ADD: FS 360 Armrests

Better Support! More Flexibility!  The FS 360 Armrests change the game in office seating ergonomics. When used correctly, armrests provide muscular support to prevent shoulder and neck strain while sitting for long periods. No two people sit or move the same way in an office chair. Therefore it is essential to have armrests that are just as mobile and versatile.

The FS 360 Armrest arm pad is designed to rotate 360 degrees and slide forward and backward. FS 360 Armrests are designed to support users across any work setup. Whether working at a desk, reclined back in the chair, leaning to the side, or using a phone, FS 360 Armrests will rotate and move to provide ideal support. FS 360 page.

X4 Chair Customer Reviews

Overall very comfortable and seems to be well constructed. Only two things I would change. The head rest adjusts up and down but not back to front. And the seat a just a little too firm.
Review by MDG - Posted on 8/29/20

I've had my X4 for a couple days and so far, I really like it. I'm 6'4" tall and the ability to raise the chair height and back height to a comfortable level is going to be a game-changer in my comfort. The taller piston has been great (it's an accessory option). Huge thank you to Nate in Customer Service. My chair arrived with some damage and he was on the phone to me within minutes of when I sent an email to report it. He also checked-in with me several times to make sure everything was good.
Review by Mark - Posted on 8/24/20

Great Service From Beginning to End.
Easy Assembly.
Superior Quality.
Most Comfortable and Most Adjustable Desk Chair I have ever owned.
Review by Craig - Posted on 8/21/20

The new chair solved a big problem. In my old chair I was no longer able to sit at my desk for more than~20 minutes. The X-chair 4 has the perfect adjustments to solve my back fatigue issues. With the new chair just a couple of days old I have spent hours at a time working at my desk without pain. I must say I also had great help from my X-Chair support person - Max B. Max B started by answering all my live chat questions and then my direct calls to him. Max B made it easy and fun to purchase the X4. We had a few laughs along the way as Max B has a sense of humor. When I finally ordered - the chair should up the next day - it took less then five minutes to put together. After the chair was assembled, I called Max B on a small adjustment issue while I was kicking back enjoying the new chair. Overall I had a great experience that I am happy to share with others.

This is our first X Chair. Glenn Beck made an excellent suggestion in advertising your products. It was delivered sooner that advertised. It was very easy to assemble and is a very comfortable chair and is a great assist to my posture and aching back. We will be ordering more chairs from you in the future.
Review by iChristar - Posted on 1/6/20

Fantastic chair. We requested the blade wheels as well. The chair glides across the floor incredibly smoothly. We have wood floors and the wheels do not make any marks on the floor. We like the way the chair reclines. Very comfortable and well made. The follow up service is fantastic. No issues whatsoever.
Review by RAC Comfort - Posted on 12/23/19

I really love this chair. The adjustment capability insures a perfect fit. I assembled my own and found it very easy to do. Perhaps one of the very best features is how well designed it is. It is compact and very maneuverable, working well between a desk and console. All the surfaces are firmly supported but not bulky in any way, The 5 wheel base is very stable but compact enough not to get in the way of feet or furniture.
There is a special thrill in an all around well engineered piece of equipment.
Review by Steve P - Posted on 11/27/19

I love everything about this chair except the armrest adjustment. It needs to have locks on both the height and the swing adjustment. The forward and backward adjustment is good because it stays where you put it.
Review by Joe - Posted on 11/7/19

Very good chair in almost every way. My only complaint after a few weeks is that the lumbar support section is very aggressive. I wish it was either adjustable, or less invasive. I am very aware of it when I am using the chair, more than I care to be. If this was in a lineup of chairs in a store, it would have prevented me from buying it.
Review by BVF - Posted on 10/14/19

Great chair great service. a can now sit all day at my desk if needed
