Seriously flawed
The purple back cushion is so small and so poorly designed that it is of little use. It is so thin that you have to sit so far back and firmly press your back against it to feel any support at all. That will also be difficult because there is only one set of straps (unlike much cheaper back cushions), so it doesn't stay where you want it to stay. I bought another cushion that had two sets of straps and you could remove the extra pieces to allow it to stay in place. If another set of adjustable straps were added and the cushion was at least double the thickness, you would have something good. It's not worth the price. I work at my desk for 12-15 hours a day, but I couldn't get past an hour with this back cushion. It's lacking. It's better than nothing, but then the price should be adjusted to suit it's functionality.
