Learn how to quickly install a Universal Seat Back Mount in your Rivian R1T or R1S. This guide covers tools, steps, and common mistakes to avoid.

Quick Answer

Installing a Universal Seat Back Mount in your Rivian R1T or R1S takes about 10 minutes and requires no special tools. Just align the bracket, tighten the threaded stud, and attach your device mount.

Why Install a Seat Back Mount in Your Rivian?

The rear seats of the Rivian R1T and R1S lack built-in device holders for passengers. A Universal Seat Back Mount fills that gap, letting you attach tablets or phones for entertainment or navigation on long trips.

This stainless steel bracket uses a standard tripod stud, so it works with most tablet and phone mounts you already own. It's a simple, low-cost upgrade that makes rear-seat use much more practical.

Before You Start: What to Check

The mount is designed specifically for Rivian R1T and R1S front seat backs. Make sure your device mount has a standard 1/4-20 threaded hole to attach to the stud. The iPad and mount shown in product photos are for illustration only and are not included.

You'll also want to confirm the mount fits your tablet or phone securely. A loose mount can damage your device or the seat back.

Installation Steps

Step 1: Prepare the Seat Back: Fold the front seat forward to access the back panel. Locate the two pre-existing slots or attachment points on the seat back where the bracket will mount. Check that the seat is fully folded to avoid obstructing the bracket alignment.
Step 2: Position the Bracket: Align the stainless steel bracket over the slots so the threaded stud faces outward. The bracket should sit flush against the seat back without forcing it. If the bracket doesn't sit flush, double-check that you're using the correct slots for your Rivian model (R1T vs. R1S may differ slightly).
Step 3: Secure the Bracket: Insert the provided hardware through the bracket and into the seat back slots. Tighten firmly by hand or with a screwdriver until the bracket is snug. Do not overtighten. Overtightening can strip the threads or damage the seat back material. Stop when the bracket no longer shifts under light pressure.
Step 4: Attach Your Device Mount: Screw your tablet or phone mount onto the threaded stud. Hand-tighten until it's secure. Test the mount by gently pulling on it to confirm it won't come loose. Make sure your device mount has a standard 1/4-20 thread. If it doesn't, you'll need an adapter (not included).
Step 5: Test the Setup: Place your device in the mount and adjust the angle. Fold the front seat back to its normal position and check that the mount clears the seat cushion and doesn't interfere with driving. If the mount hits the seat cushion, try a different angle or reposition the bracket slightly before tightening fully.
