Title: Butt muscle exercise not from this product
Review: prior issues of this product were made of what appeared as a soft rubber base that was supple and cushy. This one is made of a harder plastic composition and is reinforced by a hard back - these two qualities make it less fluid when you sit on it. The fluidity is what i had hoped to purchase.
