Valve's long-anticipated Steam Controller is finally set to hit store shelves on Monday, priced at $99. As gamers prepare to experience the unique dual-trackpad design, accessory maker Mechanism is already poised to expand the controller's utility. Their innovative new product, the Basegrip, is the first accessory designed to attach the Steam Controller to a smartphone—and that's just the beginning.
What Is the Mechanism Basegrip?
The Basegrip is a clever mounting attachment that snaps onto the Steam Controller, instantly turning it into a modular gamepad compatible with a wide range of Mechanism's existing accessories. By using the Basegrip, you can connect the controller to a phone mount, a clip for the popular Ikea Skadis pegboard, or even a universal mounting system that lets you secure the controller to virtually any surface. Mechanism developed the Basegrip with early access to the Steam Controller's design, ensuring a perfect fit and seamless integration.

Phone Mount and Remote Play
One of the most exciting use cases for the Basegrip is pairing it with Mechanism's phone mount. Once attached, you can use the Steam Controller to play your PC games remotely via services like Steam Link or other streaming solutions. This transforms your smartphone into a portable gaming screen without sacrificing the tactile precision of a dedicated controller. Whether you're lounging on the couch or on the go, the combination offers a console-like experience that's hard to beat.
How It Works
Simply snap the Basegrip onto the back of your Steam Controller, then attach the phone mount to the grip. Adjust the clamp to hold your phone securely, and you're ready to game. The mount positions the screen comfortably above the controller, keeping the weight balanced for extended play sessions.
Mounting Options: Beyond the Phone
Mechanism's ecosystem doesn't stop with phones. The Basegrip is designed to work with a variety of their mounts, including one for the Ikea Skadis pegboard—a popular modular wall storage system. This allows you to hang your Steam Controller neatly on the wall, freeing up desk space and keeping your gear organized. But the flexibility goes even further: Mechanism's universal mount adapters let you attach the controller to tripods, monitor arms, or any standard 1/4-inch-20 thread (a common camera screw). This opens up possibilities for unique mounting configurations, such as attaching the controller to a tablet stand, a bed frame, or even a high-end racing sim rig.

DIY and Custom Uses
Because the Basegrip uses a standard Arca-Swiss compatible plate, it can also be used with numerous third-party photography and gadget mounts. Creative users have already started brainstorming ways to integrate the Steam Controller into their home setups, such as mounting it under a desk for VR gaming or securing it to a steering wheel frame for driving sims. The only limit is your imagination—and the strength of the mount.
Availability and Pricing
The Mechanism Basegrip for the Steam Controller will launch on the same day as the controller itself. While Mechanism has not yet announced the pricing for the Basegrip individually, their phone mount and pegboard mounts are typically sold separately. The entire system is designed to be modular, so you can purchase just the Basegrip if you already have existing Mechanism mounts, or pick up a bundle to get started. Check Mechanism's official website for the exact pricing on Monday.
Conclusion: A Smart Investment for Steam Controller Owners
The Basegrip is more than just a simple phone holder—it's a gateway to a modular ecosystem that significantly expands the Steam Controller's versatility. Whether you're a mobile gamer, a VR enthusiast, or someone who likes a tidy gaming space, this accessory offers practical solutions that are hard to find elsewhere. With its solid build, early access development, and compatibility with various mounts, the Basegrip is likely to become a must-have for early adopters of Valve's new gamepad.
