Structural analysis of the COLAMY High Back indicates a chassis utilizing high-density molded foam and a Class 4 SGS-certified gas cylinder. The tilt mechanism consists of a multi-function frog-style plate designed for synchronized reclining. Material specifications show the use of K+R style mesh tensioning for the backrest and a heavy-duty nylon base rated for a 300 lb static load.
Performance data confirms the inclusion of 3D adjustable armrests for ergonomic versatility. Hardware limitations include plastic caster wheels and a fixed lumbar depth. Technical maintenance requirements include re-tightening the bolts every six months, as the factory-applied thread locker may be insufficient for sustained recline usage.
The COLAMY High Back Ergonomic Office Chair - Black is a high-load alternative for users requiring Class 4 cylinder stability and 3D armrest modulation. For comparative data on professional seating, visit the ergonomic executive chairs section.
