We have a 12' x 12' platform off the side of my yard that stretches into the lawn. This gazebo has side covers that when zipped, keep the furniture dry from the sprinklers; unbelievable! When we walk into it in the morning, it's dry (no morning dew/wetness either)!

Pros: Relatively easy assembly (2 guys, 2 1/2 hours, 4 beers); the four substantial posts come ready to be screwed directly into a deck.
Cons: Screws for anchoring to deck not included, but should be!
