Talk about the ultimate chair!! The Walkstool is a great product and if you're like me who carries a ton of gear around for astronomy from the house to the car and off to the observing site, it is portable enough to do the job. I was able to fit this thing in my back jean pocket legs first, while carrying my gear out to the car. Obviously making it nice for the return home and unloading on those cold nights. It is extremely light it weighs less than my 35mm Stratus eyepiece and durable enough that I lay my telescope in its case including my accessories case on top of it when setting my CG5 mount and counter weights on to the tripod. It has a built in strap for belt or clip use and not to mention it can be disassembled into its components if needed for parts replacement.
During my observing session through the telescope a flip of the mirror diagonal, and wala upright seated position. When doing a walk around all the telescopes at our site it sure is nice to pick up my chair as if it were a pillow taking it with me for the comfort. There is nothing like durability and portability. On a scale of 1-10 it's a 10. Two thumbs up.
