BestEvMod Seat Back Second Row Phone & Tablet Holder - Rivian Fit

In this review of the BestEvMod Seat Back Second Row Anchor, the bottom line is simple: this is the best fitted backseat phone and tablet mount for 2022-2026 Rivian R1T and R1S owners who want a secure, OEM-looking solution. Designed from a 3D laser scan of the Rivian second-row seat back, it installs with included screws and gives passengers easy access to phones and tablets while keeping devices stable on long drives. The reviewer found the build quality and fit to be the strongest selling points, with a few minor installation quirks to note.

Key Features

• Perfect fit: The mount is modeled from a 3D laser scan to match the Rivian R1T and R1S second-row seat back for a seamless, factory appearance and secure attachment.
• High-quality material: Injection-molded ABS construction makes the anchor sturdy, wear-resistant, and easy to clean after frequent use.
• Universal device support: The design holds all phones and Android devices and supports tablets, so backseat passengers can use a wide range of screens comfortably.
• Adjustable positioning: A 17mm rotatable ball head provides 360 degree adjustment to set viewing angle for every passenger and device orientation.
• Accessory-ready: The built-in 1/4' female thread accepts cameras, GPS units, or other accessories for additional flexibility beyond phones and tablets.
• Included hardware: Screws are supplied and the package provides everything needed to install the anchor following the product image instructions.

Who It's For

The BestEvMod seat back anchor is aimed at Rivian R1T and R1S owners who want a permanent, well-fitting solution to hold phones and tablets in the second row. It is especially useful for families and frequent passengers who want a hands-free, stable viewing experience on long drives.

People who prefer a removable, clamp-style mount or who drive a vehicle other than the 2022-2026 Rivian R1T/R1S should look elsewhere, since this product is specifically designed to match the Rivian seat back and is intended as a semi-permanent installation.

Pros & Cons

Pros

Cons
