I normally opt for the most expensive product in a given category with the assumption that it is made from different materials and ultimately will have better quality. When shopping for this chair, I found a much more expensive brand, nearly three times the [rice of this, that I considered. I could not help but think it was way over-priced for what it was. I decided to step down a bit in price and I am so grateful that I did.The chair was extremely well packaged and each part was labeled, making it easy to assemble. The only complaint I would have is that it was somewhat unclear which direction the cross supports should be facing and the diagram was wrong. That said, it's pretty obvious when you look at the cross pieces that they are longer toward the kneeling end than the seat end. For that to work, the cross members are angled slightly. By looking at them, or holding them upright on a flat surface, you can see that they lean one direction or the other (depending upon which way you have it facing. Obviously, given what I mentioned earlier about the kneeling pad end being further apart than the seat end, the angle should point downward toward the seat to make that happen.In the manual that came with it and in other things I have read or seen online, they suggest starting out in shorter periods of time,m then working up to a full day. They also mention to shift your position from time to time. I had no problem using it the entire day immediately. I do shift my position often, but generally find this to be as comfortable as a seating chair.As as bonus, I have learned that I can use the natural curves of the chair to stretch my Achilles while sitting on it. I have plantar fasciitis, which as a runner is quite painful and hard to get rid of. I have found that I can gently stretch my achiles, one of the main exercises for controlling the pain.Used properly, you can really focus on your core and exercise your abs while working. If you happen to be ADHD, like me, this chair may help you to focus.With regards to quality, I suppose time will tell. The padding is thicker than some of the competitors, but I do not necessarily think that is better. At the end of the day, it will become about how long it lasts and how the material it's made from compresses.All in all, I highly recommend this chair over the more expensive Balens product. The Balens product does offer an interesting option to add a back rest, but I feel like that is unnecessary and contrary to the intention of a kneeling chair as it takes you out of your core when you push your lower back toward the support, which is the natural tendency. You would have to be pretty disciplined to not do that. As long as this product holds up fairly well, I will never know if it's equal in quality to the Balens product.8/7/19 Update. Still love the chair, but do have one feature request. This is especially true in the summer months, though I wear shorts year round. Be aware that the kneeling can feel somewhat scratchy on your knees after a few hours when wearing shorts, and I assume a skirt. So, I would prefer if the kneeling pads were not this kind of fabric. I would prefer leather, or some material like that I think. Also, it would be good if it wasn't absorbent for those times when you are warm and potentially sweating.
