The pneumatic back rest is just plain uncomfortable. The pneumatic "cushion" does not even affect it's overall comfort because it is located behind the hard metal supports. It also doesn't aid in making the lumbar area more curved to better support the lower back because the metal support don't flex at all. The only reason I think the pneumatic "cushion" was added is because this is not the first complaint about how hard this thing is and how thin the covering is that really should be more comfortable. It does accomplish an upright position because one doesn't have a choice but to sit upright but in ergonomics we need things to be comfortable enough so that the person can relax into the supportive position. This is definitely not what I consider an ergonomic, value added product.

Like most I wanted to sit better, but unfortunately for me I just couldn't get this to work. I don't know why, I'm 5'3 and found the support hugged my entire back. Couldn't find the right spot to rest it, tried lower and higher but still found my back hurting even after more than a week of use. I got a friend whose much taller than me to try it out as well, they're almost 6ft, and they couldn't find a good spot to rest it either. So I guess beware if your body isn't 'typical', maybe my torso is to short or too long.

didn't like it on my fist try, just keep it for future need just in case. I dont think its practical since it takes some seat space and your booty will not be cozy.

The device is too tall. I am 6 feet tall and it digs into my back under my shoulder blades. After I've been sitting for a while, my lower back begins to hurt and the backrest causes more pain until I have to remove it. I have tried starting with short periodsand gradually lengthening the time I use it, but it doesn't help. It is unusable.
