Unique Posh Operational Features:
PressureCast Foam: PressureCast foam cushions are used rather than cut foam to ensure seating comfort. Upholstery contours are retained during the life of the chair. Your chair lasts longer and feels better.
Lumbar Support: The scientifically engineered shape hugs and supports the back from lumbar to thorax.
Easy Ratchet Back: No handwheels to twist! This ratchet back is one of the simplest and ergonomically friendly ways to adjust lumbar height. Click it into eight positions over a generous 4" range.
Cast Aluminum Base: The cast aluminum base is stronger and more durable than comparable plastic bases and is easier to recycle.
