what seat is it? I reused the foam on my back seat top and bottom, for the front bucket seats I had to get new foam because it was wore threw and I changed seat patterns. if you buy seat covers and foam from legendary chances are you wont have any fitment issues. I also don't recommend putting covers over covers, they will give you weird patterns from the original cover. if you take your time and pull the covers off carefully you should be able to reuse it
