The delivery was a bit slow on this but with CoVid19 backlogs with everyone setting up home offices, it’s to be expected. My husbands chair now rolls easily on the carpet. It’s large enough to be practical and effective at saving the carpet and making the movement easy, but it’s not so big that it covers the rug so much the dog doesn’t want to nap there while my husband works. Also clear enough so it allows the carpet to show well.
