MAYEERTY Office Chair with Flip-Up Armrests Space-Saving Design Fits Under Desk

This ergonomic high-back office chair is designed to fit the natural curve of the human spine, with built-in lumbar support to effectively relieve back pressure. It features a 3.94-inch thick high-elasticity sponge concave seat cushion that resists deformation and delivers all-day comfortable support. The breathable mesh backrest enhances air circulation to prevent sweating during long hours of sitting. Equipped with flip-up armrests, they can be raised or lowered to meet different needs. Flipping the armrests up allows the chair to be tucked fully under the desk for space-saving storage, while the wide armrests offer soft, stable support for your arms and hands. The chair supports pneumatic height adjustment from 19.5" to 22.23" to suit different body heights, and a 90–120° reclining function for customized sitting positions during work or rest. A sturdy five-star base and high-quality gas lift ensure strong stability and durability, with a maximum weight capacity of 275 lbs. 360° swivel casters move smoothly and quietly across floors without scratching surfaces. The chair includes all hardware and tools for easy assembly, which can be completed in about 15 minutes. Professional customer service is available to respond and assist within 24 hours for any questions.
