Ergonomic Mid-Back Mesh Office Chair – Lumbar Support, Flip Armrests, 250 lb Capacity

Ergonomic Mid-Back Mesh Office Chair – Lumbar Support, Flip Armrests, 250 lb Capacity

A mid-back office chair with a breathable mesh backrest, contoured lumbar support, and adjustable seat height. Built for extended desk use with a 90–120° rocking/recline mode to allow posture changes throughout the day.

Key Benefits

• Contoured lumbar support reduces lower back strain – The mid-back design follows the natural inward curve of the lumbar spine. By maintaining this curve during long sitting sessions, it reduces the tendency to slouch forward, which is a primary cause of lower back fatigue and discomfort during desk work.
• Breathable mesh back prevents heat buildup – Unlike solid foam or upholstered backrests, the open mesh structure allows air to circulate continuously behind your back. This reduces sweat and heat accumulation during extended use, which is a common complaint with padded chairs.
• High-resilience foam seat holds its shape over time – The seat cushion uses high-resilience foam, which is denser and more durable than standard foam. It resists the gradual compression and flattening that causes cheaper chairs to lose support after months of daily use.
• 90–120° recline with adjustable tension lets you shift posture – Staying in a fixed seated position for hours increases spinal load. The recline mechanism allows you to lean back and redistribute pressure, while the tension knob lets you set the resistance to match your body weight so the chair doesn't tip back unexpectedly.
• BIFMA-certified gas lift for safe height adjustment – The gas cylinder meets BIFMA (Business and Institutional Furniture Manufacturers Association) standards, which test for load capacity, durability, and safety under repeated use. This is a meaningful certification for office seating components.
• 360° silent swivel casters protect hard floors – The casters are designed to roll quietly and without scratching hardwood or tile surfaces, unlike standard plastic casters that can leave marks or make noise on hard floors.
• Flip armrests free up desk space when not needed – The armrests fold upward flat, allowing you to push the chair fully under a desk or work without armrest interference during tasks that require closer positioning.
• Built-in back pocket adds practical storage – A storage pocket on the rear of the backrest fits books, tablets, or small items, keeping your workspace clear without needing an additional organizer.
