A gaming chair will be bad quality and uncomfortable for MOST people.

Your best bet will be a high-end adjustable office chair, such as Herman Miller. These chairs are very expensive, but consider how much you're sitting (easily 8h+ a day if you work from home and are a gamer) and the amazing warranty (12 years+). I stopped trying to save money on chairs and mattresses and all my little pains went away.

However, to make the most of it you have to try them to find the best one for your body. A good store will help you find the best chair for you and adjust it to fit you perfectly.

Thanks for all your extra comments! I started playing 2k in the meantime, got the nba app and started watching highlights. Lots of fun.

Also great training tips
