SIHOO M18 Ergonomic Office Chair

The SIHOO M18 is the chair you buy when you need real ergonomic features but can't justify $400+. Adjustable lumbar support (height and depth), a 2D adjustable headrest, flip-up armrests, and full mesh construction make it feel like a chair twice its price. The 330 lb weight capacity handles larger users, and the S-shaped backrest follows the natural curve of your spine. At $200, it's the most-recommended budget ergonomic chair on Amazon with 16,000+ reviews. It won't last 12 years like a Herman Miller, but for the price of two nice dinners out, you get a legitimate ergonomic chair.
