It's a hit or miss sometimes when ordering furniture online, because much of your satisfaction with the product is going to be based on your personal experience with it, not technical specs. I was confident after doing a ton of research online both via reading reviews for this chair on Amazon, as well as watching video reviews on Youtube, and ultimately decided that this was the best office chair in this price range for me to invest in.Is it worth it to buy a new chair if your current chair still works? I had doubted the value of this investment as well for this very reason. However, I can now say with confidence that it was one of the best investments for my workspace, and that I should have purchased a new chair much sooner. It only took me 20 minutes to put this thing together, and it is SOLID.My favorite features:SEAT CUSHION - This new chair has a very supportive and comfortable seat cushion, which fixed the pain I was developing in my lower back and coccyx from my previous chair and its flatter, older seat.BACK SUPPORT - The built in lumbar support is making a huge difference in my posture, which goes on to affect my shoulders as well. It is often overlooked in office chairs, but trust me, it will save your back especially if you are at the desk for extended hours.NECK REST - I've seen a lot of people say that the neck rest in office chairs are not really comfortable or useful, but that is not the case with this chair. This chair offers an adjustable neck rest that is breathable and very nice to lay on, encouraging comfortable breaks throughout your work sessions.LEANING - With an adjustable tension for leaning back, this chair has been great to take breaks on between focused work sessions, or when you want to just sit back and watch a movie on your computer. I tend to keep the function locked when I am working so that I am always sitting upright without a tendency to slouch or lean back.ADJUSTABLE ARMRESTS - Understated feature in office chairs. Depending on what you are doing on your computer and how you are sitting, you will find that the adjustable height and positions of the arm rests give you so much more support you didn't think you need. Getting your arms supported properly throughout your work is going to make a huge difference on whether you will develop tight shoulders and neck.Conclusion: My hip, back, and neck tightness have all gone away since using this chair. I was a skeptic about whether it would actually contribute to alleviating all these issues, or whether I was just at my desk for too long, but it turns out this chair has saved my back and enabled me to work longer, more productive hours at my desk. If you are in the market for a new chair within this price range, this is it. Buy it, spend the 15-20mins putting it together, and you'll never look back. Totally worth it.
