Mid Back LeatherPlus Guest Chair

The B7309 is a mid back guest chair upholstered in black LeatherPlus, a blend of leather and polyurethane designed for softness and durability. It has a fixed cantilever base without casters and sturdy polypropylene arms. The chair supports a weight capacity of 275 lb and offers lumbar support with extra-thick cushions.

Cantilever base without tilt or height adjustment

Because the chair lacks pneumatic gas lift, tilt tension, knee tilt, infinite lock, upright lock, back adjustment and seat slider, the sitting posture remains fixed. The cantilever frame provides a gentle flex under sustained load rather than a rolling or reclining motion. Arm height is fixed at 25.5 inches from the floor.

Matches B7301 high back

This guest chair shares the same black LeatherPlus upholstery as the B7301 and B7306 models for a consistent look across a reception or conference area. It replaces standalone visitor seating that does not coordinate with executive furniture. The jump is worth it when a unified aesthetic and matching arm height of 25.5 inches are required.

Questions about this item

Does the cantilever base flex or creak when someone sits in the B7309 for a full workday?

The black cantilever base is a fixed steel frame with no moving parts, so it does not flex or creak under the 275 lb capacity during extended use.

What additional parts or tools are required to start using the B7309 guest chair?

Nothing — the chair ships fully assembled with no casters, gas lift or adjustment mechanisms to install.

Will the black LeatherPlus upholstery on the B7309 match the B7301 high-back and B7306 mid-back executive chairs I already own?

Yes, all three models use the same black LeatherPlus material, so the guest chair will match the executive chairs exactly.
