I've been playing FPS game for a while, using Ikea solid wood tabletop with 2 alex drawer on each side, and a regular office chair, but i have been having pain on my right back muscle where I hold my mouse, I'm thinking it's the chair problem, so after a few months I bite the bullet and bought the HM Embody gaming chair.

Unfortunately that doesn't seems to fix my problem and seems to make it worse in some way, because I want good control on my mouse, I want my elbow to be slightly or same level of my desk on my sit up straight position, but that means I would have to put my chair near the highest height, and my footrest of 12cm are barely touching my feet, not really feel supported.

Then, my thigh and leg feel numb, because the embody chair seems to be softer on the back, and it cut off blood circulation for my entire thigh and leg, this impact my gaming performance by huge, always adjusting myself feels like something is off.

I'm 5'9" (175cm) and 219lbs (99kg), could this be my overweight problem (I'm trying to lose weight…) and my desk problem, i feel like the right desk height should be my current desk height ~75cm minus my footrest 12cm, so the ideal desk height for me is something around 63~65cm? i don't really see desk that are that low…

Anyone have solution to the issue?
