Quick verdict: Choose one double mattress when you want a shared surface and it fits the tent properly. Two individual pads offer more flexibility when partners prefer different firmness, camp separately or need to divide the load.

Measure the tent before choosing the bed
Tent capacity labels do not tell you whether a particular double mattress will fit comfortably. Measure the usable floor, including narrow ends, then compare the mattress’s inflated dimensions. Leave practical room for bags, shoes and access to the door rather than treating every centimeter as sleeping space.
EXPED’s Duo ranges come in different sizes, illustrating why double is not a standard width. Read the exact size selected in the listing. Product families can also change, so do not transfer dimensions from an older review to a current model with a similar name.
Think about two separate sleepers
A shared mattress makes sense if you both enjoy the same surface and want to avoid a gap down the middle. But it does not guarantee that movement, firmness or warmth will suit both people. Check whether the particular model has separate chambers or adjustments rather than assuming all double beds behave alike.
Individual pads let each partner choose thickness, firmness and insulation. They also make sense when one person camps alone sometimes. If you plan to connect them, check compatible straps and whether those straps are included; a narrow gap may still be part of the setup.
Packing and setup can change the value
Compare a double mattress with the combined weight and packed volume of two pads, including pumps or sacks. One large roll may be easy to place in a car but awkward to fit among other luggage. Two smaller rolls can be divided between bags or people.
Look at the complete inflation and deflation routine. A large comfortable bed is less appealing if packing it back into the vehicle becomes a struggle every morning. Confirm valve compatibility before buying a separate pump, and check the manufacturer’s instructions for storage between trips.
Buy for the trips you repeat
For couples who always car camp together, a double mattress can be a worthwhile comfort purchase if both people like it. Two pads are often the better starting point for mixed solo and shared use, differing sleep preferences or a smaller tent. Neither arrangement substitutes for suitable ground insulation.
Canadian shoppers should price the complete arrangement in CAD, including any connector, pump and fitted sheet. Check return conditions before opening bedding if you are uncertain about the fit. Keep serviceable single pads unless the shared surface solves a genuine annoyance; there is no need to replace two good beds merely to own one wider product.
