I recently purchased the Staples Hard Floor Mat 46x60. It came quickly rolled loosely and only took a day or so to lay flat. It works beautifully under my desk and chair. Thus far I would strongly recommend this product due to price quality and service.
not pleased at all in fact very poor quality---terrible. the mat is not hard enough and gets dimples in it from the rollers on my chair. in fact when seated in the same position for awhile it's difficult to move back or forward on the the chair because of the dimples. the material should be harder/stiffer. the previous mat I had was also bought at staples some years ago and was of much better quality i.e. stiffer and harder and it did not get dimples like this one. you need to do something about this---and this is the best one you have??
It was easy to lay down relatively speaking. After all it does have plastic spikes on the bottom. It laid flat immediately without any problem. I wish it had been as easy to remove my old one as it was to lay down this one. It was easy to roll my chair onto the mat & it smoothly rolls around on it. I'm glad I made the investment & sorry I waited so long to replace my old one that had been falling apart for weeks.
