Office chairs rated for 300 lb or more (2026)

Each limit is the maker's own figure for the chair as listed. We don't show prices: they change often, so check the current price before you buy. "Not stated" means the maker's page doesn't say.

• If you want the most adjustments → the Sihoo B300 Pro. Sihoo states 330 lb and lists adjustable lumbar, a headrest, a sliding seat and 6D armrests.
• If you'd rather not adjust the lumbar yourself → the Hbada X7. Hbada says a motor moves the lumbar support as you shift; it also states 330 lb.
• If you want a padded executive look → the Nouhaus Posture, upholstered in PU leather, with five lumbar positions and a 330 lb limit.
• If you want mesh everywhere → the Nouhaus Ergo3D lists mesh across the headrest, backrest and seat; the Sihoo M57 lists a mesh seat and back. Both state 330 lb.
• If you want 6D armrests → the Sihoo B300 Pro or the Doro S300; the S300 limit is the lower 300 lb.

• Seat width. A weight limit says nothing about how wide the seat is. Each maker page lists seat dimensions; compare them with the chair you have now.
• Which figure the maker means. We quote the maximum user weight or maximum load as stated. Where a maker gives two different figures on one page (Sihoo's Doro S300 says 300 lb and 330 lb), we use the lower one; 300 lb still meets this list's bar.
• Gas lift and base. Several makers name the gas lift class or base material next to the weight limit. That is the maker's description; we don't add our own durability claims.

Branch states 275 lb for most of its chairs and 225 lb for the Daily Chair, and X-Chair's weight capacity loads by script on its pages, so we could not read it and show "Not stated". See every mesh-back chair or every fabric and leather chair; each result shows the stated limit. Related lists: mesh chairs with adjustable lumbar and a headrest and fabric and leather office chairs. The office chair buying guide covers weight limits and seat size.

We kept chairs whose maker states a maximum user weight of 300 lb or more for the configuration we list, quoted exactly. Eight of the chairs we show qualify; we picked six that cover mesh and padded backs and manual and automatic lumbar, and left out the Sihoo M18 and M56C, whose features overlap with the M57. Nothing here is ranked on price, ratings or popularity.
