Where it makes sense
The current Comfort Deluxe Double is a deep, foam-filled mattress for adults sharing a car-camping bed. It deserves consideration when individual backpacking mats feel too narrow or too segmented, provided both sleepers accept sharing one firmness setting. Measure the bed footprint and the remaining usable tent space before buying. The manufacturer’s current page reports an ASTM R-value of 7.7; older versions and listings can carry different figures, so match the exact product generation rather than combining specifications. Its packed weight and roll size reinforce the intended role: comfortable vehicle transport takes priority over carrying the smallest possible sleep kit.
The tradeoff
A large, shared mattress with substantial packed weight; verify generation when matching retailer listings.
