Outside of dents in 2 of the side poles it was very sturdy.  went together fairly easily as per instructions.  It is NOT 10'x10' except from the edge of the top outer top poles tip to tip, which are 6 inches further than the standing poles..  the base plates have about 3 inches on either side of them with the pole in the middle.  So the inside dimensions of the pavilion are about 9'x9', and this also coinsides with the area we covered which already had an 8x8' slab.  We thought we were going to have to add 2 ft to 2 sides to get it to fit.  nope.  wish it was bigger and that one of the sides went down for shade.
