Not the best. I’m only 5’10 but that is too tall for the headrest so had to take it off. The lumbar support is extremely aggressive. Had my box not gotten ruined in the rain I would have returned it.
I first tested a lot of desk chairs for a new office we set up in our Florida condo during the pandemic. This chair came out the top pick and I love it. Our granddaughter also liked it and often commandeered it for her school day then. It has a short seat and the mesh is very comfortable. The lumbar and headrest seemed right for me and the adjustments were intuitive and in nice small increments. I returned from pandemic lock-down to my regular home office and missed my FlexFit so I gave away my old leather chair and bought a second FlexFit. I still love it and would highly recommend this chair for short people who sit in a desk chair a lot. At the sale price the second one was also a great buy! Easy to put together; easier with two people. Solidly built.
