No more sciatic nerve pain I ordered this because I have been making frequent 2-hour road trips to care for my aging parent and I was suffering from sciatic nerve pain. I'm happy to report that after the last two road trips, I did not have sciatic pain. It appears that the BackJoy device really helped to correct my sitting position and thus prevent the usual stress on my sciatic nerve. When I'm not traveling, I use it when I sit at my computer desk for long periods. I'm very pleased with this purchase.

Doesn't perform as advertised Used it for 2-3 weeks and it helps just a bit. Never like shown in promotional videos, which are really exaggerated. It may be improved by giving it some height in the back or more slanted, and using a more sturdy material. Not pleased and would not recommend. Too expensive for something that doesn't perform as advertised.

EFFECTIVE RELIEF WHILE SITTING I purchased my”tractor seat” several years ago. MRIs showed L4-S1 stenosis and various disc issues. Using this seat has given relief while sitting in the car. It is very much worth having.

Excellent Support I have been using the BackJoy seat for years, primarily in my car. I recently bought another plastic material seat because I feel like it provides better support than the softer seat, which I also use. The harder seat works better in the car, especially over rougher roads. I'm very satisfied with BackJoy and my brother recently used my two different seats and was very pleased with the support. He preferred the harder seat.

Great Posture! This SitSmart Posture Plus keeps my back in the correct posture when sitting on chairs and bleachers! It really does for me everything as advertised: "safe and effective way to relieve lower back pain and improve posture." Was concerned that it would be hot during the summer months. Not so. Thank you BackJoy!
