"Well constructed and fits the R1S perfectly. A nice upgrade from using a couple camping inflatable pads. Definitely recommend these for car camping. Got the pillows as well and cooling sheets / pillow covers. Perfect! I would prefer a smaller cut out for the arm rest which is larger than the space needed to accommodate stash pockets which are not needed. More mattress surface would be better than some extra pockets that are not needed."
"In combination with the Rivian in camping mode, two of these mattresses in the back made my last trip the most comfortable camping I have ever done. They fit very well in the Frunk, although it gets quite hot in there. So I wouldn't recommend storing them in there."
"Amazing mattress for Rivian . Almost made me want to replace my home mattress. Highly highly highly recommended"
"We slept well on the Foamy mattress in our Rivian R1S. The fit and quality are good."
"I was skeptical about finding a mattress that actually fits the Rivian R1S without weird gaps or discomfort, but HEST nailed it. The Foamy for R1S is perfectly sized for the back of my R1S and provides insane comfort for a foam pad. It packs up neatly, sets up in seconds, and completely transformed my weekend camping trips. No more shifting air mattresses or stiff backs in the morning—this thing feels like a real bed. Absolutely worth it!"
"Incredibly comfortable and perfect fit. Replaced an old air mattress and couldn't be happier with the upgrade. My favorite accessory I've purchased for my Rivian so far."
"Perfect fit in the R1S- love my set up in the R1S - as comfortable as my home bed. Easy to set up too!"
