I mentioned the Solar chair last week (?)
It got its first outing this week, and I like it!
It is not as low as I was expecting and the extending legs are good. Get the back level, and to extend the legs, push the button and they automatically extend to full.
I've put full weight on it, on uneven ground, and the legs stay in place.
The added head rest cushion, attached by a locking strap is a nice touch, although I've taken it off.
