This is the best gazebo I have ever had. It is very sturdy and solid in structure.
When we put this up, it took two of us (both women). The first thing you have to do is grab two legs each and pull outwards. When it is closed, it is like a concertina fashion and pulling it out opens up the roof part which snaps into place. AT this point, the legs are not fully up and it's a good job because otherwise, we would not have been able to throw the cover over it.
Unroll the cover and open it out flat then pull it over the roof of the frame. The corners are then velcroed on from the inside (you have to crouch down under the frame to do this)
Once the cover is in position, you can simply slide the legs upwards to make it taller. There are three heights. We always have it on the middle of the three. The legs slide upwards and then little spring loaded buttons come out through the holes in the legs to keep the legs up.
It took me and my friend about fifteen minutes to get it up and be sitting in a deckchair underneath it.
We did add weights to the bottom of the legs to make sure that there was no chance of it blowing away if a gust of wind came. However, if you don't want to use weights there are guy ropes that you can peg into the ground.
