Let's be honest, gaming chairs in all flavors of "enhancement" from vibration to sound to cup holders and beyond are quickly becoming a dime a dozen -- but the ButtKicker not only takes a different approach to vibration enhancement than other options but also wins the "most notable name" award in the arena. For one thing, it's not a chair -- it's a device you can install on any office chair to add vibration experience to not just gaming but anything producing sound on your computer including music and other media players. There are also two other versions of the device for use in home theater and auto installations (you can retrofit pretty much any old Lazy-boy in your living room). At $99 the gaming-focused version of the ButtKicker is cheaper than a lot of all-in-one gaming chair solutions as well. Oh, and how does the thing feel? Let's just say it tickled us in many nuanced ways.
