These look nice, match our patio set, and function. However the are uncomfortable (hard and tilt you forward) so that if you sit on them for a long time or without a counter to lean forward against you back will hurt. and when you have the chair set to a middle height, then when you stand up the chair raises to the highest point, and when you sit down it sinks back down to where you had it locked. This makes you think the chair is broken and won’t hold your weight. You also have to lean back on them to raise them up or down, sitting down is not enough. So these are functional, but they leave a lot to be desired.
