FAQ

Is the Aeron or Leap better for long hours?
Both are all-day chairs. Aeron cools better for hot sitters because of full mesh; Leap’s foam and LiveBack dials often feel more ‘supported’ for people who dislike mesh pressure patterns.
Which is cheaper refurbished?
Leap V2 typically lands lower on the certified-refurb market than a Remastered Aeron in comparable condition, though Classic Aerons can compete on price.
