I've been using Wise Gusy seats lately. They have a bench with and adjustble back, flip forward base, dual 12v outlets, and an optional armrest.

As for the wood and foam comment a couple posts up, I like to drive my cars long distances, and I would highly recommend a steel frame seat, with springs under the foam. 2" of foam on a pieve of plywood is just like riding on the plywood after about 2 hours.
