I'm fat (120 kg, 190 cm) and so have an ergonomic chair made of fabric (forgot brand)
I really do not sit much but I want to gamble longer but my chair is hell.
The funny thing is when I do something else on the PC for hours then my po does not hurt, maybe just a little bit but when I start to gamble something it hurts like 30 minutes later as if I'm out of the sky on my but land on the ground. I'm not a pro or so, I'm interested in indie, RPG and Minecraft and so if my backside hurts right then I do not feel like playing and make the game out.
What chair can you recommend me with which you can sit for more than 10 hours without problems? I also have a bit of spinal problems and stuff. I would pick a Noblechairs Epic. The is expensive but the reviews are great.
Possibly, a diet change in conjunction with sports would be just as helpful. Your body has already spoken up, as you write. You should listen to him.
How about when you get away from the PC instead of gambling? You'll look back on this time later in life and realize how hard you were wasting your time, and I'm not talking about gambling but your real life.
The reviews of the gaming chairs are all faked. You need a chair of at least 120kg or better you save the chair and go often for a walk.
