After purchasing ... we almost returned it - but, for some reason we decided to keep it and have it professionally installed. The roof in-between each of the post holds and pools water !! The fabric is now tearing where it was poorly sewn together. I would love to do something about this - but, the company does not offer replacement tops --- and we have it in concrete to make it more sturdy and stable ! Looks like we are out of luck with a very lightweight - water holding - MESS !!!
