The reason I ask is because the 1 piece seats usually have high side bolsters, higher than adjustable seats. In addition to the harness setup you will find that getting in and out of the car is going to be a major pain in the ass. The 1 piece buckets are typically lighter than the adjustable ones and as long as you're not into the 'ghetto-lean' way of sitting you'll find that a quality 1 piece bucket is pretty comfortable. This only applies to the fiberglass, carbon or similarly formed seats. Once you get into the tube framed seats then all bets are off on comfort.
