Not comfortable.

I tried this chair due to back problems, 5 minutes in it and it wrecked me more. The position of the backrest pushed me too far forward and could not be adjusted enough for me to get comfortable.

Horrible

My buttocks only makes contact in half of the seat since you can not adjust the seat. So basically Im slipping or sliding off the seat.

Ergo kneeling posture task chair with back

I want to return it. It causes too much pressure on my spine. I may order a different style.

Back Relief :)

The only down side is that the back is not adjustable. But, after 1 hour of sitting in this chair, I could feel the difference. After 1 week, I have no more lower back aches. I highly recommend this chair.

Not adjustable

Well, you want this to fit your body, so you can knee on it for quite a while. But the design is very disappointing. It has a lever adjust up and down, but it move all three piece together, which doesn't help anything. I am 5'7 and 130 lbs woman. The back support is too high in my mid back and pushing in on me. The knee pad is too close to the seat that my legs are folding too much. Each piece's height and angle should be adjustable independently to fit your body, this design has all the potential but went cheap.

So NOT ergomonic!

The back of this chair nearly pushes you off of the seat, and it does not adjust. When I took the back off to see this would help it is obvious that the seat is angled to high to ever sit in a comfortable position. I returned it immediately. I am of average weight and size and height, but this chair was all wrong. too bad because I am trying to find relief for my sacrum/tailbone pain when I sit. This was not it!

Just what I needed.

Well made and the back is adjustable. I found that wedging a spacer in between the back post and the base puts the back in the perfect location for me. I am enjoying the chair. Therapeutic if you have back trouble.

I like it!

Wasn't sure when I ordered this chair what it would be like, but I've had it for a week now and I really like it. I am 5' 2" and it seems to fit me really well. My husband says he finds it a bit too small so it may not work as well for a bigger person. I do find that my quads get a bit of a workout they're not used to but my back feels great. It keeps me sitting upright. It was easy to put together. I find I can't sit in it all day so I will switch chairs if I have a long day in the office. My chiropractor says that's normal. No chair is appropriate to sit in for a full 8 hours. I would definitely recommend this chair.

Terrible design

When the back is installed and secured properly, it pushes the sitter so far forward they would be eating their desk. There is also no adjustment for the length of the leg or the preference as to how the legs sit under.

JUST TAKES A LITTLE MECHANICAL ABILITY!

This chair is fine - that is after you put it together and correct a manufacturing defect. I ordered two of these chairs - the second one had the same problem as the first one.

Nice Alternative But Not Perfect

Put it together without much trouble and has good padding but is not as adjustable as I would like it to be. The seat height goes up and down but you can't alter the distance between the knee pad and the seat to account for the length of your legs. Nor can you change the angle of the back rest which tips very far forward so it essentially pushes me to the edge of the seat. I had to wedge a piece of wood under it to tilt it back some. And you can't change and fasten the angle of the knee pad (it does tip and move though) , which would be good to accomodate users of different heights. I am only 5' tall so height adjustments are crucial for me.

Needs Adjustability

I love the concept but the chair needs adjustability on seat and knees - length and angle. Also, back rest is way too far forward- had to remove it- needs adjustment also.

Very comfortable chair!

At age 63, I still enjoy sitting with my feet under me. In a traditional chair, my legs/feet go to sleep from sitting on them. This ergonomic chair allows me to sit comfortably at my computer for hours. I have purchased two of these chairs for two different desks.

Back Not Adjustable

The chair came quickly. Easy to assemble. Unfortunately, the back of it is not adjustable, and pushes you forward in an uncomfortable manner.

Love My Chair

My chair is about 2 years old now. I practically live in this chair, and it is WAY better than the standard-issue office chair. No more neck, shoulder and back pain, and much better posture, in and out of the chair. I just feel better. That said, significantly better padding for the knees / shins would help tremendously. A laptop case with neoprene padding used as a pillowcase over the knee r

Good Chair

Chair helps with sciatic nerve issues. Angle of the knee cushion is much better than another model I purchased last year. The back support pushes the body a little too foward so I removed it.

Good Buy

I have herniated disks and bought this chair for work. It has been a great relief from any of our office chairs. The directions were sketchy but good enough, the back does adjust a bit if you loosen the spring below the seat, but still considering removing it. It is comfortable, stable, rolls easily,and takes the pressure off my spine. I'd buy it again.

Not Good For Short People

I'm 5'2, female, and this chair would be fine for someone average height like 5'5 or taller. You cannot raise the knee pad up so I cannot make the knee pad close enough to my knees so I end up sliding down the seat and constantly having to push back up. This makes the chair pretty uncomfortable for me. I have not found a good chair for a person my height at a reasonable cost. I now spend the da

Minor Modifications Worth The Effort

I tend to agree with the other reviews, a pretty good chair that actually makes my back feel good, for a reasonable price. The backrest was pushing me too far forward so I took the spring (part K in the assembly instructions) out of the adjustment knob and now it goes just where I want it. I haven't had the chair that long yet, but at some point I may try different length bolts and spacers (any

Short Person Happy With Purchase

Since I'm short and weight 90 lbs, back was too high. Just removed it and very happy with swivel seat and rollers. Very high quality construction. Put the lumbar pillow in car and it works great. Very happy with value for price and quick delivery. Easy assembly, holes matched easily.
