ABSTRACT:
A furniture seat base which employs a series of front and/or back torsioned sinuous spring bands. Predetermined patterns of torsioned bands produce an interaction which generate spring dynamics designed to produce a seat unit which may be sat upon from the front, back, sides, or corners with excellent comfort characteristics. The bands are selectively supported adjacent the rails to obviate objectionable "lean-out."
