One of the main pieces of advice given by physiotherapists and other chiropractors is to vary your positions (sitting, standing, etc.) and take at least one break every now and then. I know, it’s not the answer you wanted! But a reminder doesn’t hurt! Don’t forget to exercise between your gaming sessions, as many of the top names in French e-sports do. To answer your question: Yes, they’re perfectly suited to long hours of gaming or working sitting down. I wouldn’t say the same for lower-end models (for a whole host of reasons that would merit a full article)… But the top-of-the-range gaming chairs in this comparison are all suitable for long hours of sitting. And… Especially the 1st one, it surpasses absolutely everything at the moment.
