I don't think gamers particularly sit any different do they? I wouldn't say I'm a 'gamer' I just wanted a well made, solid, comfortable chair, being a bigger chap, cheaper ones aren't perhaps up to it.
The 'gaming chairs' around £140 where only to hold 120kg, which I'm over, so my £300 chair ticked that box and gave me a little reassurance that it was a solid.
I would disagree that gamers do not sit any different on two points:
1. you don't see an office worker with pedals, throttle and joystick
2. a PC gamer probably spends time seated working on a PC and gaming on a PC that could be a long time seated in the same chair compared to say a console gamer or non-gamer.
My view is this.. you have up until recently had 4 categories of chair for PC gamers:
1. Your 'run of the mill' Staples, PC World, B&Q office chair focusing on basic comfort and copying the look of executive office chairs for a low price point say £75.
2. You then have your benchmark seats where for a little extra you get more comfort, features, style etc i.e. the like of the Ikea Markus at £130
3. Commercial office worker chairs and executive seats £500 a shot.
4. Finally you have your Rolls-Royce ergonomic do everything seats for mega-bucks like your Steelcase's and Herman Miller's of the world around the 1k mark some more some less.
Now enter the market of "gaming chairs", for £200 - £500 you can have a great gaming chair suited to the needs of gamers right? Wrong what you have is the 'run of the mill' seat dressed and styled to a higher quality assuming you happen to like the idea of a racing car seat. All they have really done is added a bit more cushioning, arguably used some better components the rest is just looks.
What a "gaming chair" should be is something that builds on the smart ergonomics of the big boys and adapts them to the needs of gamers. Most importantly if you're going to charge £300+ for it that needs to be twice as good at being a "gaming chair" than an Ikea Markus. The only chairs that I have ever experienced that tick that box is the ergonomic ones because not only do they win design awards for their looks they also have useful features and adjustment for gamers not present on 'gaming chairs'..... and I shall grit my path with the salty tears of anyone who claims otherwise
either that or they need a good counter argument
