Purchased this last summer and it basically useless. I suppose anything short of bolting this to the ground, will not keep this thing from tipping over. First, I used three 12"x24" pavers on each side of the base. Opened it up, and with the slightest breeze, over it went. Then I grabbed my 30 lb dumbbells, and placed them over 2 of the crossbars. Same result. If the dumbbells were not able to keep this from tipping over, I'm not sure the weighted anchors made for this would be able to. And asides from the tipping issue, the fabric has completely faded. Its almost beige at this point. It hasn't been a year yet. You get what you pay for. Would not recommend this at all.
