ABSTRACT:
A seating suspension assembly provides efficiency in the manufacture of upholstered furniture such as chairs, sofas or the like. The preferred form of the invention comprises a pair of flexible, durable fabric straps having coil springs fixedly positioned therebetween. The fabric can be attached to a rigid wooden chair seat frame and the suspension assembly stapled or tacked thereto. The coil springs are thus suspended between the front and back of the frame. Upon upholstering, the suspension assembly provides a comfortable, crowned seat for the user. A method of forming the seating suspension assembly is also disclosed.
