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.

Very Comfortable Ergonomic Chair - Great for Long Work Days!
Color: Black, Color: Black
I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support. What I like: • Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain. • Good lumbar support and adjustable height/armrests. • Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable). • Smooth rolling wheels and sturdy base. • Easy to assemble (took about 20 minutes). The mesh back breathes well and doesn’t get hot. It looks professional in my home office too. Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it. Would I buy it again? Yes, definitely.

Great if you're average height.
Color: Black
Comfortable for the price. The seat could be a bit better, but for a budget friendly ergonomic chair, it's well made and has helped a lot with my back pain caused by my previous desk chair. Assembly wasn't terribly difficult, though I did have one screw with damaged threads. Luckily they ship spare screws in the kit, so that was a non-issue. Rollers work great on my small rug and hard flooring and don't tend to tangle cords or cables too much. Size wise, works great for my frame (5 ft 6 in) but for someone more than a few inches taller than myself, you should probably look at another chair.
