Office chair, the chair is in good condition and has nothing wrong with it. It has been with me for about 5 months. The armrests raise upwards at a 90-degree angle. The back does not recline backward, and this is its flaw that I did not like, and for this reason I decided to sell it. The neck or headrest raises and lowers to the extent that suits you. The chair can be lowered and raised, and it is comfortable, honestly.
