I spend a lot of time sitting due to the fact that I often work at a computer, so lately I started to experience a lot of back and lower back pain. Looking for a solution to this problem, I decided to buy myself a new, more comfortable chair and came across the website https://corechair.com/explorin....g-office-chair-alter I bought their chair and do not regret it one bit. After all, thanks to it I not only stopped experiencing back pain, but also slightly improved my posture, with which I also had problems. So I advise everyone this chair, your back will thank you.
