Fit For Royalty 

As Therm-a-Rest’s most luxurious sleeping pad, the MondoKing 3D is truly fit for car-camping royalty. Even side sleepers will wake up refreshed, thanks to the generously dense premium foam construction. The vertical sidewalls maximize sleep space so you don’t find yourself halfway off the pad in the middle of the night, and a high R-value means this will be your go-to all season. And because kings and queens don't blow up their own sleeping pads, the MondoKing self-inflates and quickly deflates when it’s time to break down camp.
