Like A Rock
The product was as advertised, however, it is VERY hard and uncomfortable to sit in. I purchased this to keep in my office chair to use when I began getting stiff from sitting all day. The seat of this chair is like sitting on solid wood. It does vibrate very well, but it is also noisy. The back of the chair is also very stiff. The rollers do a great job of reaching the entire back, but you have to move forwards and backwards in order for the rollers to be comfortable and not create pressure points that are painful. The neck massager sits uncomfortably farther back than the other, which means you have to lean back quite far in order to feel the full effect. The fact that you can use each feature independently and create zones for the back massager is a plus. But the overall discomfort in sitting on the massager compels me to return the product.
