USE AT MY SEWING MACHINE ON A LOW PILE RUG; SIT ON A ROLLING OFFICE CHAIR; THIS ITEM COULD BE A LITTLE THICKER. I CAN SEE WHERE THERE WILL BE DIPS IN IT WHERE I NORMALLY SIT AND BE HARD TO ROLL OUT OF THEM. TIME WILL TELL. FOR THE PRICE I PAID IT WILL DO. I THINK I NEEDED TWICE THE THICKNESS BUT YOUR PRICE WAS TOO HIGH FOR ME FOR THE ONE I REALLY WANTED.
Returned product--not as advertised. the product numbers matched but ours had the bumps on underside which would scratch flooring--flimsy and rolled up--was expecteding a smooth hard floor protector
