We bought these to use at craft fairs; we wanted to be able to sit and still talk to people at eye-level. They're very easy to climb in-and-out of when someone does stop by. They are super lightweight (I usually carry them on my shoulder while carrying something else in my arms). They feel a little unsteady at first, but you get more trusting in their sturdiness - I have full confidence in them, especially after sitting in a mud puddle for 10 hours. These were the least expensive option when we bought them, and we are VERY happy with this purchase.
Downsides (and these are NOT deal breakers): the foot rest is about a 6 on scale of 10 for comfort (10 being highly comfortable.) The ends of all the pipes have black plastic covers which have popped off; on the bottom of the feet, we're probably going to use cane tips to replace them.
These chairs are probably in my top 5 must-have items for people who attend festivals or other events as a vendor.
