Perfect chair with awesome back support. Assembly was super easy. Ignore the weird amount of dog hair in my house I have a husky and I can never escape it. The chair is very comfortable and holds both myself and my husbands backs very well. I’ve sat for hours with no hip pain. Plenty of cushion and honestly that’s what matters most to me. Adjustable arms and base are a major win. Rollers glide flawlessly on concrete floor!
