This chair has minimal adjustments Arms are fixed. It can raise/lower lock/recline and recline tension. Quick and easy to setup fairly sturdy for the price because of the minimal adjustments possible. I went to the store and sat in every chair this one fit my back/shoulders the best. Used in a home office for a week now with no issues. I like the lumbar curve no pillow needed and it doesn’t push my shoulders forward. I’m 5’10” 170lbs with an athletic build.
