Making classes comfortable Backjoy seats make all day classes comfortable regardless of the quality of the chair seats. This is a great advantage for needleworkers. They also greatly improve long plane rides.

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.

misleading advertising I am sure this product has helped many people sit in office chairs, but... Misleading advertising. The pictures are confusing, and show people in twisted yoga poses. And they show a backjoy sitting in the seat of a car with no person. After purchasing one, I found through customer service that although the website says "Can be used in any chair", they are NOT meant to be used in a car or in any seat where your back is against the back of the seat, such as a sofa or recliner. Since I only wanted it for my car, this was worthless.

2 weeks delivery time to Canada 2 weeks delivery time to Canada. Product purchased to improve my seated spine alignment and there is definitely a noticeable change for the better in how my lumbar and thoracic spine align in my high quality office chair.
