Back Height Lock Instructions

X3 Customer Reviews

I have lower back issues, as I am sure many people who work infront of a desk for 8 hours a day do. With the latest pandemic I was forced to work from home. With only a dinning room chair and a cushion I was miserable, I couldn't sit still for too long, thus I was not productive at work. I researched like crazy, went to a Back store, tried out their chairs and with 1 minute in the xchair3, I fell in love. It conformed to my back and gave me support where I needed it. I don't have to constantly adjust the lumbar, it just adjusts to me. My lower back doesn't bother me as much, and I'm working for longer periods of time. Needless to say, although this was the most expensive chair in the whole house, it was worth it. Thank you xChair.
Review by Jon - Posted on 5/5/20

I purchased this chair on the recommendation of the owner who I have known for 20+ years and who I consider very knowledgeable in this space. The reason I needed a chair was that like many Americans I was facing several months working from home and my current equipment was causing me back pain.
I have been using my X3 from Xchair for the last week and cannot say enough good things about it. If you are concerned about buying an expensive chair without sitting in it and fearful of putting it together, you can relax, as the chair is easy to put together and incredibly adjustable and comfortable.
1) Putting the chair together was easy. I am not handy at all, and using the video on the website I easily completed in less than 30 minutes.
2) Highly adjustable. The best features for me are the unique lumbar support and the headrest.
I cannot say enough good things about this chair, which is more comfortable than my chair in the office.
Review by Missouri Xchair lover - Posted on 5/4/20

Hearing/Reading X-Chair ads for months made me curious. Working in uncomfortable office/conference chairs for 35 years made me ready. Mandatory work from home for four weeks in an equally uncomfortable office chair made me a buyer. Using my new X-Chair for the past week made me a believer and fan. Thank you!

Review by The Wonderdog - Posted on 2/10/20

Really great comfort, adjust-ability, and top quality for a long lasting durable product. Have one in our control room (24/7 operation). Everyone loves it to much it is the go to chair. I loved is so much I had to get my wife one for our home office.
Review by MurDog - Posted on 2/1/20

I was able to assemble my new X3 chair in about 20-30 minutes. What a delightful surprise that was. It is very comfortable, making me wonder why I waited so long to change.
Review by Dave - Posted on 1/20/20

Amazing chair, easy to assemble, great instructions and online tutorials to adjust to perfection. My wife wanted me to check this chair out and I blew off the idea of a new chair until my old one broke. Now I am glad that it did!
Review by Dave - Posted on 12/28/19

This is a very nice and comfortable chair. I love the adjustability of it.

Just got this chair today. The chair was easy to put together, and I absolutely love it! My posture has changed, and my back feels much better.

Shipping was super fast as well. I would not just recommend the chair, but also Special Needs Computers. I'll be back for more :-)
