Massage Chair Recommendations

jaybird thought this was worth mentioning said

My wife and I have been long considering a massage chair for her. She’s had many back pain issues over the years and we’re finally seriously considering something for the house for her. Do you have a massage chair? Do you have any recommendations? She has been looking and says that she minimally wants a 3D but prefers a newer 4D chair. We don’t have a huge budget, and I know you get what you pay for. Do you have an inexpensive one under $1,500 you recommend? What about the next tier level? Just looking for some input here. Thanks.
