High Back Ergonomic Office Chair with Adjustable Lumbar Support, Headrest and 2D Armrest, Computer Desk Chair

This ergonomic office chair pairs a high back mesh design with a thickened seat cushion for enhanced comfort during long work sessions. A high-density sponge seat measuring 3.5 inches thick offers about 17 percent more cushioning than standard chairs, while the breathable mesh cover helps keep you cool throughout the day. The S-shape backrest supports natural spine alignment, and the lumbar support adjusts up to 2.8 inches to fit different body types, easing pressure on the lower back, shoulders, and neck. An adjustable headrest helps prevent the head from tipping forward, and a 90 to 128-degree rocking function accommodates work, rest, or relaxation. Smooth-rolling casters protect flooring as the chair moves, and the armrests fold up at a 45-degree angle to tuck neatly under a desk. All hardware is included, so assembly takes roughly 30 minutes.
