This is merely a piece of cloth stretched between the frame borders, but it works perfectly. It arrived quickly, all parts present and in good condition. I didn't put the castors on, as it will be more or less always in one position. I simply attached some felt sliders on the bottom to prevent scratching the floor and to allow clearance for the center screw (which is not flush fit). Overall, a reasonable deal for the price point.
