I tried several chairs, this one is the most stable. The color choice of the provider is not that great, but the metal structure is quite massive (and heavy!), The fabric is good to sit on. It also expresses nowhere a rod on the back or something. The thing is most closely approximates what the chairs, as they are known by hotel pools. The sun keeps out rain and also the daily water sprinkler in the garden and you can just leave. I have a second bought later.
A small drawback, however: the screws must on the tilt axis to follow every couple of weeks, which dissolve (probably through the back and rolling heavily the children) over time.
