Bought this mat to better support an office chair versus having directly carpet.  The mat itself seems adequate, however, given the fact it is new, it is unclear how long it will last.  The shipping experience with this campany/Wayfair was awful.  The item was delivered well past the estimated date.  Fedex delivered the mat to the wrong house on the same street, denied that an error took place and never follow up after committing to do so.
