Discover SnugNest
SnugNest fills the gap between your folded rear seats and cargo floor, giving your mattress a level surface to rest on.
Available for SUVs and pickup trucks.
"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."
"Most truck bed stuff I've tried needs cutting or shimming to fit right. This one didn't, it laid flat on the first try, held up through a full elk camp weekend."
"Did a solo loop through Zion and Bryce in October. The fit was exact and the material held up through four nights without any issues."
"Honestly didn't think a CR-V had enough room to make this work. Setup took maybe one minute and we had a real comfortable night's sleep."
Why Havnby?
Built for recovery. Not just camping
Rest Where the Day Takes You
Turn your vehicle into a real place to recover between drives, shifts, trail days, and long miles.
A Flat Surface for Better Sleep
Built to reduce slope, gaps, and pressure points, so your body can actually settle in and reset.
More Support Than an Air Mattress
Foam-backed comfort feels steadier, quieter, and more restorative than a basic inflatable pad.
Our Every Step
First Launch: Mattress 1.0
Introducing our first car mattress
Three foam panels, one removable cover, designed to fit Tesla vehicles and most SUVs. Simple, purposeful, and the start of everything.
Smarter Storage: Mattress 2.0
Nine pieces. Easier to pack, easier to carry.
The first version worked, it just didn't store well. Breaking it into nine modular pieces solved that without touching the comfort.
Roll-Compressed: Mattress 3.0
What if you could roll the whole thing up and go?
Two pieces, vacuum-compressed, ready in minutes. Unroll it and the foam comes back to full shape almost immediately.
Beyond the Mattress: First Electronics
We got curious about the rest of the car.
Our first in-car fridge was a bet on something bigger. Car living, not just car sleeping.
Air-Compressed Foam: Mattress 4.0
Real foam comfort. Small enough to actually travel with.
A built-in pump handles the compression. You unpack, inflate slightly, and the foam does the rest.
FlatCore Tech: Mattress 5.0
Folded rear seats are almost never flat. We solved it.
Adjustable air chambers in the base compensate for the slope. The surface sits level, and so does your sleep.
