Review on Upgraded Ergonomic Office Chair: Lumbar Support, Adjustable Armrests & Headrest, Mesh High Back, Home Office Desk Chair, Computer Chair, Rolling Chair by Jenn Arnold

What a terrible chair design. I have a really hard time believing these are real reviews. The lumbar support protrudes unnaturally, leaving a 4 inch gap between your back and the chair when you try to sit up straight. It fully arches the spine and the abdomen sticks out. The only comfortable way to sit is lying on your back, which completely defeats the purpose of an office chair. 5 feet 9 inches. She tried and couldn't find a way to sit comfortably in it. It's also about 3 inches smaller. I can even donate this item.
