This is my one-month review of the Anthros ergonomic chair, and honestly, it might be one of the best upgrades you can make for your desk setup if you care about posture and long-term comfort. The biggest reason is the way it promotes spinal alignment—something I don’t really see done this well on most “ergonomic” chairs. I went with the Office version in Onyx with the performance fabric (I don’t love how cold leather feels at first, especially in my basement), plus the armrests and the swivel five-spoke base for an all-black look with that natural oak accent. I break down the assembly (pretty straightforward, and the bottom piece is easy to remove with just two screws), then I get into the real star: the adjustable upper back support and pelvic support. Being able to dial those in together is my favorite part because you can actually set your posture instead of just hoping the chair fits you. I also like the tilt tension control (I keep it on the softest), the 16° tilt that keeps your lower leg height consistent, and the thick seat cushion with pressure-relieving cutouts that cradle your sit bones. It’s expensive (starts at $1,700), and you might feel some soreness at first while your posture adjusts, but with a 60-day money-back guarantee and 12-year warranty, I can see this being an endgame chair if you sit for long hours.
