2 months after we bought it, one of the straps failed suddenly with my wife and child on it.  They both crashed to the ground and got hurt.  They are way, way below the max weight capacity.  The straps are clearly not rated to be in any amount of sun.  Ours was kept under a shade but you can see the straps had lost all strength and are now sun bleached...after 2 months.   During my phone call with Wayfair I was told they would be pulling this product from their site and giving us a refund...neither has happened.  Where is the negative star button??
