      Great chair, only one issue.
      Number of Items: 1
      As someone who is exactly 6ft tall, this chair is just about perfect for my height and body type. High quality materials, adjustable lumbar support, very ergonomic. Visually, it works well with my desk setup. It has already helped me improve my posture ten-fold. My only complaint might be that the tension on the recline joint is too much. Twisting it to the loosest setting doesn’t feel loose enough, you’ll need to put your feet up on something to recline comfortably and stay in that position. Other than that, great chair. I don’t see myself returning this one.

      Get this chair if it is on sale for $100 or less!
      Number of Items: 1
      I am a 180lb, 5'8" tall male. I needed an office chair that would support and cover my entire back, shoulders, and neck, while locking at 90° upright, and allow me to sit with my hips over knees (slightly) with my feet flat on the floor. I also needed the arms of the chair to support my arms and shoulders in a neutral resting position, as well as move up and out of the way. This chair did all of that for just over $100 and next day delivery. I'm happy with it and will be keeping it long term. Build time was 20 minutes. All needed tools and materials were included. Instructions were clear and easy to follow. Components appear to be properly made, well fitting, and durable. Everything works properly. The arms are the proper height for me. The seat cushion and lumbar curve are good. The wheels fit through doorways just enough. The seat height can be set both adequately low and high for my height and needs. The tilt sensitivity is adjustable via a knob under the seat. The position lock works properly in the upright position. The only cons for me: Position lock is not available in recline. The neck support is not padded enough and uncomfortable to rest your neck against for long. The neck support mechanism cannot extend closer to or further away from the back of your neck. It can only be moved higher or lower. The mechanism can also be tilted up or down to change its angle. This chair is worth the $100 I paid.

      Comfortable chair that works great for long hours
      Color: Black
      I’ve been using this office chair for a few days and it’s been very comfortable for working and longer desk sessions. The high back design and ergonomic support help maintain good posture, while the cushioning stays comfortable throughout the day. The chair feels sturdy and stable, and the 330 lb capacity gives it a solid, durable feel. It also rolls smoothly and quietly, which is nice when moving around the workspace without creating a lot of noise. Overall, it was easy to assemble, looks professional, and offers great value for the money.
