FlatCore Hybrid Support Mattress for Toyota RAV4
Vehicle-Specific Fit: Designed for the Toyota RAV4 cargo area.
Trunk-Leveling Support: Helps reduce rear-seat slope for a flatter car bed.
Foam Comfort: Stable cushioning for overnight car camping.
Fast Inflation: Inflates in 100 seconds and deflates in 115 seconds with a built-in 12V ABS air pump.
Compact Storage: Packs down for easier trunk and home storage.
Road Trip Ready: Ideal for SUV camping, EV camping, and weekend getaways.
Note: On all RAV4 Plug-in Hybrid models, the cargo floor sits slightly higher due to the battery placement, which may prevent the mattress from lying perfectly flat.

Real Mattress Feel
High-density foam adds the kind of steady support thin air pads cannot give. Less sag, less wobble, more sleep-after-the-drive comfort.
<2 min
Ready to Rest
The built-in pump gets the mattress ready in under two minutes, so setup still feels quick at camp.

Lie flat, even when your cargo floor doesn’t.

Hybrid support that feels more like a real bed.

Built-in pump. No outlet hunting.

Soft-touch TPU for nights inside the car.

Packs small, because gear space matters.

Open the hatch. You’re at basecamp.
