A user experience with this chair
Color: Black Size: Overall Depth 44"
I’m very happy with this chair! It feels sturdy, comfortable, and well made. The mesh design is breathable and provides great support, especially for my back and lower back during long hours of sitting. I also really like the adjustable headrest, armrests, and lumbar support, which make it easy to find a comfortable position. The seat is spacious, and the chair rolls smoothly and feels very stable. It also looks modern and fits perfectly with my desk setup. Overall, this is an excellent ergonomic office chair and a great value for the price. Highly recommended! ... show more

⭐⭐⭐⭐⭐ Comfortable and Great for My Home Office
Color: Black Fm Size: Overall Depth 44"
I’m really happy with this office chair. It has a comfortable ergonomic design, and I love that the headrest and armrests can be adjusted to fit my needs. The breathable mesh keeps it comfortable during long work sessions, and the lumbar support is a great addition. It also reclines smoothly when I want to take a short break. Overall, it looks modern, feels sturdy, and has been a great addition to my workspace. ... show more

Good Chair, Bad Assembly Experience
Color: Soft Black Size: Overall Depth 29"
It wasn't so bad building this chair, however, you will need a rubber mallet (very soft hammer) to tap the arm rests into the seat, as it is an interference fit. The bolts at this fitment are only there to keep the arm rests from being pulled out of the fitment. My right hand side arm rest has a stripped threaded insert from the factory, 1 of 2 bolts refuses to go in despite it being lined up. It appears to be structurally safe despite this, but it is frustrating that this slipped past quality control (if this is ever checked). I tried all bolts, none of them went in 1 of 4 total holes for the arm rests. So be careful when assembling. Aside from this, this is a very good chair. My back has the worst posture ever due to my poor habits when I was a kid. It's taken a lot of adjustments to get it comfortable but it feels good now. My only concern for comfort is the headrest - i wish it could be adjusted further back, as the most rearwards position is more forward than I'd like it to be. Flipping the headrest around does help sometimes. The headrest is fully removable. The cushion is great. Most importantly, there is almost no tailbone pressure. I was concerned about the rollers at first, but they roll very smoothly and easily. A lot better rolling than my leather chair. ... show more

Exceeded my expectations / Do not hesitate to try this chair!
I should start by saying I own another Flexispot chair that cost twice as much and I've been very pleased with it. In fact, it's one of the many reasons I considered purchasing this chair. First, I was really nervous that this chair would not be quality and I might be disappointed since most of it is plastic. However, my initial impression proves me wrong. Despite its mostly plastic build, it's very good quality. I am a small woman with severe arthritis and I had little difficulty in putting this together. The step by step instructions were very clear but admittedly, step 1 made me a little frustrated to figure out. It was not easy, but within a relatively short period of time, I got it figured it out. After that, everything went together very quickly. Took me about 30 mins start to finish. I wasn't expecting to enjoy the footrest - as my other chair's footrest was not as comfortable. This, exceeded my expectations. The footrest pulls out to the perfect length and it sits high enough to leave your legs feeling rested (again, I'm 5'2" so I'm relatively short). It's very padded and comfortable. I also purchased the padded seat as I find the mesh a bit uncomfortable during the summer season when I wear shorts - my skin is super sensitive. After sitting on this chair only about an hour, I love it. It's very firm but squishy. I can't speak to how it'll hold up over time, but if it does - I absolutely love the comfort. I wish there was more adjustability with the arms but I think it's very nice given the price point. I love the back rest - but I will say it takes some people a little time to get used to. Even I didn't like it the first time I experienced it - but now, I can't go without it. I have severe spine issues and this backrest has helped so much when it comes to sitting at my desk for hours on end each day. The color is exactly as pictured and the fabric is very nice. Again, I can't speak to how it'll hold up over time but the warranty itself is phenomenal leaving me not concerned at all. Flexispot has always had the best customer service and I would trust shopping with them at any price point. I own multiple sit/stand desks and now two chairs - this is a very reputable company! Lastly, the item was shipped and packaged well - everything came perfectly wrapped and easy to unbox. Thank you for yet another great chair! ... show more

Great chair for home office
Color: Black Size: Overall Depth 44"
I’ve been really happy with this chair so far. Assembly was pretty straightforward, and I was able to put it together without much trouble. The instructions were clear and all the parts fit together well. The chair also looks really nice and has a clean, modern design. What I like most is how adjustable it is. The seat height, backrest, armrests, and other settings can all be adjusted, so it’s easy to find a comfortable position. I think this would work well for people with different heights and sitting preferences. I mainly use it for studying, and it’s been a great fit for my setup. It feels sturdy and well-made, and I really like being able to customize the chair to what feels comfortable for me. ... show more

This is a torture rack not an Ergonomic Office Chair
Color: Black Size: Overall Depth 44"
I bought this chair back in late November as a Christmas gift for myself as a Christmas gift to myself. I've spent a few months working from home in this chair, and I use that term loosely. Here is the Bad: After a month of use I started having hip pain, but I thought it was from sleeping on my side, or something.... didn't think it was the chair initially. But a couple more months go by and I realize I am getting hip pain sitting in the chair I take my hand place it under my butt and am surprised that the chair is bottoming out on the structure underneath the mesh bottom. OK, I am a big guy at about 285lb which this chair is supposedly rated for 400lb. the structure under the chair is not flat or properly supportive, it is a like trying to sit on a hard thin bar on either side of your hip. Durability: the mesh is even showing some signs of wear in the areas where it touches the structure underneath. I would say, if I could endure the torture of sitting in this chair it would surely wear out in those areas. After swapping out my wife's chair my hip pain started to get better. My wife does not work from home and only uses it a few hours a week and she hated the chair too. Sitting in it feels like torture. Maybe put a flat seat and foam padding under the mesh? Flexispot, you need to ensure the seat does not cause pain sitting in it if you are a larger person. My second gripe much smaller compared to the physical torture is I like to lean back without A.) Flipping completely to a lying down position, or B.) Be locked into to sitting upright or locked into leaning back without being able to sit upright again without first unlocking the seat back. Perhaps change the locking mechanism to how far back you can go but not restrict the seatback from coming up with you as you sit up again, if you wanna be extra make the locking the forward motion a separate lever. The chair doesn't have any padding; it relies on mesh to hold you, but maybe they should add some padding... The good: The chair was easy enough to assemble; my wife actually took care of it while I was away. The chair looked pretty nice, I don't care for gaudy looking gaming chairs, this looked like a nice cross between an office and gaming chair. the foot rest was OK, I couldn't really have it out while working, but if I wanted to lay back and just reflect and lay back it was nice. You do have to extend it while upright and your legs spread and the same to retract it. It rolled ok on my carpeted floors. Then again so has every other office chair I ever had. ... show more

Looks and Feels Premium, but Hurts My Back.
Color: Black Size: Overall Depth 44"
While the build quality of this chair feels high end and premium, it simply wasn't the right fit for me. I found it to be extremely uncomfortable, specifically due to the lumbar support part, which felt completely unnecessary and made it difficult to sit for long periods. Although the materials are nice, the ergonomics just didn't work for my needs. ... show more

Comfortable and easy to adjust
Color: Black Size: Overall Depth 44"
I’ve been using the FlexiSpot Ergo X for a while now and it’s been really comfortable. There are plenty of adjustments, so it took a little time to get everything set where I wanted it, but once I did it felt great. The mesh is breathable, the chair feels sturdy, and the lumbar support is probably my favorite part. Overall, I’m really happy with it for everyday desk use. ... show more
