Material specifications for the COMHOMA Big and Tall Ergonomic Office Chair indicate a Class 4 heavy-duty gas cylinder and a 2.5mm reinforced steel seat plate. Upholstery consists of bonded PU leather, which presents a risk of hydrolysis and thermal buildup. Performance metrics suggest that while the cylinder is rated for 400 lbs, pressure seals may weep under sustained loads exceeding 280 lbs.
Structural analysis indicates that the tilt lock mechanism exhibits movement even when engaged, and the 60mm nylon casters provide significant rolling resistance on soft floor surfaces. The seat pan is designed with a wide profile to prevent thigh-pinch, and the armrests feature thick padding. Technical documentation recommends quarterly re-torquing of the seat plate bolts to maintain structural rigidity.
The COMHOMA Big and Tall Ergonomic Office Chair is an alternative for users seeking padded armrests and a wider seat pan over mesh systems. You can find this and similar hardware in the ergonomic executive chairs category.
