The only thing that disappointed me about Corbin was their refusal to install a PMS pain reliever (butt warmer). They said "we only install that on the seats with special frames", I said, "I don't care if you install a switch or not, just leave the wires sticking out and I'll take care of the rest". They still wouldn't do it. A-holes. It's just a **** pad, glue it to the foam and cover it.
