This gazebo was very easy to assemble with the exception of stretching the canopy over the top beams, it seems to be about an inch too short.  In addition, the large canopy arrived with a rip in the corner that made it impossible to attach to the support beams anyway.  I contacted this manufacturer for a replacement and they refused to help - I contacted Wayfair and they immediately issued a full refund because the product is sold out.  I'm not overly impressed with this manufacturer but I'll definitely shop with Wayfair again.
