Very light weight and thin metal, thinner than I expected for a gazebo labeled "all seasons"  Received in good shape, but due to material thinness, several support posts had dents in them upon unpacking.  Also, the top corners of the roof where the canopy attaches via Velcro just pulls up.  The Velcro is riveted on top of the frame, but not at the corners... Wayfair did a great job in rectifying these issues immediately.  5 stars for Wayfair..3 stars for the product.
