A hundred votes ahead of the its closest competitor, IKEA’s Markus chair is our landslide victor in the favorite affordable office chair co-op. Our readers love that it packs in many of the features you’d only find in more expensive chairs; like customizable height and tilt functions, breathable mesh back, built-in lumbar support, and pressure-sensitive brakes that keep in the chair in place when you stand up, and release when you sit down - not too shabby for under $200.
