from CONWAY, MA – Verified Buyer

Keeps my back in alignment better than a regular chair. Takes some getting used to, especially in the shin area. One should get up and move around frequently anyway. It could be improved if the spindle was adjustable, not all bodies are alike! Overall, I like it and would recommend it to a friend. Pros: Seems well made and I like the finish, foam is comfortable. Cons: Spindle would be better if it was adjustable. A natural color finish would be good.

Easy assembly, comfortable for the most part

from Mesa, AZ – Verified Buyer

The chair was easy to assemble and the instructions were straightforward. The chair is fairly comfortable with the memory foam. However, perhaps it is just me but my circulation below my knee gets cut off after sitting for 30mins. I have to get up for a couple minutes and before I can sit in the chair again. But it has helped with my lower back and posture.

its ok

from san diego – Verified Buyer

i use a similar chair at my office so i thought this would be a nice addition for my desk at home. unfortunatly it just feels a little "off". the angle is not quite right and the knee pads seem like they are either too small or a bit out of place. build quality is fine.

Great chair

from Tampa, FL – Verified Buyer

Really like this chairs. Bought two of them, one for home office and another for work office. Had a problem with my tailbone and this served as a good relief from the standard sitting position. Just wish there was a way to adjust each cushion individually, but still a great chair.

Comfy cushions, Cant adjust quite low enough

from Seattle, WA – Verified Buyer

The downside of this kind of chair in general is it lacks quite as much height adjustability as a normal office chair has. Im not that tall (57) but with my desk setup I find myself wishing I could adjust the chair a couple inches lower... I find myself looking down at the monitor and that makes me slouch more than I would if the chair were lower. I think if they just moved the upper drill hole up a couple inches, or had more than one drill hole so you could pick what range of heights you wanted and then adjust from there, that would be terrific. The cushions of the chair are memory foam and are quite comfortable, so no complaints there. All in all a good buy, and cheap!

knee chair

from Lafayette, LA – Verified Buyer

seems to be helping with posture and lower back pain. But casters are poorly made and one is continuously working its way out.

Nice at a new height

from Texas

I love the comfort of this chair, however when I first put it together (which was very easy) the seat was very high (even though I'm only 5'1"). Fortunately the frame is made of wood, so I drilled 2 new holes 1 inch below the current holes and mounted the brace through those. Now it's a very nice height for sitting.

I love this Chair!

from Basin, WY – Verified Buyer

I have used this style of chair since 1977. I have a very bad lower back. This chair style helps me sit for many hours doing bookkeeping at my desk without having excessive lower pain in my back. But this chair is set too high for setting at my desk. They do not make it so you can adjust it. The pre Drilled holes for the seat are not centered and the medium srews are to short to use for the seat. Husband has to drill hole to lower the seating section, and realine the holes for the seat.

Had high hopes, but...

from Oregon – Verified Buyer

The first thing I ran into when I got this chair is that, even at its most 'open' setting, still had the top seat overlapping the shin/knee pads, which is too drastic an angle. I have used kneeling chairs for years, but this was noticeably different and not comfortable, putting too much weight on the legs. It took me a while to get used to this, but I had spent a lot of money, so I persisted, and finally started using it exclusively in the office about a month ago. Yesterday, I found that one of the wheels popped off. The wheels are on a metal bolt, which screws into metal threads that are sunk into the wood of the chair. The threads of the bold are totally stripped! I checked the other wheels, and this is happening to them too! I consider this chair a nice idea, but poorly executed.

Comfy padding, nice design

from United States – Verified Buyer

Looks gorgeous. The memory foam extremely comfortable ... I've tried other kneeling chairs, and they were always skimpy on the padding... this chair feels like you're sitting on a cloud, especially since you're shifting some of your weight to your knees ( the knee padding is also fantastic) Glides nicely. Good material. It sits high at the lowest setting, but that's fine with me since I work with a tall desk.
