The stool is very quickly and easily installed by Plug procedures. The ball pump contained in Lieferumfnag makes a high quality impression and is still quite small and handy.
The appearance is quite well done, a fresh and bright blue, the approximately circumferential zipper would have more promised in black than in this bright creamy white, but I can live with.
The material used in the reference feels pleasantly, by the way when sitting. One has the feeling, this textile cover in Netzoptik is breathable, so a completely different feeling when sitting than when sitting ball. My partner, who approaches with completely different physical requirements to this product, it looks just the way.
What I find very positive: I I do not feel that I'm sitting on a ball. Also sitting hard not to so much as in a conventional seat ball that rolls away repeatedly. It may be that this is because I have the roles omitted, but one feels on the Sitness Half ball much safer and less shaky, but still has the feeling to move and do something for the back.
In addition, the fitness stool is still at an exercise poster, the one suggests a healthy back and a great figure. The idea with the removable Training for half ball is a practical matter and thanks to the robust zipper also quick and easy to implement into practice.
