I'm a freelance writer and spend a LOT of time on my laptop. I wanted to find a chair for "active sitting" so I could take some pressure off my lower back. I don't have back problems, but I periodically spend SO much time sitting that I'd get uncomfortable after the first 4 hours or so of a long editing project.I really like sitting/working on an exercise ball (seriously), but hubby over-ruled that idea for my kitchen workstation, simply because it was not quite Politically Correct and clashed with the furnishings : ) Plus, the cat likes to punch and chase the giant ball. He was right, as usual. This kneeling chair ended up being the PERFECT answer for me.I had been using a very nice, expensive office secretarial chair, but always found myself sitting on the front edge of it, with my feet wrapped around its leg stand so I could keep my posture comfortably erect. When I saw photos of the kneeling chairs, I KNEW THIS was my answer. The only question was whether to go with wood or metal, rolling or not, which type of adjustment, etc.I'm an admittedly obsessive "pre-reader" of Amazon Reviews before making ANY purchase (this is getting to be a real problem at the grocery store, BTW), so I spent my obligatory hour or two of research before going with this model and I'm glad I did; it's the perfect fit for me.1. It's comfortable! I like being able to sit upright and the knee support makes this very easy. I can even fold my legs under and behind me, which, for whatever reason, I find incredibly comfortable and relaxing.2. Looks GREAT with our kitchen furniture (oak table, rolling grey Chromecraft chairs with oak). Although this is a slightly lighter shade of wood, it blends well. Metal would have been a mistake for this reason.3. Seat and kneepad is comfortably cushiony. I'll update in the future about how well it wears, but it looks promising to me. Plenty soft for my tastes, but I am somewhat Spartan in my approach to life. If it suits its purpose, I'm a happy camper. These pads are soft enough, firm enough, and look tough enough to do their jobs.4. Wheels are a NECESSITY. I did not realize it until I got the chair, but you need to be able to stand over the chair and then make a fine position adjustment just as you sit. Kind of like mounting a horse. I wouldn't want one that didn't roll for that reason (I AM up and down about a hundred times a day, so this matters to me).5. Feels solid as you sit; I find it very comfortable. I'm relatively short (5'4") and use the middle of 3 positions.I highly recommend this product; it's reasonably priced, easy to put together, and "sits great." A winner!P.S. 6/4/13 Update: Still researching? I just checked for you; Wikipedia has a detailed explanation of the advantages of "active sitting," for those not familiar with the concept.6/30/13 FYI Update: BUMMER! Though I still love this chair and still recommend it, I DON'T RECOMMEND it as a "permanent" everyday office chair. I correspondingly adjusted my star rating from 5 to 4.Why? After sitting on this every day for 12-14 hours for 6 weeks, I began to notice that my hamstrings (muscles in the back of the thigh) were actually shortening (I stretch daily). Then it dawned on me: this is a natural result of the bended position of the legs for 8-10 hours a day, of course, a factor I didn't initially consider. Fortunately, I noticed in time. Shortened hamstrings not only make you feel stiff (and short), they also impact your back alignment AND your ability to balance. No harm done for this short period of use, but this could potentially cause problems after years of sitting this way, in my opinion.So now, though I REALLY like sitting in this kneeling chair, it's relegated to a TASK CHAIR in my office. I do use it for several hours a week and it is a go-to favorite for comfort, but I just don't think any kneeling chair would be a suitable permanent replacement for an office chair for me. But for occasional use, it's still terrifically comfortable.I don't know why I find the info I need AFTER I buy something...If you do a search you can find a few reliable research papers about kneeling chairs. Here are what I think are the pertinent facts from the research:(1) The angle of the seat needs to be at least 20 degrees. This chair can do that.(2) You should end up sitting in a slightly forward position, as you would be for writing or sewing. If you are sitting back on the seat you posture will be wrong, i.e., your weight should be on your lower legs, not your tush.(3) These chairs are a little hard on the lower legs. They restrict blood flow and put pressure on your shins and knees (kind of depends how you fit on the chair). Not recommended for prolonged sitting!(4) None of the reviews I saw address this, but it's rather awkward getting in and out. Do you straddle it from behind like a rodeo cowboy or do you sidestep your way in? Either way there is a very real possibility of getting your foot caught and keeling over.(5) The seat does not swivel (I knew that) but until you try it out you may not realize how often you need to turn a little to the side, or you may not be aware that you use the swivel motion to get in and out of your normal computer chair. The non-swivel puts your back at risk from awkward twisting motions.(6) Kneeling chairs tend to fit shorter people better. There just is not enough built-in adjustment for long legs.#1 to #6 are not my opinions, they are from reliable research. Here's a few tidbits from yours truly:(7) The directions are abominable. I almost sent it back in despair, and then in the middle of putting it together I almost sent it back again because I could not get the holes to match up. As another reviewer said, just start by putting the tubes in place (which don't look much like the illustration). The cushions simply screw on with four bolts and washers each, so set them aside. When you're attaching the giant adjusting screw/bolt/riser, keep in mind that you can screw both ends in or out till the holes match the holes in the wood. It still took me less than an hour. Not much to it really, once you figure it out.(8) The adjustment bolt has a LOT of adjustment, way more than the one inch someone mentioned. However, I wish I had unscrewed the bolt all the way before I put the chair together because now I'm nervous about at what point will the bolt come completely out of its socket? At what point have I compromised the integrity of the chair? I'm surprised the paperwork doesn't say something about this. You know, kind of like how you wouldn't pull the 2 halves of a curtain rod so far out that there was only an inch of overlap.(9) I totally do not understand why some people make a big deal about it being way higher than a normal chair. That is not the case for me at all and I tried it at two different computer desks. I have about 2 5/8" of bolt showing. At its lowest position there would be 1/4" showing. As stated in (8) above, I have no idea how much higher I could unscrew it to, so maybe at its highest yes it would be unreasonably high. I can't imagine it being comfortable at that angle.My Final Thoughts:I like the change of position this chair offers but I think I'll end up paying for it with problems elsewhere in my body (lower legs or knees). Also I tend to be up and down a lot and I think it's just a matter of time before I get my foot or leg hooked and end up on the floor (hopefully not with a broken leg but I see the possibility).I feel it's a decently made chair and does what it says it does, hence the 4 star rating. Watch the prices! All over the place, different prices for different colors, etc., you can pay half or double.So even though it's a hassle and I'll have to pay postage, I think I'm going to send it back. There were no kneeling chairs in the stores in my area so this was the only way for me to try one out. I had high hopes but excuse me, I have to sign off now, my legs are bothering me......Update: I have been using this for 4 days now and found that the padding in the bottom seat (under bum) is not sufficient, so I am now using a gel seat pad (purchased separately) to help out my tailbone. I am still seeing major improvements in my posture and back pain though.Original review:I was having a lot of lower back pain while working from home, and decided to try out a kneeling chair. I was familiar with them, as they were quite popular in the 80s but hadn't sat in one since then. The chair was fairly easy to assemble and took me perhaps 20 minutes total. The adjustable seat height was what drew me to this chair, as well as the classic design. As with all kneeling chairs, it's a little awkward to sit on at first, but once you have the correct height dialed in for your desk, you should notice an immediate improvement in your posture. The chair tilts your pelvis slightly forward and reduces pressure on your lower back. Although you could slouch on this chair, it is way more natural feeling to sit upright. Important to note: When you raise the seat height, it does increase the angle of your seating and therefore can put more pressure on your shins, which is not ideal. You want your shins to be resting on the shin pad, but not supporting your entire body. Your butt should really bear the weight when you are seated properly in a kneeling chair. When I increased the chair height, I noticed that there was too much pressure on my shins. I had previously ordered a soft foam/gel seat pad on Amazon for my old desk chair, and I am now using that under my shins. That ensures that the proper angle for my knees and posture are maintained. Overall I am quite happy with the chair! If you are on the fence and looking at other models, I would recommend that you try this one out!The product is different as the one in the pictures, which is annoying considering you're paying quite a bit for something that isn't what you expect. When building the chair I left the seats for last so I only realised then they were not like the ones the description pics show. The design is completely off. They're square! And also look and feel very cheap (there's threads coming out in many spots, makes me think this won't last long) which was a surprise considering the wood frame is quite nice. Was really excited about this product as I loved the design and truly thought would be great for my back pain, not what was expected tho.Simple, does the job and fairly good on the eyes considering it's not a fancy brand one.This alone doesn't solve all your problems so you do need to still figure out how it works best for you (e.g. what height etc.). I also wouldn't advise sitting on it continuously for more than a couple of hours, make sure you keep moving.This product broke after only 3 weeks normal office use. I did not report within the 30 day Amazon window but did not think that was important as the product is defective and broke on a faulty design/manufacturing part. See photos, a thin weak piece of MDF is used to connect the seat to the frame, the point taking the most stress. A simple peice of wood or plywood would have prevented this, but they cost a few cents more than MDF for a piece this size. Almost like it is designed to fail here after the 30 day warranty is up?? Anyway, UrbanInspirations denied a return referencing the 30 day period had expired. If this is the sort of company you wish to deal with, be my guest, i wont deal with them again.Redresse spontanément la posture en faisant basculer le bassin . Il soutien la colonne et le ventre simplement par son design. Parfait aussi pour la méditation. S'ajuste en hauteur simplement en ajustant la base à différentes hauteurs. Ma femme s'était fait faire un fauteuil ergonomique à sa mesure qui couta des milliers de dollars. Mais qui ne soulageait point ses douleurs au dos. Alors que celles-ci ont totalement disparues avec ce fauteuil qu'elle possède depuis quelques années. Avec ce fauteuil, je n'ai plus moi même maintenant à me préoccuper de songer à redresser ma posture. Ce fauteuil le fait pour moi. Vivement recommandé.Easy to assemble. Small wrench to tighten included. I’m over 6 ft. and I have the chair at it’s lowest setting so there’s lots of adjustment available I’m at a higher table. Or if you are a shorter person. My ankles do touch either side of the base but this is a minor irritation. Looks great. Takes up way less room and space than a regular chair. I’ve been able to sit in this chair longer than my previous high back chair. There’s not much pressure on the knees at all. The knees really just seem like for stability. The padding on the seat and knee rest are generous. Looks great. Feels great.
