Enjoying my gazebo, but it was a huge challenge to get the cover over the corner edges of the frame!  We tried everything we could think of from wetting the canvas and four of us pulling as hard as we could to stretch it,  to pulling on all four corners of the frame work to slightly "warp" it to get the canvas top to go over.... still couldn't do it.  Finally gave up and just have one corner where the canvas doesn't fit over it. Other than that,  it wasn't complicated to assemble.  It took four adults a little over 2 hrs.  One other annoying issue is when it rains, the water rolls down all sides and runs off like a waterfall splashing everything underneath so you only end up with about a 5 foot square area that remains dry ( on our 10 x 12' gazebo). Overall pleased with it anyway.
