[...]As it was going to be placed on newly laid carpet it was necessary to completely wash both sides with soap and water and put objects on top to flatten the plastic. This is NOT what was expected as we have ordered this item before and that item came flat in a box -- CLEAN and ready to lay down.
This product does not last. It soon cracks & sharp chunks of plastic break off. I buy it only because there are no other mats that are available for our rug and office chair setup.
It has really helped on the carpet. My chair rolls a lot easier. But when you set in the same spot you get a rut. I don't know what effect ths will have over time if any.
