CURRENTLY SOLD OUT
Have have had lower back pain on and off for 25 years, when to relax your back to purchase a tweeter or exercise chair, you're lookiing to spend between 1000 and $3000. When I first used it it gave me some discomfort, but after the second week or so my back is never been better, I recommend it. I use it twice a day for five minutes at the lowest setting.
