Boss Office Products Ergonomic Kneeling Stool in Black

A kneeling chair does get your spine into a neutral position if the seat is at the right angle for you. Some things to consider are seat angle and whether it's adjustable, distance from seat to kneeling pad, how the seat height is adjusted, and the quality of frame, cushions, and wheels. I read a lot of reviews and was considering the one made by Dragonn, the one made by Boss (the only model that I found that has a pneumatic gas lift height adjustment), and the Sleekform Alpharetta model (the only model I've seen that has a seat angle adjustability feature). However, the Sleekform Alpharetta is sold out everywhere, so I purchased the Dragonn chair as well as this one made by Boss to compare and see how they felt.Unfortunately, in most of these chairs, the height adjustment is directly tied to seat angle, so the higher you set the seat, the deeper the angle of the seat. Also, if you're not an average height person, there's no way to adjust the distance of the kneeling pad from the seat, so for me being 5 feet tall, with very short thigh bones, I have to sit pretty far down on the seat to rest my shins on the knee pad, and there's no way to change that. I took a photo of the Boss (black) & Dragonn (gray) side by side in the lowest position and highest position, and you can see the Dragonn adjusts much higher, but also gets at a very steep angle. I do not have to use the chair at a desk all day, this is just for a couple hours of work at a time, so I do not need a chair that I could sit in for 8 hours. In that case, I would recommend having a couple of different options, so you can change positions/seats and from sitting to standing throughout the day.The Dragonn was very easy to assemble especially if you watch the video. For the price, the quality is nice enough. The cushions are well made, but the casters are plastic, not metal. However, I imagine you could get metal casters at the hardware store and replace them to have something more heavy-duty. The cushion is very thick and sturdy, but a bit hard. Also, it turned out that no matter how low I put the Dragonn seat, the angle was too steep for me and did not allow me to have my spine in neutral. Instead, it made me overarch in my low back, which was immediately uncomfortable. In order to adjust the seat height, you have to get out of the chair and turn a screw that slowly adjusts the height, so it's not a chair you can adjust quickly.The Boss was also very easy to put together, but there was no video. For the price (only around $80), I feel the quality is very good - the frame and wheels are the same quality as the Dragonn, but the seat cushions are much thinner. Although the seat cushions are not as heavy duty, I actually found them more comfortable because they are softer. The Boss has a pretty shallow angle at the lowest setting, but keep in mind that having your thighs pointing down is enough to tilt your pelvis forward, so this was plenty of an angle to get me sitting up tall with a neutral spine. Also, when the Boss is at the highest setting, it's still not too steep for me, so pretty comfortable at all settings. To adjust the chair higher, you just take your bottom off the seat, pull the lever and let it rise to where you want. To lower it, you can pull the lever while still sitting in the seat, and lower it to where you want. Very easy and quick to adjust. This was the only model I found with this convenient feature.My conclusion is that that I think it's worth trying a couple of these to see what works for you, because I think the angle at which you feel comfortable might be a little different for everybody. If you're able to get a model like the Sleekform Alpharetta, which has a separate adjustment for seat angle, that probably will allow for the best fit, and I may try that if it ever becomes available int he future. Fortunately, the Boss was such a reasonable price, I felt it was worth keeping until I can try the Sleekform.

I have owned 2 of these and am about to order my third. I have been saved from so much pain because of this chair. I have owned kneeling chairs for 40 years, and this brand for 9 years, and there is no other type of chair I can spend any real length of time in.I know someone left a review about how dangerous these are, but I have had no problems in the decades I've used them. It may not work for him, but it sure works for me!In fact, it has saved me from not only lower back pain, but also upper back and severe neck pain and headaches. I used to go home from work every day with a severe headache from my upper back and neck that was untreatable with pain meds. It would finally fade sometime during the night, and I would have to go back to work the next day and start all over again! I asked my employer for one of these and had instant relief! And it was this particular brand that did it.However, I would like to say that the padding loses its loft very quickly. The manufacturer could try something else that would work better, because the current padding is not working. I have solved this problem by putting a dense pillow under my knees and it has worked well. You may not want to do this, but it works for me.I have another brand with massively thick memory foam padding that has kept it's loft well, but the cushions are so narrow I feel like I am going to fall off at any time. That's why I'm getting this one, because it's wide enough for me to fit comfortably.The only reason I'm getting a new one is that after 9 years of daily use, the pneumatic lift is starting to jam. I think the chair has worked pretty well.For measurement's sake, I am 6 ft tall and weigh about 220 lbs. It fits me perfectly. I have osteoporosis due to allergy medications. At age 50, according to my bone doctor, I had the spine of an 80 year old. I'm now almost 62, and am so very grateful for these chairs! They are the difference between me living in constant untreatable pain and living a normal life.

Cons:The wheels are awful. Had to replace.The kneeling cushion has frayed and come apart at the seam after a few weeks.The kneeling pad could be thicker. If I put all my weight on the kneeler, I can feel the hard part at my shins (afraid of getting bruises).Pros:I like the kneeling type seat.I always wanted to try a kneeler, but did not want to pay $100+ to try one. I am starting to have problems with my hips because I always sit cross-legged on a regular chair. It's starting to hurt. I sit most of the day. So I find with the kneeler, I don't spend so much time adjusting or trying to get comfortable, and it's an easier position to get out of than sitting cross-legged. I feel like it is probably a healthier position for posture and blood flow. Anyway - I bought this one from Amazon warehouse for around $45 - like new as advertised.So I will most likely replace or add to the kneeling cushion and recover it as well as changing the wheels and be happy with it.But I don't think I would pay $100 for it.Update:Same issues but a note about the wheels.I bought new wheels but don't like the way these roll either. Sometimes there seems to be a pause. It feels like I have to get over a small hump. However after replacing the 2nd set of wheels, I have realized this is a flaw in the design of many kneelers. Having 4 wheels instead of 5 as on a normal office chair causes it not to wheel around smoothly. I will continue to use a kneeler because of comfort, but just wanted to share this in case someone else has the problem. Took me a while and some research on office chair wheels to understand why.
