There are more than 20 different gaming chairs posted (with links to even more), ranging in price from $37 to $369. It all depends on what your husband is looking for in the game-chair "experience." Just click on any chair for more extensive design specs & features, including system compatibility, color options, etc.

My son received this one as a gift last year:

It’s on sale in stores for $37 until Saturday (12/8) — I saw them at two different Southern California Target stores toDAY!

Note: This particular chair and the other basic models are built for a young person’s dimensions, so it wouldn’t necessarily be a good choice for your husband unless his height & weight are close to his high school frame-size.

Happy hunting!
