Most of the chairs described also support the lumbar region of the user's back in a relatively natural lordotic curve, some through a lumbar support member (28), and others through making a convex contour on the lower portion of the chair. The chairs have a seat cushion (34) to prevent the user from slipping down out of place and most have a pillow (32) for a headrest. Also are adjustable metal frames and wood frames, dual position chairs, chairs using a firm support foundation (42 and 46), chairs having armrests (36), and outdoor type styles. One method comprises piercing a previously manufactured cushion (86) with injecting needles (4) to inject a firming solution into the cushion (86) to provide the internal lumbar support (88).
