Our Verdict
Pick the SIHOO M57 if you want a lumbar that moves in both height and depth, with SGS certification on top of BIFMA. Pick the CAPOT if you would rather have 4D flip-up arms, a 5-year warranty and a 400 lb rating.
Pick the SIHOO M57 Ergonomic Mesh Office Chair if
- The lumbar adjusts in both height and depth.
- The listing names SGS as well as BIFMA.
Pick the CAPOT Ergonomic Mesh Office Chair if
- Four arm adjustments come with a flip-up design.
- A 5-year warranty is stated, with notes that describe a free parts program.
- The listing gives a 400 lb capacity.
Key Differences
- Lumbar: the M57 adjusts in height and depth, while the CAPOT states a height adjustment and does not state a depth control.
- Arms: the CAPOT lists 4D flip-up arms and the M57 lists 3D arms.
- Warranty: 5 years on the CAPOT, 3 years on the M57.
- Owner feedback: 8,093 reviews sit behind the M57 and 1,366 behind the CAPOT, both at 4.3.
- Base: the M57 is aluminum and the CAPOT is steel.
