Hello There, the floor mat was delivered well packed. The material is high quality, so after unpacking passes little time until the floor mat can return to its original shape. One side is smooth, this is one down. The other side is a bit rougher, it then rolls the chair. For me, the floor mat lies on a parquet. It must be held no slipping. I would buy the protective floor mat definitely be back. The size is sufficient for me. Thanks for the smooth running. Mfg Thorsten
