Herman Miller Aeron (Size A, small)

Who it fits

People from about 5′0″ to 6′0″ tall. The seat goes from 14.75″ to 19″ high and is 16″ deep: the seat height and depth that range needs. It’s rated for 300 lb, so it suits people up to about 240 lb with the 25% headroom we look for.

Who should look elsewhere

• If you’re shorter than 5′0″: the seat is 16″ deep at its shortest, and at 4′11″ you need 15″ or less, so the edge presses behind your knees. Try the Herman Miller Embody, which fits from 4′9″.
• If you’re taller than 6′0″: the seat is 16″ deep at most, and at 6′1″ you want about 17.5″, so your thighs lose support. Try the Steelcase Leap Plus, which fits up to 6′8″.
• If you weigh more than about 240 lb, you want a higher weight rating. Try the Steelcase Leap Plus, rated for 500 lb.
