Make long drives, overnight road trips, and outdoor adventures more comfortable without bulky gear. This rear seat extension plate fills the gap between front and back seats, creating a stable platform that integrates with ONTYZZ air mattresses.

How will this extension plate improve sleep on long trips?

The extension plate levels and supports the air mattress where the vehicle normally has uneven space, reducing pressure points and sagging. Its firm, foldable structure keeps the mattress steady so you can rest or nap safely while parked. Mesh sides help prevent items from rolling into the footwell, preserving a consistent surface across the backseat area.

• Compatible: Designed to work with ONTYZZ backseat air mattresses
• Stability: High‑quality webbing and buckles secure the plate in place
• Comfort: Mesh side panels maintain edge support and ventilation

What features make it easy to store and carry?

The plate folds down to a compact size and includes a built-in carry handle for quick transport between the car and your campsite. A PE flat pocket approximately 55 × 37 cm keeps the unit protected when not in use, reducing trunk clutter. Lightweight construction and the integrated handle simplify loading and unloading.

Will this fit my car and how is it installed?

The ONTYZZ extension plate is sized to suit most standard passenger vehicles but is not recommended for cars with sports seats. Installation is straightforward: unfold the plate, position it between the front and rear seats, and secure with the provided webbing and buckles. The plate’s shape and height are engineered to create an even sleeping plane when used with a compatible air mattress.

How does this accessory help keep my car tidy?

Beyond providing a sleep platform, the extension plate helps organize the backseat area. Mesh side pockets and the included storage bag give dedicated places for phones, chargers, and small travel gear, reducing loose items that would otherwise clutter the cabin. The foldable unit itself stows away compactly when not in use.

• Integrated mesh pockets prevent small items from shifting
• Dedicated storage bag holds the plate when folded
