the neutral angle. In concert, the neutral angle orientation, rocking movement, and vertical movement cause the weight supported by an occupant's seat bones, posterior, and thighs to be optimally distributed on the seating assembly, improving seating comfort as applied to a given seating environment.
