Mechanism, the company behind a "gaming pillow" for the Steam Deck and a growing list of grips for handheld consoles and PCs, already has its first Steam Controller accessory ready. Valve's new controller will be available to purchase on May 4, and that same day Mechanism will start selling the Basegrip for Steam Controller, an accessory that will let you attach the controller to a smartphone and plenty of other mounts the company already sells.
