How necessary are these for a home gym? I recently just purchased horse stall mats. I am not able to put plywood under or double up since I am in a low basement. I am literally at the maximum height I can be at. I have only dropped the weights hard once on power cleans, but as I am getting into heavier deadlifts and cleans, I feel I will end up dropping more often. The horse stall mat seemed to work great so far, but I fear heavier weight and continued wear and tear will break down the concrete underneath. The main reason I am asking is because I can't find any bumper plates around here at all. I would have to travel about 2 hours out of town to get them. As we all know, shipping is a bitch as well as gas at the moment. I need to get more weights anyhow, so in your opinion is it worth the drive or should I just pick up more regular plates?
