FlexiSpot OC3B

Who it fits

People from about 5′8″ to 6′0″ tall. The seat goes from 18.5″ to 22.5″ 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′8″: the seat only goes down to 18.5″, and at 5′7″ you need about 17″, so your feet won’t rest flat. Try the Sihoo M57, which fits from 5′6″.
• 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 Sihoo M57, which fits up to 6′7″.
• If you weigh more than about 240 lb, you want a higher weight rating. Try the Steelcase Series 1, rated for 400 lb.
