What is its intended use?

Every user of Rooftop Tent Anyone who sleeps more than 5-6 nights a year should consider this mattress underlay. It becomes essential in humid camping situations (seaside, mountains, oceanic climates), during the shoulder seasons (spring and autumn when the temperature difference between inside and outside generates condensation), and for long overland trips where the mattress remains folded for weeks without ventilation. Without this accessory, the mattress will eventually become saturated with residual moisture and develop mold in the shell.

Installation and maintenance

Immediate setup: Open the tent, lift the mattress, and place the honeycomb underlay directly onto the tent shell (flat side down, honeycomb side against the mattress). Replace the mattress on top. No glue or fasteners required. For maintenance: Remove annually for cleaning with a damp sponge and mild soap, air dry, and reposition.
