Getting into the $300 price range is where you'll find a lot of the greatest PC gaming chairs on the market, and the Ewin Champion Series Chair is easily one of the best on the cheaper end of the scale. It's got all the bells and whistles you're probably looking for in this price range.
It has great ergonomics with neck and back pillows, making it rather comfortable to sit in. It's fully adjustable so you can find the perfect spot for your back, neck, and more. However, it's known to need a bit of fiddling before the chair will feel just right.
