I am so glad to write a review for this product. I could not find a similar chair anywhere after Brookstone quit making. My chair died after 4 years, probably from overuse. My wife and I retired and moved to a farm. I am lifting seed and feed bags constantly, heavy hogs that are trying to overrun my property (150lb) and bending over in our gardens and orchards which is a lot for a 69 year old. I finally found Johnson Wellness and buddy I am glad I did. They shipped me this Synca chair from their new Richmond, Va store. Everything about the chair I love. The packaging number one was superior. It was so easy to unpack and plug in. The performance was much better than I expected, from heat, to my sore hips and lower back and comfort. We like this chair because we dont feel trapped in....if we have to get up, it is easy and also it is so comfortable I use it to read books etc...
I lifted weights all through life and have injured myself numerous times, so Im susceptible to strain. I , knock on wood, feel like I can do anything as long as I can get into my chair at the end of the day, I will be fine. I only wish I could take it on vacations etc....it is the main thing I miss when I go away. If you think circulation and blood flow are important to maintaining a healthy back, then think no more and buy this chair. I can't recommend it high enough and it is relatively inexpensive.
