I was impressed with the sturdiness of the exercise ball. I had known the Weider name for years and was sure I was getting a quality product. I would recommend, and have purchased one, to family members.
I bought this size ball because it is the one recommended for my height (I am 5Ft1) it is tiny, even fully inflated it isn't as big as my other stability ball which is also 55 cm.
They melted my plastic chairs!!!! What are they made of? They were resting on a blue chair. The paint from the chair melted and ruined my floor and everything else it touch
This ball was a little smaller than I expected but it is useful nonetheless. I actually thing the smaller size works for me since I have a short stature.
Very happy with this ball.
