[...] Much too thin. So chair remains in "holes" under rollers and does not easily roll on surface. Die-cut is lopsided. i.e. the first spike row on underneath is skewed and does not go completely from left to right side.
Much better price buying this mat online and having it shipped to the store for free where I picked it up. Looks and works great and you can see the beautiful hardwood floor too. Can't beat the online price. Great deal.
