I purchased this item a couple of weeks before needing it. I stored it in the garage and the rolled matting flattened into itself. It has been 3 weeks and it still hasn't flattened properly on the floor. I am using it on laminate so it does slide a little but that is to be expected.
When we seen what our office chairs did to the old office flooring I ask that these chair matts be used so all we need to replace over time are the chair matts not a whole new floor. Which never happens in the old office.
