A lumbar support uses a molded plastic shell and a series of adjustable straps to provide a support that can be easily fitted to a user's lower back profile. A thing cushion member, preferably a cushion sleeve, is supported on the straps and does not extend to the rear portion of the plastic shell, and preferably does not extend to the sides of the shell. Air circulation channels are defined between the thin cushion member and the rear of the molded plastic shell to assist in heat removal during use of the lumbar support. This lumbar support structure is also readily modified for increased durability that different applications demand.
