Ergonomic Office Chair with Slide Seat, Adjustable Lumbar Support and Headrest, Swivel Computer Desk Chair

Featuring a sliding seat that adjusts back and forth, this ergonomic office chair delivers a customized fit for users of different sizes. The seat itself is built with a 3.5-inch thick high-density sponge, about 17 percent thicker than standard cushions, for exceptional comfort during extended sitting. An S-shape backrest keeps the spine properly aligned, and the lumbar support adjusts up to 1.4 inches to match your body, easing strain on the lower back, shoulders, and neck, while the adjustable headrest helps prevent the head from tipping forward. A 90 to 130-degree rocking design and height adjustment suit a range of sitting needs, whether for focused work or a short break. Smooth casters allow easy movement without damaging tile, wood, or carpeted floors, and the armrests fold up at a 45-degree angle to save space under any desk. All hardware is included for an assembly time of about 30 minutes.
