Comfortable moveable tiltable. This is made well and solid. Slides under a standard desk if you want to go between chair and stool.

I have been a standing desk user for several years. Over the past several months, I've found that my ability to stand for extended periods. At the same time, I was really noticing that I wanted to send to get some relief from the tightness in my hips and upper quads from sitting. But with just a standard desk chair, I only had two positions, stand or sit. With this stool, I can dial it in to give me a balance between getting support for being close to standing and moving it down so I am closer to sitting and avoiding the tightness in my hips and quads. The amount of wobble lets me get a good angle on the seat for support when I'm closer to standing. It does not have a back, which can be tiring, and I retreat to my chair. But this allows the stool to encourage strengthening in my low back. It is very solid and the handles make it easy to move.

So far I've loved this stool. I can really feel my core engage compared to a traditional desk chair, and I feel more alert. The stool does sit a little high at it's lowest setting, but this is fine for me, as I have an adjustable standing desk. The one critique I have of the stool is that the cushion is not very comfortable, and my butt gets fairly sore, or goes numb after about 40 minutes of using the stool. Overal, I'm happy with the purchase.

It's amazing. Solid AF and okay to sit in, but somehow motivates me to get standing at the right height (because the chair is so tall). And the finish is pleather so it stays clean. Amazing.

Terribly uncomfortable chair. I feel like I am sliding off the front of the chair and it makes my back ache. The only comfortable position is leaning it back until the front of the base is off of the ground. Otherwise it puts pressure on the lower back. It appears to be a quality chair and the raising a lowering mechanism is smooth.

I’m 5’10” and even on the lowest setting my feet don’t touch the ground. I have to sit on the very edge of it with my hip elongated and add a foam roller under my feed so my legs don’t fall asleep. At the highest setting cant even get on it to sit. Would recommend for people 6’2” on up but not comfortable for anyone shorter than that.

This chair might not be for everyone, but I love it! If you're looking for a chair that's going to cradle you and allow your hips and back to fall asleep in quiet, stiffened death, then this is not the chair for you. If you need a chair that is comfortable for your bottom, where on a non-carpeted surface you can easily maneuver the chair to sit or quickly stand, allow legs, hips, pelvis and torso to move fluidly, and that automatically puts you in better posture as there is literally nothing to slouch into, than this is the chair. The only thing I added to the set up is a stool in front of it as there is nothing on the chair for your feet to push your body up onto in certain positions you might find yourself in as you move from sitting to standing to sit-standing. For me, it's exactly what I needed to aid in getting my body back in open, mobile alignment and the perfect ergonomic adjunct to all the other functional movements I have committed myself to. I'm happy.

I will update this review as time goes on. So far, this is a huge improvement over the generic office chair that I have been using. I am 6'2" tall @ 200lbs, my desk is 31" high and my old chairs seat was 22" high. That combination meant that my arms were elevated to use my keyboard and my knees were slightly below 90 degrees when sitting with "proper" posture. Because my arms were elevated, I had to use the arm supports on the chair to prevent my neck and shoulders from cramping, which they still did after a long time in the chair. In addition, my old chairs back support was too far to the rear and at a poor angle and promoted poor posture, with a tendency to lean back into the support instead of sitting vertically with shoulders back. This chair assembles in minutes and looks pretty well made despite its country of manufacture (a negative selling point, in my opinion). At its lowest height setting it is just about the right height for my desk/height combination. My arms and legs are both at slightly greater than 90 degrees when sitting in a comfortable position with proper posture. The chair almost forces you to use proper posture, as slouching is immediately noticeable and you have no back support to lean back against. This is one of the reasons this does not have 5 stars currently, but may be upgraded to 5 in the future; this chair can be exhausting to use all day! Some days I am primarily in our factory with very little sitting and some days I am almost entirely in the office. I currently cannot get through a 10 hour day using only this chair. After about 6 - 7 hours I have to go back to the old chair for the rest of the day because my back muscles are exhausted. I believe this is my own lack of conditioning and not the fault of this chair. If, in time, I am able to get through the day with just this chair (and no negative events otherwise) I will update the review to 5 stars. The only other notable thing to report, which is a minor nuisance, is that the swiveling seat tends to "learn" a new position if you twist in it for too long. I spend a lot of time collaborating with other workers in my office and if I swivel around to talk with them for a few minutes, the chair seat will remain pointed toward them instead of "snapping" back to the forward position. I haven't attempted to see if this is an assembly problem or an unfixable feature of the gas cylinder in the chair. It is easily fixed by simply swiveling back to the forward position and remaining there for a few minutes. It doesn't really affect the function of the chair in my opinion, so I haven't deducted anything for it. Overall I think this is a good option for anyone who feels cramped in a standard office chair, or those with taller desks. Just be prepared to switch back to the old chair if you get tired using this one! I am considering converting to a standing desk, so I will also report on any findings related to that. This chair extends to a height that is plenty tall enough for me to use it standing/leaning. Another plus for those of you who already have standing desks. EDIT: I have removed 3 stars. I still like this chair in concept, but it is just slightly too short for me at 6'2" tall. I have moved to a full standing desk from the one noted above and the height of this works for alternating between leaning and standing fairly well, but there is one big problem. The front edge of the cushion has a plastic support inside of it to help retain the cushions shape. This lip curves upward and ends up digging right into your thigh/buttock if you lean there for more than a few minutes. It is certainly a motivator to stand up again, but it is not healthy or ergonomic! Finally, while I was leaning against it today I heard a loud pop and nearly fell backward off of the chair. The screws holding the tilt device halves together pulled out of the plastic, leaving no resistance on the base of the unit. I took it apart and added longer screws to be able to use it for a bit longer, but this chair is destined for the dumpster. This was a good learning experience, however. The next chair will be ergonomic, certainly more expensive and more Made in America...

Wow. Vous mettez le poteau dans la base et le siège sur le poteau et voilà! Vraiment stable, je suis impressionnée. Ça fait que 2 heures que je l'utilise et je capote!

Soft Swing swing: very cool Pfffff go down Ptsssssshhhhhh go up Swing swing! Ok, sit still ! Relax, yeah I love it

Llegó rápido y en buen estado, super practica y el ensamble es solo untar 3 piezas, funcional y práctica, esperemos que el amortiguador funcione por un buen tiempo

It's a very uncomfortable chair - no matter how much I adjust the height of my desk! It tilts forward so you slide off. I would rather be in control of whether I tilt and to what degree.

Los materiales de sienten de muy buena calidad pero debes tener en cuenta que no es una silla. Para estar trabajando un rato es bastante cómodo.
