Designed for Rivian R1T and R1S second-row seating, this seat back anchor mount offers a secure and versatile solution for holding phones and tablets. It utilizes a 1/4-inch screw mount system, making it compatible with a wide range of devices including MagSafe accessories and standard phone cases. The mount features a 360-degree adjustable head, allowing passengers to find their preferred viewing angle for video calls, navigation, or entertainment. Its construction focuses on stability and ease of use, ensuring minimal movement even on rough roads.

The main body is constructed from a combination of reinforced plastic and metal components, giving it a solid feel without adding excessive weight. The clamping mechanism is designed to hold devices securely, with padded contact points that prevent scratches and vibrations. The 1/4-inch screw anchor connects directly to the seat back structure, providing a stable foundation that remains firmly in place during daily commutes or longer trips. The overall build quality emphasizes durability, with tight tolerances that reduce rattling and wear over time.

Installation is straightforward with no additional tools required for most setups; the screw mount screws into the pre-existing anchor points in the vehicle’s second row. Once attached, the clamp can be adjusted to accommodate phones from compact models to larger phablets, as well as tablets up to a certain size. The 360-degree rotation and tilt allow users to switch between portrait and landscape orientations easily. This flexibility makes it suitable for backseat passengers who need hands-free access to their devices for work, study, or relaxation.

In practical use, the mount maintains a stable grip on devices, even during sudden stops or sharp turns. The tension in the clamp is sufficient to hold heavier tablets without sagging, and the screw mount prevents the entire unit from shifting. Its compact footprint does not obstruct the view from the rear seats, and the matte finish resists fingerprints and smudges. The overall design prioritizes functionality, with a clean aesthetic that blends with the vehicle interior.

At a competitive price point, this phone and tablet holder delivers a high level of utility for Rivian owners seeking a reliable backseat mounting solution. The combination of adjustable positioning, sturdy construction, and easy installation makes it a practical accessory for families, ride-share drivers, or anyone who frequently has rear-seat passengers. Its thoughtful engineering ensures long-lasting performance without unnecessary complexity.
