The Rivian R1S is one of the most capable electric SUVs on the market, built for adventure with all-wheel drive, rugged off-road capability, and plenty of cargo space. But did you know it’s also an incredible vehicle for car camping? With the rear seats folded flat, the R1S transforms into a cozy, enclosed sleeping space—perfect for overnight stays in the backcountry or weekend road trips. However, the key to a good night’s sleep inside your Rivian is choosing the right mattress and pillow. That’s where HEST and Rivian come in. Designed specifically for the Rivian R1S, the HEST Foamy R1S mattress and the Rivian X HEST Camp Pillow deliver unmatched comfort, ensuring you wake up refreshed and ready for your next adventure.
The Rivian R1S offers a spacious sleeping area when the second and third-row seats are folded flat. Here are the key dimensions you need to know:
Cargo Area Length (Seats Folded Flat): ~74 inches (6'2")
Cargo Area Width:~49 inches (widest point), ~43 inches (narrower sections)
Cargo Height:~33 inches (plenty of headroom for sleeping)
This setup provides ample room for two people to sleep comfortably inside the vehicle. However, for the best sleep experience, you’ll need a mattress that fits the space while providing the right balance of support and portability.
The HEST Foamy R1S Mattress is specifically designed to match the dimensions of the R1S cargo area, ensuring a perfect fit. Here’s why it’s the best choice for sleeping inside your Rivian:
✅ Custom Fit for Rivian R1S– Unlike standard camping pads, the Foamy R1S is shaped to fit the contours of the R1S’s cargo space for a seamless sleeping setup.
✅ Link Two Mattresses Together for a Double Bed – Need more space? The Foamy R1S features built-in connectors that allow you to link two Foamy mattresses side by side, creating a full-width sleeping area for two people. No gaps, no shifting—just premium comfort. Sold separately, just purchase two.
✅ Premium Memory Foam Comfort – Made with two layers of high-performance memory foam, this mattress offers superior pressure relief and support, making it far more comfortable than inflatable pads.
✅ Portable & Easy to Store – The mattress rolls up for easy storage, so it won’t take up unnecessary space when not in use.
✅ All-Season Ready– With optimal insulation and airflow, the Foamy R1S provides comfort in warm and cold conditions, ensuring a great night’s sleep no matter the season.
✅ Durable & Easy to Clean – The removable, machine-washable cover makes maintenance a breeze after long adventures.
