ABSTRACT:
A number of generally wedge shaped backrests and legless leisure chairs for sitting on the floor or on a bed, which orient the user's upper back at a higher angle than the user's lower back. These are ideally suited for people who want to be in a reclining type position, but yet want to do something like watch television. Most of the backrests/leisure chairs described also have a way of maintaining 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 backrest/leisure chair. All of the leisure chairs for sitting on the floor have a seat cushion (34) to prevent the user from slipping down out of place and most have a pillow (32) for a headrest. A number of ways of making a variety of types and styles of backrests/leisure chairs are disclosed including 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. Also disclosed are methods for providing lumbar supports in cushions suitable for these chairs and others. One method involves putting a hollow in the back of the main cushion (26) and filling it with a high firmness support member (28). Another method comprises piercing a previously manufactured cushion (86) with injecting needles (84) to inject a firming solution into the cushion (86) to provide the internal lumbar support (88).
