Need confortable chairs that pack up in a tube

We LOVE these Kijaro Chairs. DH has a bad back and he loves these for the support. They have locks so you can sling it over your back using the carrying strap if you need to. We also gifted a set to our son and daughter in law because he's 6'7" and 300 lbs (weight lifter) and she is close to 6' herself. With their height, they love the chairs and support too. We got the XXL size for him.
