I did not put bolsters in mine. I think it would put the seat height too high. I bought a brand new set from Wellcraft that came in the 1998 model scarabs. They are high backs. About a foot higher than what came in my 1996. Look a lot better and feel better too. I can understand your thinking though, especially if your boating in the ocean. On big water these boats are a little too short. I get out on Lake Michigan a couple times a year and if its not calm, I come home a couple inches shorter.
