Is a mesh task chair worth it under $300?

Reviewers we read generally agree that mid-range mesh chairs in the $150–$300 band offer meaningful ergonomic upgrades over basic task chairs, particularly on breathability and adjustable lumbar. However, specialist subreddit threads repeatedly caution that build quality, mesh tension longevity, and lumbar geometry vary widely, and that no chair in this range will match a used Steelcase Leap or Herman Miller Aeron for long-term durability.
