Perfect for work

by Amanda, Douglasville, GA, Apr 01, 2020

Our office bought these chairs for us a couple of years ago. My back no longer hurts after working long days. I find this to be the most comfortable chair I can recall ever having. I am on the shorter side, so when I prop my feet up to work, the fact that the lumbar support reclines with me is AWESOME! I am in the market for a chair at home, and all chairs are compared to this one. I am finding a hard time matching the comfort of this chair. I wish they weren't so expensive so I could have one at home too.

Decent, not amazing.

by Zeth, Pennsylvania, Dec 18, 2015

I work a job the requires me to sit for 10 hours a day, four days a week. I wanted a chair that was up for the challenge. This chair didn't seem very popular, but I was unable to find a "bad" review. After some long research sessions and taking into account the price and durability, I found myself always coming back to this chair.
Now I will say, the chair is built really well. Seems very durable and made with quality products. The recline feature is very very nice. Lumbar support is perfect. I find my back no longer hurts after sitting in it for a few hours like my old chair.

That's about where the good stuff ends I'm afraid.
I will say this now, if you are over six foot tall, go with the XT version.
I this chair is not very big, AT ALL.
I went with the normal version trying to save money and didn't think it would be that much of a difference looking at the specs, but either I was wrong, or this chair just wasn't worth it.
The bottom part of the chair is just too small in my opinion. There is about a six inch gap between where the chair ends and where my legs bend. I'm only 6'1.
I still notice my bottom starts to hurt after an hour or two of sitting, just like my old chair.
That was one thing I was trying to remedy with a high end chair purchase like this one, but at least my back no longer hurts.
Most people don't sit as long as I do, so this may not be a big problem for most.
That's pretty much it for the cons.

To summarize, the chair seems very durable and made with high quality material.
The recline feature is great and back support is wonderful.
The bottom seat needs some work for comfort.
If you're going to buy this chair, go with the XT version.
Overall I'm not very impressed as the bottom seat just doesn't work for me, and thus I'll be giving this 3 stars.
Remember this is just my opinion. Everyone's use of the chair will be different as well as the high and weight, so take this review with a grain of salt.
