Level Sleep Surface

FlatCore helps turn sloped folded seats into a level sleep surface, correcting vehicle-seat angles that can reach up to 12°.

7.5"

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.

80s

Ready to Rest

The built-in pump inflates FlatCore in 80 seconds. No loose pump. No slow setup. Just park, inflate, and rest.

Zero slope. Genuinely flat.

The Model Y cargo floor drops at an angle. FlatCore is contoured to cancel it out, foam shaped to the exact geometry of your car so what you're lying on is actually level.

Soft-touch TPU. No plastic smell.

The same material class used in technical outdoor gear. No off-gassing, no crinkle when you move, no stiff break-in. Pet safe, kid friendly, and built to feel good on the first night and every one after.

7.5 inches of recovery-ready foam.

High-elasticity foam that meets you where you land — post-hike, post-drive, post-everything. Thick enough to matter, supportive enough to mean it. The trail was worth it. So is the recovery.

Built-in pump. 80 seconds to inflate.

The pump is part of the mattress. No separate device, no hunting through gear in the dark. Turn it on, wait 80 seconds, done. Deflates in 90. The whole thing folds back into its bag and you're moving.

Packs down to gym bag size.

The whole setup compresses into its carry bag and disappears into the car. Frunk, cargo area, wherever your gear lands. There when you want it, completely out of the way when you don't.

The Model Y camp mode was built for this.

Woods, coast, wherever you end up. FlatCore turns the cargo area into a sleep space that's actually designed for the car.

Road Trip Essential

“Perfect for long road trips. It inflates quickly, fits my SUV well, and gives the kids a comfortable place to rest during stops.”

Great for Camping & Travel
