A structure for an easy chair, sofa, or the like, which affords improved comfort and a simple construction, comprises a plurality of deformable sealed blisters (13,14) containing a fluid having a set boiling temperature, such as a Freon, and electric resistance heaters (18,19) associated with said blisters (13,14) to vary the fluid temperature and, hence, the blister volumes and pressures. |
