I am writing this review while sitting on my 60cm height walkstool. The seat is very small, and as another comment mentioned, it can be unaccommodating to the male anatomy. I have to manually reposition my balls each time I sit down or there is no space for them and they get squashed uncomfortably by the support between my legs. Because it is a tripod, you either have to sit with one corner between your legs, and one behind each butt cheek, (digging into each cheek may be more accurate), or try to sit with one of the supports behind you, and one on either side(I find this impossible myself, as I have to lift my legs off the ground and I sink back into the stool). That being said, if I work at it, I can get into a fairly comfortable position, and the tall height allows you to have part of your weight carried by your legs on the ground. I am a 6 foot (5'11") tall male, who weighs 190lbs, with a 34" waist. After 15 minutes or so, it can get uncomfortable, and you have to be very conscious of how the seat is supporting your weight. That being said, I'll probably keep it and use it. At the low height setting I don't have these same issues, as it puts me in a nice squat position, and I can squat on basically anything. At the low height it works like a monopod with just one point of contact with the ground. It's about as comfortable as when I sit on my skateboard, except you have a rotational axis of movement instead of a horizontal one. I actually have figured out how to sit on the full height configuration with one support behind, basically on my tailbone, and the two front supports supporting each leg midway on my hamstrings. I also have to lift my feet off the ground, and grab onto the midpoint of the supports with my feet like a monkey, halfway between the seat and the ground where the supports intersect, with my feet. This is probably the most long term comfortable position, just as long as you get your pelvic tilt right, so your lower back doesn't curve. So with a little work, it can be pretty comfortable. I got the basic model and not the comfort one, so that's what you might have to deal with. Other than that, the quality seems excellent, and I anticipate it will last a long time and go anywhere without trouble.
