Floor mat is fine and I hope it lasts longer than the previous one. Mat was delivered filthy with no wrapping. Footprints were on smooth side indicating delivery person had walked on it with dirty shoes. Studs on other side were full of white pieces of something (paper cardboard fabric?). Had to spend a half hour cleaning and washing the mat before we could use it.
This mat is way too thin and shows marks from the chair wheels. I had to place it under a heavy rug for 3 days to get the mat to lie flat after unpacking!
