Alexander ★★★★★ Oct 22, 2026

The clamp grips the seat hook so firmly there's zero wobble, even over bumps on the trail. I swapped the ball mount to my existing 17mm arm in under a minute and it's been rock solid for the kids' tablets on long drives.

Finally a mount that actually stays put on those Rivian seat hooks. The 17mm ball mount clicks into my existing arm perfectly, and my iPad is solid even on bumpy fire roads. Exactly what I needed for road trips.

Clamped this onto the hook behind my passenger seat and it holds my iPad Pro without any wobble, even on bumpy trails. The included 17mm ball mount paired perfectly with my existing arm, so setup took less than a minute. Finally, the kids can watch shows without me having to pass anything back.
