Who used BackJoy?

Question

Workplace

I looked on foreign channels for a back / butt holder for the BackJoy chair. Has anyone used it? Helps? Or another marketing bullshit?

Answer 1

I recently created a topic about posture correction. BackJoy was not mentioned there, but I made two quotes for myself:

Not a single wrong posture cripples, it cripples a long stay in this position.

and

Use the horizontal bar / gym 3 times a week for 1 hour and sit as you like. Love yourself for real.

Answer 2

It helps, even a lot. The thing is irreplaceable. In principle, this is a very comfortable chair, but you can always have it with you. You can work on the floor, on the bed, on the cold ground...everywhere. Very comfortably!
