The chair is very comfortable, clean, no issues. Used for less than a month. Full control over all parts of the chair from top to bottom. You can come and try the chair and see for yourself. 1- The backrest can be raised up and down. 2- The armrests can be lowered and raised up, also back and forth. 3- The neck rest can go back and also forward. 4- The chair can be lowered and raised, and also reclined back and forth. Literally, full control over the chair as you like, Mashallah. #كرسي_مكتبي #كرسي_العاب
