Material is not beefy enough so the chair sinks in and then you have to stand up to move the chair. Material should be harder plastic. or I guess I could be lighter. Sorry now that I bought it. But it's too late. I own it.
Size and appearance of the mat are fine however the mat developed a series of cracks after only 6 weeks of daily usage by an average weight (150lb) male in a standard wheeled office chair. Way too flimsy to recommend purchase of this item.
This is a great product and does stay on the thin office carpet I have it on. That's not the problem in fact that's a good thing. However my darn office chair wheels continue to slip easily off of the mat which makes me crazy. Because I just had my left hip replaced and when I go to sit down I have to make sure that I'm holding onto the arms of the chair very tightly or the chair will leave me and I'd fall down. Life gets crazier and crazier for me. :)
