Works great on my Formula racer chair purchased in 2016 (almost 7 years ago). Also purchased on a Friday morning, delivered on Monday.

As a guy who's spent a lot of time in front of a desk, putting in 8-14 hour days, I've gone through a few chairs that just didn’t hold up to the task. I’m a bigger guy, so I needed something that could really support me. I had heard about Dxracer's reputation, especially their Tank series, so I decided to dive in after doing a lot of research. And honestly, the hype is real. The chair was delivered quickly, the assembly process was smooth and felt solid, and the quality was evident from the start. The Tank series chair is a game-changer. Whether I’m sitting upright working, gaming, or even kicking back to relax, the support is spot on. I’ve already put in a couple of 14-hour days, and I feel way better than I did with my old chairs. The fully reclined position is comfortable enough to catch some sleep, and the magnetic pillow is crazy soft and plush. If you’re in front of a desk all day like me, this chair is definitely worth it.

Very comfortable! The cushions, especially in the lumbar area, also play a role. The cushion is very comfortable, not too soft or too hard. So far I have sat in it for 2 hours without any discomfort or pain in my lumbar or back.
