I absolutely LOVE this chair. It is a total game changer. When my company went to full-on WFH, I was super bummed to be leaving the adjustable-height desks we had in the office — since I would stand at my desk for nearly the entire day. Luckily, I already had an architect's table that I could work from. After a few adjustments, I've got everything ergonomically correct, and this chair was the final and most perfect piece to this puzzle. Now I can take the breaks from standing that I need without leaving my architect's table. It's very sturdy and perfect for that half-stand, half-sit seating. I also love that it doesn't just swivel forward and back, but also left to right, so that it's great for a fidgeter like myself. Before the package arrived, I was a little concerned about the base and if it would stay put with all my movement. It is indeed solid and heavy, and I've never felt like I was going to tip over or fall off. If you're looking for a standing desk chair, this is the one! Just buy it already. (: (No I was not paid to say that.)

I wrestled with how to write this review. Heck, I wrestled with how to rate it as well. You see, never have I purchased a piece of furniture whose sole purpose was to keep you mostly upright, and if possible, standing. You are not purchasing this chair for comfort. I repeat THIS IS NOT A COMFORTABLE CHAIR!!!!! What this chair provides is an incentive in spades not to remain seated all day, while you work. In this, it excels. This chair forces you to change position a lot and is, for all intents and purposes, a brief respite from standing. Nearly a month into using this chair 5 days a week, my body has grown so accostumed to barely sitting that I find it hard to slouch in chairs when I’m not working. This is probably the biggest testament to this uncomfortable thing. It promotes correct posture in a way no other chair I have owned has (and I’ve owned some pretty expensive office chairs). So, can I recommend this chair? Sure. Why not…but with a caveat. You should already be in somewhat decent shape if you’re going to bite this one off. Larger people may not find this stool as “accommodating” as smaller framed people. If you suffer with back problems, don’t do it. This is not for the person who has medical issues standing (unless your dr says otherwise). Having gotten used to this chair, I can tell you that it has begun to pay dividends when it comes to my health. However, this is not a one size fits all kinda product and you should approach with extreme caution.

This chair is a great alternative to a standard desk chair. I bought it go with my standing desk. I love the concept that I can sit and my desk and still move. I do twists, side to side and back and forth motions most of the time when I'm seated. It is a great way to build up my core muscles without really even thinking about it. I find that I sit up straighter with this chair so it is also improving my posture. There are a couple down sides to it. I have short legs so even in the lowest position, it is a little high for me but the footstool I keep under my desk makes that a non-issue. I will say that the seat is a little hard as some other people have mentioned. I have found that if I sit way back on the seat and sit up straight, it is much more comfortable. If it gets too hard after awhile, it is time to change my desk to its standing position and set the chair aside for awhile. This is a very expensive chair and I thought long and hard about buying it. At first the hardness of it made me a little skeptical as to whether or not I liked it. But I've had it for about a month now and I am happy that I stuck it out and kept using it. The more I use it the more I like it.

I've been a proponent of a standing desk for several years. As such, I've searched for the best standing stool. I've tried many and have either returned or donated the ones I've tried. Just couldn't find that perfect chair. I decided to try the Vari Active Seat and this one will be a keeper. It makes sense that the maker of premier standing desks would be the maker of a premier stool. The Active Seat feels very sturdy. It's got some weight to it, however, it also has a great carry handle to be able to move the stool if needed. The base is solid. I returned the Uplift Starling stool because it was just too light and it would slide on my glass mat. The Active Seat stays put. Many have said that the seat itself is hard. That is the nature of most, if not all, standing stools. The idea is to perch rather than to sit. Also, the stiffer seat reminds us to get up and move around. Nothing like a little discomfort to get us to do that. This is not a deal breaker for me. The Active Seat also has just the right amount of movement. I can rock to stay active without fear of losing the stool from under me because of the hefty base. The seat also comes fully assembled. Huge plus for me. For the seats I've had to return, it was a pain to disassemble and figure out how to re-box. Of course, this is a non-issue with the Vari because I will be keeping this stool. You will pay more for this stool but it's well worth it if you work from a standing desk. Highly recommend.

These are the best for multiple uses the Quality is unexpectedly great. The movement is a big plus rather than static. I use in public speaking and as a musician. They really are perfect and well worth the price. Don’t go cheap and don’t go exorbitant this is truly just right. If you have a standing desk they would work for that as well

Style: CoreChair
[Edited review from 2 to 5 stars:] The CoreChair shipped to me creaks when moving in it. I uploaded a video showing how it creaks. I left a 2 star review here on Amazon but am now changing my review from 2 to 5 stars because Vari customer support responded very quickly and was excellent. Overall, the CoreChair is comfortable for long hours of work. The seat foam is sculpted to reduce pressure under the thighs and tailbone. Initially, the seat feels a little different and not exactly luxurious. But often the best ergonomic products for working long hours aren't exactly comfortable: instead, their secret is they never become uncomfortable. One isn't bathed in luxury but one also never becomes sore or strained. The CoreChair is good in this regard. The forward tilt range in particular is excellent and almost like using a kneeling stool without the knee pad. I can definitely recommend the CoreChair as long as you get one that doesn't creak. And be sure to reach out to Vari's support team if your chair does creak.

This is a nice chair, but for my purposes, it did not move as easily as it appeared to in the materials. In addition, the lowest height was too high for the other user in our home. Returned it for a refund. All that said, the chair is very sturdy and well made..
