The Disadvantages:
Either the fabric of the chair is too loose, or the struts under the seat have been poorly applied, because press both the Po and thigh struts while sitting very strong. That it sticking out, you can see even at first glance. Without a cushion to sit comfortably on this chair is therefore not possible. And that's probably not the point of a relaxation chair. Also lying in the prone position is a bit uncomfortable because the leg support is not just enough when you lean back and remain bent legs, therefore, although it is already very far back hunched with his back.
Here already first scratches were also out of the box in the aluminum surface.
Conclusion:
Unfortunately, the chair fails just when important criterion - the seating comfort. With a foam pad it sits really comfortably without but unfortunately not.
