I took advantage of the black friday sale of this chair. The waiting of delivery took longer because of the sales volume. But it’s all worth it once I got the chair. I like the fact that it came fully assembled, all you have to do is plug it in. I can’t review yet about its durability because I just had it for 2 weeks, I hope they stand by their warranty. But as far as performance, it works great as expected, it actually loosen up some of my tight spots and notice less back pains. I’ve been bragging about it to my coworkers how it helped me a lot.
