This chair is rather small and will not be good for someone who is taller than 5'7". The seat and back is rather small. 6 ways to sit is incorrect. There is 3 - no reclined, half reclined and full reclined. Otherwise, it does not stay still. The massage vibration is located in the middle space of the back only, if you are looking for lower back or shoulder relief, this chair will not satisfy you. For the price, I am happy (I paid 250$ + taxes) since it is made with very cheap material but if I had paid more, I would not be happy with this product.  I have a feeling that after one year, it will worn out. We shall see, I received it yesterday.
