The leather and metal seem to be of very good quality. My son bought this as his office/study chair. He is starting medical school and liked the professional look of this chair. He is 6’ tall and 200lb. There does not seem to be an issue with the chair rolling even with his weight. The chair is very ‘hard’ not that comfortable if you need to sit in it for long periods. Since my son needs to be staying awake to study, this will work for him as he won’t be able to get too comfortable and fall asleep.

Easy assembly and smooth movement

This chair has been a great addition to my home office. The assembly instructions are simple and easy to follow. The height adjusts smoothly, and the chair is very comfortable. I sit at my desk for about 9 hours a day, and this chair makes it easy to stay seated and work for long hours without discomfort. The cushioning and back support are solid. It spins well, and the wheels move smoothly. The build quality feels sturdy and reliable. Overall, a great value and a solid choice for anyone with a desk job. Highly recommend.

Stylish, Comfortable, and Great Quality

Color: Brown

I am absolutely in love with this chair! The brown leather looks very premium and fits my home office aesthetic perfectly. It was easy to assemble and feels very sturdy. The lumbar support is just right for long working hours, and the rocking feature is a nice bonus. Definitely worth the price!
