I can put flooring (foam, plastic, plywood, extra carpet sheets) between my power rack and the plush carpet I have below it, but do you guys think my 400lb powertec power rack will cause permanent damage to the carpet (as in being squashed so much it'll never come back up)? I just put the carpet in and didn't know I was going to put something like this on it, and I may change the arrangements of the power rack in a few years, so I'd like to leave the carpet intact. Do you all have any experience with heavy objects on plush carpet floors? or suggestions? Thanks!
