The mat is rugged but it slides on my hard wood floor. It could use some rubber strips on the bottom to keep it in place when I am rolling around on my chair and especially when I roll off the mat and try to get back on to it.
Excellant mat for my office chair. I have ceramic tile and with this mat my chair rolls very smoothly from computer desk to office desk. It stays in place on the floor and does not side around. I do not feel the grout lines between the tile squares.
Needed a cair mat to use in area with new laminate floor.. color is good contrast with floor and protects the laminate..chair rolls easily and mat stays in place..
