This is literally the best office chair I've ever had! It is a STEELCASE THINK adjustable office chair (in black + dark gray) with all the upgrades ✅  Mesh back ✅   Adjustable lumbar support ✅   4-way adjustable arms But my FAVORITE thing about it is that it is one of the most sustainable office chairs in the market. 🍃 💗 It retails for about $800 once you add all the upgrades and although this one is not new, the condition is EXCELLENT. It barely has any wear and tear signs. 🙌🏿  No visible scratches 🙌🏿  the fabric is in perfect condition 🙌🏿  A top-notch quality chair that will last you for a long, long time. "But if it's THAT good, then why are you selling it?", you may wonder... 🤔 Well, my virtual friend, I originally bought one of these as a recommendation from my PT to ease my shoulder/neck pain with better lumbar support and posture ... it improved my work-from-home experience so much that I got one for my partner as well... and we have been in LOVE ever since. I feel like I'm working at a fancy startup and not in my home! Now we've decided to add a stand-up desk to our office arrangement, so we need to upgrade one of the chairs to the stool version. This is really just a long way for me to say: you're in luck! Thanks to my standup desk, your search for an amazing office chair is over. Feel free to message me with any questions ✨
