Worth it if you sit all day.
Great product. I sit at a desk all day and slouch so hard, and Iโve done it for so long, that my back has started to hurt. This product has helped me sit up straighter during the day. I started off with 15 minutes every day and now Iโm at 30 minutes every day, and I even sat straight up for two hours yesterday I sit on it what I think is upside down based on the logo, because I feel like it really forces me to sit up straighter then right side up.

Very Comfortable!
I wasnโt sure about this product when I ordered itโ it didnโt look comfortable. But itโs fantastic! Itโs very comfortable to sit in and better yet it feels great when you get out of the chair. I bought two of them so I can have one in my office and one on the couch to watch TV. The soreness in my hip is gone when I get up. Great product!

OVER MONTH LONG.... WAITING
I've been waiting over a month for it to arrive. TERRIBLE seller follow through. The product works when they deliver them.

Didn't quite hit the mark.
I thought this would be my answer to my back issues when at work. If it is on a flat hard surface and you can lean back in it, great, but if you put it in a chair it is hard to get the full support in the lumbar area. I work on a microscope hours a day and I have been searching for a chair or something to help with my back support. It has to lean forward with me. This didn't do the trick. I'll keep them as extra seats for home when I have kid company but it doesn't do the job I wanted.

Itโs perfect for my back support.
The material very solid and strong enough to support my back for long time. Not really comfortable itself but it not supposed to comfy right? For the good posture.
