Seat for molded plastic chairs

摘要

A seat on a stool, chair or bench has a permanent depression in the surface of the seat that corresponds in shape to an end view of a human iliac bone. This shape has concave curved central channel which has a first end and a second end. There is a first concave boomerang shaped channel having a central portion connected to the first end of the concave curved central channel and a second concave boomerang shaped channel having a central portion connected to the second end of the concave curved central channel. A chair, stool or bench whose seat has such a permanent depression is more comfortable to the person sitting on that seat than hard seats on seating devices known in the art.
