I'm on my second C&C seat with gel and haven't noticed any hardening of the gel or any unusual heat retention,,I did go with leather which seems to help aleviate the swamp ass that some people complain about, the vinyl factory seats hold ALOT more heat than the leather...just my personal observations and I wouldn't have spent the money to buy a second leather seat with gel if I'd experienced any issues in the first one.
