Ergonomic Kneeling Chair, Adjustable Stool for Home and Office - Improve Your Posture with an Angled Seat - Thick Comfortable Moulded Foam Cushions - Brake Casters

This is my second kneeling chair. The first was a wood construction with 2 relatively thin pads or cushions. I have 2 computers in my office and it was tedious to move the wooden chair (no wheels) to both workstations multiple times a day so I decided to get a 2nd kneeling chair. I have chronic low back pain with sciatica so a regular office chair does not work for me and the kneeling chairs work very well for me. I am 5' 11" and 218lbs.The good: Very easy to assemble; very thick seat and kneeling pads (4"); comfortable; adjustable in height and space between seat and kneeling pad (in other words, room to stick your legs through); and locking wheels.The bad: Nothing really bad here, however they could have put a few more holes in the frame for additional adjustability. Directions are ok for assembly, but horrible for telling you how to adjust for your body type, and how to use the adjustable support assembly. I had to take apart and reassemble a few times to get it to fit me. Not rocket science, but I had to find out what I needed to do on youtube.The ugly: Nothing ugly, might be nice to have a little more adjustability in the seat to take out some of the steep angle, but with the adjustability support rod I was able to get the seat position comfortable enough. As with all kneeling chairs it takes some getting used to as your weight is mostly supported by your shins. For me I have been using kneeling chairs for 6 or 7 years so there was no adjustment time for me, but if you are new to kneeling chairs you will need to stick with it until your body (shin) adapts.In summary, this is a step up from my wooden kneeling chair. Adjustability and thick pads go a long way to being able to sit upon it for an entire office day. I can sit pain free most of the day. Chronic back pain sufferers get use to a tolerable level of pain and kneeling chairs help. Wheels make positioning easy. Great chair, good price. When this wears out I will buy another.

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 this Dragonn chair as well as the 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 am 6'1" male, 190 lb, sensitive shins, home office worker. Assembly of the chair was OK, I had no problems. The main problem with the chair is its knee pad. First of all it is not soft enough. I had to add a folded soft blanket to it to be more gentle to my knees/shins. It would have fixed the situation if not the second problem - the knee pad is bolted to the lower bar and it is too horizontal.When I sit on the chair, my feet naturally want to go down a bit to touch the floor, but the knee pad is too horizontal for it, and my shins are pushed against the back edge of the knee pad at the angle, which is really painful. There is no way to adjust the angle of the knee pad to make it parallel to the natural position of my shins. You can actually see this on some of the photos in the product description. I wanted to hack my way through this problem with some makeshift spacers to elevate the front part of the knee pad, but the way the bolting is done on the pad does not allow any modification to its position that does not involve drilling.I can push my shins a bit forward so that the pressure is distributed at the middle of my shins. This way my feet are not cantilevered that much and shins are not at the angle with the pad. But it means that my knees are bended too much and that much pressure to my shins cause pain after several hours of sitting.The most comfortable position I have found so far is with my knees on the knee pad and my toes are on the lower bar of the chair. This supports my feet higher so that my shins do not push against the back edge of the knee pad. This is far from ideal, though.I like the concept, but I do not like this weird angle of the knee pad. I am debating myself on what I should do with the chair: return it or just drill the stuff to modify the pad's angle.
