AF528 - Office Master Affirm Executive High Back Ergonomic Chair

Office Master AF528 is an executive High Back Chair shown in Night Fall Black Mesh, JR-69 arms, standard polished aluminum package, and dual color soft casters (additional charges may apply). Affirm’s modern, sleek, frameless mesh design evinces the confidence to fit in to any workspace - whether a tech start-up, a healthcare environment, an educational facility, an architectural firm or a more traditional office place it’s the perfect combination of class and comfort. One of the salient features of this chair is its synchronous tilt mechanism. This mechanism reduces the seat rise when you lean back in the chair. This means, that when the back is reclined 2 inches, the seat is raised by only 1 inch. This gives a 2:1 back to seat ratio. So with the synchronous tilt mechanism, the movement of the backrest is larger than the movement of the seat. With the standard swivel-tilt mechanism, the back and the seat are fixed together, so when you lean back the seat is raised at the same rate the back is being reclined. When this happens, the back is reclined 2 inches, and the seat is raised 2 inches. This give a 1:1 back to seat ratio.Features: Executive high back Pneumatic lift EZ back height adjustment 5-stage locking tilt Synchronous seat/back tilt “Frameless” mesh back design Seat depth adjustment Dual-tone universal soft casters Independent back tilt Side-mounted tension knob Nightfall black mesh is default Specifications: Model/Sku Office Master AF528 Overall Width 27" Overall Height 41.5-49" Back 21"w x 24"h Seat 20.5"w x 17.5-20"d Seat Height 17-22" Carton Weight 58 pounds Warranty 12 year limited Chair measurements are approximate and are based on switching cylinder heights on otherwise the same chair, with the same base and casters.
