I like sports equipment such as this that are simple, while unlikely versatile and take very little space. Our physiotherapist recommended after an accident purchasing this cushion to strengthen the leg muscles of our daughter. She then showed her some exercises and since the cushion is here eager to use. Except my daughter and other family members have taken hold. It's just very pleasant, you can feel when standing on the pillow clear how many small muscles are repeatedly activated and also the sense of balance is promoted in a very pleasant and gentle way. I put my pillow, for example, like to go when I iron, I feel for your feet to be quite relaxing, although they are required minimal muscular all the time. On the website "BeBalanced" the manufacturer are also exercise videos and workout programs for free download, whereinthe exercise many ideas already of itself result, I find. The pillow itself is made of a solid, but this compliant foam, which was located on the feet and pleasant to the touch. It has no relation, the material of the cushion is but slippery and damp cloth. The material is according to the manufacturer robust, does not absorb water and is also equipped so that it has a protection against fungi and bacteria. Stain or Reinigungsbezin may not be used on the material! For us, this pillow was definitely a very good buy!
