I am not a fan of standing desks but needed something to help mobilize my hips. This has been a great tool. I have an adjustable keyboard tray and the height was perfect for me, and what I kept my chair at previously.The only thing I have to note is that some of the screws needed to be retightened with an allen key to keep the pads from wiggling, but that was an easy fix.

Ergodinamico, he usado este tipo de silla hace años este no es tan cómodo muy duro el apoyo para las rodillas y en algún momento hay una ligera presión en las lumbares, con el sencillo que tengo no me pasa creo que es el ángulo

This is a comfortable and pretty well designed chair, BUT for me, a 175 pound man it didn't even last 2 years before one of the metal cross pieces cracked and renders the chair useless. The other pieces (cushions, and rails) are sturdy and would probably last several year. However, they need to either use stronger braces or provide replacements if mine was the only one defective. I would be willing to purchase several more braces, if they only cost a few dollars. I still see this product on sale from several vendors, so if they are willing to sell to me, I'm interested to get a supply. My rating is based on the short lifespan of the cross-braces that hold the rails in place.

I can sit the "regular" way, but my favourite way to use this so far is with my feet up on the knee rests.I love the rocking motion!!Beware the crossbeam at the front though. The first time I sat on the chair, I had my foot under the crossbeam and crushed my toes. It only takes once to learn that lesson!I love the versatility. As someone with ADHD and a bad back, I really like this option.The seat is higher than my old office chair, so I'll need a monitor stand to bring it up to eye level for optimal ergonomics.The knee rests are quite firm at first, but I can already feel them getting softer with more use.Whenever your core gets tired, just change positions and rock away!

TLDR: Amazing quality chair, super comfortable/functional/looks great! Incredible company, so helpful/friendly/informative/accommodating/passionate (plus it's a women-led! Support a girl boss!). Out of all the ergonomic chair options I can't recommend this one enough!!!I could go on forever about all the things I love about this chair & my experience buying it! I knew I wanted a more ergonomic chair and did a LOT of research before deciding this was the best option so save yourself the time & take my word for it. The things that set it apart for me were:1. Price - it's a perfect middle ground, anything cheaper & you'll sacrifice quality, anything more expensive & you're probably getting something way overpriced.2. Quality - if you compare it's specs to others like it, it is just built better. Thicker cushions & a sturdier frame that I know will last. Incredibly comfortable.3. Looks - not the most important factor of course but I would definitely prefer my furniture to look nice! The chair looks great! I love the high quality fabric & wood, plus it can easily be tucked away under my desk when not in use giving me some extra space.4. Company - I really care where I buy from. I want to support companies that I admire & this is a cool, transparent company that obviously really cares about their customers & the quality of their products.Other things I like about the chair & the company:-I have a desk with a top drawer which is a problem for my regular desk chair, I can't tuck in when I work because the arms of the chair hit the drawer. With this chair though, I can sit as close to my desk as I want with plenty of room for my legs!-I fidget a lot when I sit & love that there is a bunch of ways to sit comfortably in this. Plus you can rock in it & being able to move a bit while I'm working is sooooo great.-The company is female owned & operated which is something I love to support!-I also exchanged quite a few emails with their customer support & they always responded so quickly. They were so so friendly & helpful with all of my questions, even before I bought anything! Throughout the entire process the amount of passion & care they pour into this company & their products was evident.-Assembly was fast & easy! They send you a complete assembly guide plus you can find the guides on their website along with video walk-throughs.My only drawback:Realistically this is a problem with my set up & not the chair, but if you work mainly off a laptop it is something to consider. I usually work on a laptop & now that I'm not completely slouching over the screen is a little low. I would recommend either setting your laptop up on something (a laptop stand or even just a box) or using a monitor that is at a proper eye level.I'm sure almost no one will make it this far but all I have to say is I love this chair & everyone should get one!!!

I knew I wanted a kneeling chair, and I spent about a week doing my research into the different brands and models before I landed on this one. My priorities were comfort, affordability, durability, and aesthetic design.There are a slew of terrible reviews here on Amazon about the set-up of this chair, so that had me biting my nails as I hit "add to cart". Fortunately, I had a much easier time than others seem to have had! My package arrived 54 minutes ago, and I just finished putting it together and am sitting on the chair as I type. Here's the breakdown:Set-up: 3/5. I would recommend to Sleekform that they re-write their set-up sheet, as it was often unclear which direction to place objects. (I'm still not sure if the knee pads are supposed to splay in or out, but they're comfortable splaying out for now, so I'm going to leave them.) However, all my assembly items did arrive in the correct number and quality and with the correct holes drilled, which seems to be something others did not experience. It did take me a while to put together the chair, but that's not an insurmountable obstacle for me.Quality: 4/5. Others have commented on the "wobbliness" of the chair; I'll concur with them there. I screwed each screw in securely, but the lack of front bar (near the knees) makes this seem a little unstable if put my weight on one knee pad to get up out of the chair. I do hope it'll be fine in the long run though; it's nice to have a little "give" in the wood. I do wish the wood was available in other stains but birch - I'm going to have to figure out if I can stain it to match the acorn-colored wood of the rest of my office. Similarly, I don't like the black fabric - it's quite scratchy. After watching a few youtube videos about reupholstering chair cushions, I think I'm going to try doing that with a durable velvet that's easier on the knees and thighs.Comfort: 5/5. Yep, I think this chair and I are going to get along fine. I hate sitting - I'm a teacher who spends all day on her feet - and when I have to do so for more than a couple hours at a time my lower back HATES me. Quarantine has necessitated a lot more sitting than my job usually entails, so I'm extremely glad to have this chair. I'm effortlessly sitting with my spine comfortably aligned, and can feel the tension releasing in my lower back and shoulders. It's great. I'm glad I got this chair.

I normally opt for the most expensive product in a given category with the assumption that it is made from different materials and ultimately will have better quality. When shopping for this chair, I found a much more expensive brand, nearly three times the [rice of this, that I considered. I could not help but think it was way over-priced for what it was. I decided to step down a bit in price and I am so grateful that I did.The chair was extremely well packaged and each part was labeled, making it easy to assemble. The only complaint I would have is that it was somewhat unclear which direction the cross supports should be facing and the diagram was wrong. That said, it's pretty obvious when you look at the cross pieces that they are longer toward the kneeling end than the seat end. For that to work, the cross members are angled slightly. By looking at them, or holding them upright on a flat surface, you can see that they lean one direction or the other (depending upon which way you have it facing. Obviously, given what I mentioned earlier about the kneeling pad end being further apart than the seat end, the angle should point downward toward the seat to make that happen.In the manual that came with it and in other things I have read or seen online, they suggest starting out in shorter periods of time,m then working up to a full day. They also mention to shift your position from time to time. I had no problem using it the entire day immediately. I do shift my position often, but generally find this to be as comfortable as a seating chair.As as bonus, I have learned that I can use the natural curves of the chair to stretch my Achilles while sitting on it. I have plantar fasciitis, which as a runner is quite painful and hard to get rid of. I have found that I can gently stretch my achiles, one of the main exercises for controlling the pain.Used properly, you can really focus on your core and exercise your abs while working. If you happen to be ADHD, like me, this chair may help you to focus.With regards to quality, I suppose time will tell. The padding is thicker than some of the competitors, but I do not necessarily think that is better. At the end of the day, it will become about how long it lasts and how the material it's made from compresses.All in all, I highly recommend this chair over the more expensive Balens product. The Balens product does offer an interesting option to add a back rest, but I feel like that is unnecessary and contrary to the intention of a kneeling chair as it takes you out of your core when you push your lower back toward the support, which is the natural tendency. You would have to be pretty disciplined to not do that. As long as this product holds up fairly well, I will never know if it's equal in quality to the Balens product.8/7/19 Update. Still love the chair, but do have one feature request. This is especially true in the summer months, though I wear shorts year round. Be aware that the kneeling can feel somewhat scratchy on your knees after a few hours when wearing shorts, and I assume a skirt. So, I would prefer if the kneeling pads were not this kind of fabric. I would prefer leather, or some material like that I think. Also, it would be good if it wasn't absorbent for those times when you are warm and potentially sweating.
