I love this gazebo but had a very sad experience with it this weekend. We have had it for six months now. The columns that support the gazebo are hollow. My cat and I heard noise and determined that a bird had made its way through the top of the column but could not get out. My husband was able to unscrew the gazebo from our deck and lifted up the column to free it from the bottom . Unfortunately there were two other dead birds in the bottom of the column. We did not assemble this gazebo so don’t know if there were caps that were supposed to close off the top of the column that went unused. 
We plan to cover the tops of the open columns with something to avoid any other critter deaths.
