I got the 6x6 size. It popped open and up right away when I removed the belt that held it all together. Maybe I should have read the instructions beforehand!
I haven't folded it back up yet. That will not come until fall. I set it up on my concrete patio because I wanted it protected from the rain. It is very light, though, and can be easily moved to a location in the yard.
The patio has a cover and is protected from the wind on two sides, so I have not secured the screen house. So far it has stayed in place and we did have some high winds one night. The screen is very good quality and I would say the tent is big enough for 4 chairs.
