Homedics Dual Shiatsu Massage cushion Model # MCS-370HA (Original Owner!). Massage cushion from homedics in great conditions works perfectly. This was a x -mas gift to a family member who is no longer interested in using it. Has couple of black marks on the seat corner but this does not affect the operation of the unit. Unit has a universal fit to just about any chair, has heat and kneading functions very light and easy to carry to anywhere that has an AC outlet. Massage can be described as very firm and deep tissue. can be uncomfortable at times due to the lack of padding between your back and the rollers. Overall it works very well. Please message me with your questions to avoid buyer remorse.
