rest of the seats are in good condition. It is a '98 Infinity l 30
sort of a tan color- thanks

Buy seat covers.

u might want to take this one by an auto trim shop,its possible they could remove the seat & take the bottom off & repair it for reasonable amount,that is really the best way to do this,anything else u try & do will be very noticeable,i seen one the other day with duct tape on it,then they had a cover over this because of the sticky residue from the tape,id check in to getting it repaired,it may not cost over 100 bucks to get it redone the right way,and the car probably is worth fixing it in,good luck with it.
