A lot of people think that, there are a ton of FAA regs related to seats. Everything has to be tested in crashes. That also why it takes airlines so long to change seats to the new entertainment ones with power and everything. Your seat is your number one safety in the event of a crash. You are actually supposed to use the seat in front of you to brace yourself. It has a certain give to it so you don't run in to a brick wall when you land hard. If seats were easily configurable, every possible combination would need to be tested. Also whenever you do any work on a plane, you must have all of the supporting documentation, just think how long that would take to turn around. Document each bolt that was removed, when it was replaced, where it was..etc.. a lot of hassle.
