I just bought this chair today after sitting on all the chairs in the store. This one addressed all my aches and pains of sitting. Lumbar is great and the head rest is defiantly a plus for long hours of working from home. This was the easiest chair I have ever put together. Packaged well and very easy to understand the directions. This a an A+++ in my book. I could fall asleep in the chair. Perfect for my needs and fits my frame perfect. 5' 6" tall if one is taller the head rest might fit differently. I will not need my butt pillow or my back pillow with this chair. It feels like I am floating. I hope the mesh survives the 5+ years as I did not spend the extra 19.00 for the insurance. I believe it will. This is a MUST buy if you work at your desk for long hours. I will update after a full 8 hours of working.
DO NOT BUY. THE MESH SEATING WILL SAG AND IT CAUSED ME BACK PAIN. LOT of people reported the same issue with this chair. You can find them in the reviews section. I bought my first Hyken Mesh Chair on August 2019 from Staples in Springfield PA. Few weeks after using this chair the mesh seat started sagging and I started having SEVERE LOWER BACK PAIN. I called Staples and they offered to send me this replacement chair since it was under warranty. I requested them for a store credit since I am afraid that the same replacement chair might make my back pain worse. But they were not able to help me out. I still haven't opened the replacement chair they send me. As a long term Staples customer I was disappointed in Staples. I bought a Staples brand chair that caused me back pain. After contacting Staples multiple times via chat in store and via phone didn't help me to get a store credit to buy a different chair.
I did a lot of research and wanted to find a comfortable yet supportive chair as I sit most days over 10 hours. The Staples agent Dominico was very helpful when we went into the store and was spot on recommending this chair. I have used it for a week now and my back pain is gone. I would highly recommend this chair. Don't rule it out due to it being mesh and not very wide. The supportive sides are amazing.
