The mat works well as expected. The thickness was important to us as it will last longer than a previous mat. All in all I am very happy with this purchase.
this needs to be firmer stiff. i use it on carpet and it makes pits in the plastic so its hard to get the rollers out of the pits . it doesnt matter what u weigh. my granddaughter who is 70 lbs even made the chair sink into the flimsy plastic. sorry i bought this. husband will cut a sheet of plywood and attach it to the top. this is a piece of junk.
