I liked the "alternative sitting" position, unfortunately whatever plastic was holding the vertical shaft in place turned into dust and now it bends so much it's impossible to sit at all.

Not as high as stated and when you sit on it a drops a few inches further. Wanted to return it, but once you put it together, there's no way to take it back apart (press fit connections wont come apart).

Delivered on time and the product is as advertised.

Not sure how much better they can get portable (within a space) great packaging very dynamic way to sit the real challenge is making the switch from standing or sitting to this. That and figuring a good height

Simple to put together. Easy to adjust. Works well. Getting used to the seat which is a bit different than sitting on a regular chair. No complaints. Appears to be good quality but only time will tell for sure.

Works as described

Works great. I shift between sitting on it and sitting on an exercise ball.

This seat eliminated my back problems, so I now have one in both my home and work offices. May not work for everyone, but it has been great for me. No problems mechanical problems with it so far at least.

I only gave it 3 stars because it didn't meet my expectations - this stool will not allow you to put your full weight on it - you kind of only lean against it instead of sitting it like a bar stool.

But it's too heavy and difficult to take apart for a return so I decided to just keep it.

I do occasionally use it when another person needs to discuss something with me for a long time, but not alone when I am working - my back hurts after 30 min or so

love it ... perfect for what I needed!
