I loved this stool. I had not yet had the opportunity to use it on a hiking trail or museum. I used it a bit inside my home. On the occasion when I leaned to one side, the stool collapsed and a nut/bolt/something came out of its hole/socket/whatever - I fell onto the floor. I went thru the process of photographing the stool, sending an image of my receipt, and submitting my warranty claim. I heard nothing for about 2 weeks. I called and was by a woman that it would be addressed. After another couple of weeks with no response, I called again. I was again told that it would be addressed. I received no reply. So beware. It would be a wonderful stool if it hadn't come apart. And by the way, I'm 5'10" and weigh 160 pounds - so weight shouldn't have been an issue. No customer service for me.
I use this stool primarily when hunting and sometimes camping. When hunting I encounter uneven and soft ground that seems to put stress on this frame. The end caps on the telescoping frame worked loose and the legs pulled off numerous times when extending the legs which is frustrating when trying to set up and focus on the hunt instead of fixing gear. And finally while perched on a hillside and one of the legs snapped when I leaned to one side! I am just under 200lbs and thought for the price and performance that this would be able to withstand the abuse. Very disappointed.
As a guide, I like having a place to sit thats better than a sit-pad and definitely "better than a rock". I don't usually want to carry the extra weight or use the space for a full chair though.
At 14.5 oz (on the home scale), I regularly add the BTR stool to my gear, and i've never regretted it. It's lighter than (and folds down much smaller than) my helinox zero, at about 40% of the cost. I'm 215 Lbs, and I found the stool to be very durable, until finally it was time to get another one. It was used regularly by myself and clients, who always enjoyed it. It also stays on squishy surfaces (like sand or boggy ground) better than most of my chairs. While it doesn't have a backrest, i've sat on it for long stretches comfortably. It initially looked too light to be comfortable or durable, but I've been pleasantly surprised. When folded, it packs conveniently without any flapping fabric or parts that catch on other gear. While I generally like a backrest, I've been very impressed with this little stool.
AWESOME. light, sturdy, capable. Already ordered two more and recommended to a friend!
Awesome product - lightweight and comfortable for backpacking
