Price - performance ratio - recommended.

I had an air cushion, which has come unfortunately lost by moving some time ago. That must surely everyone to find out for yourself, but I think it's great. To bulky The ideal alternative solution umflexiblen sitting balls. It pays through the cushion automatically much better on their own posture and for the price you get a high quality seat cushion included air pump, which facilitates finding of an optimum air pressure enormously. I contacted the seller, because I would have liked more detailed guidance on further possible exercises with the pillow and I have to say worth recommending! I have rarely seen such a nice customer service - prompt response to my request by mail - super fast delivery of detailed information material and at any time for the customer reach. Absolute top product and a great customer service, all at a really fair price.
