This is the second one of these I have bought for my office and I do like the slight alterations made to both seat and back that accomodate different staff needs

I recently purchased the Matrix Ergonomic Heavy Duty High Back Armchair in Black, and it has completely transformed my workspace. The comfort level is outstanding—supportive, sturdy, and designed to fit my posture perfectly. The high back and cushioned armrests give it a premium feel, and I can now sit for hours without any discomfort or fatigue. The build quality is excellent and gives off a strong, durable vibe that feels like it will last for years. This chair doesn’t just look professional, it performs like a dream. If comfort could win awards, this chair would be taking home gold.

I've been using this chair for about 2 years now and have enjoyed how it moves and shifts with you throughout the day as you shift in the chair, so it doesn't feel like you are sitting on something rigid and never feel discomfort. The adjustable arms offer great support, the mesh design on the back is both comfortable, promotes air flow and looks sleek in the home office. Smooth roller wheels, smooth spin, extremely comfortable seat. A really great chair. Can't recommend enough.
