Game-Changing Diagonal Sleep Space For Short Beds

Short-bed owners often have to choose: sleep with the tailgate down or unload the truck to make room. A diagonal truck-bed mattress creates a supported sleep zone while keeping useful space open for gear.

Key Features

Diagonal Sleep Length

Short-bed pickups often don’t have enough length for a straight mattress. CloudCore uses the truck bed’s longer diagonal to create up to 79.1 inches of usable sleeping length for solo campers. On compatible setups, you can stretch out with the tailgate closed instead of curling up or extending the bed.

Gear Space Beside You

A full-size mattress can take over the entire truck bed. CloudCore uses a single diagonal sleeping position, leaving room alongside the mattress for your cooler, packs, boots, cooking gear, and tools. Keep your gear in the bed instead of moving everything outside at night.

Foam & Air Comfort

Air provides adjustable support while the 4-inch foam core adds cushioning and stability. Compared with a basic air mattress, the hybrid construction helps reduce bounce and sag while still compressing for storage after the trip.

Built-In Pump

The pump is built into the mattress, so setup does not depend on finding and connecting a separate pump. Lay it down, inflate it, adjust the firmness, and get your sleeping space ready after a long drive, work shift, or day on the trail.

Roll-Up Storage

When it’s time to move, deflate and roll the mattress into the included storage bag. With a packed size of 28.3 × 13.4 inches, it stays ready for the next fishing trip, hunting weekend, work shift, or overnight stop without taking over the rest of your load.

What real owners are saying

Ali

2025 Toyota RAV4 XLE Owner

"Setup took two minutes, pump included, module charges over USB-C. Fit the RAV4 perfectly with no platform needed, and slept two of us by the lake like a real mattress."

David L.

2022 Toyota RAV4 Owner

"Took the whole family camping in the RAV4 for the first time. Kids were asleep before we finished making dinner, and nobody complained about the ground once."

Jordan M.

2023 Tesla Model Y Owner

"Fits the load floor perfectly, no gaps, no sliding. Woke up in the Sierras on Sunday feeling more rested than I expected from a car."

Mike B.

2020 Ford F-150 Owner

"Twelve hour shifts two hours from any job site. Now I lay the seats down, sleep in the truck, and I am back at it in the morning without the drive home."

Ingrid S.

2024 Model 3 Owner

"Drove through Jotunheimen after a week with no plans. The fit was exact, and the material held up through four nights without any issues."
