i have rode in a 1966 Corvette stingray, a 1994 Corvette ZR1, and a 2003 Corvette Z06, had no issue with the seats, and im a big guy not ringing my own bell... but it all depends on the corvette you are riding, some of the early to mid 90s corvettes where not that comfortable, i find the newer ones quite cozy... seat comfort is a sacrifice they make for performance.

but if you prefer comfort thats your preference and i respect that fully.
