Swell Mattress - 54”W x 74”L

Designed for comfort on the road, the Swell Mattress uses layered gel foam construction to provide the perfect balance of support and softness. A firm base layer provides structure, while the medium-soft top layer cushions pressure points—making it comfortable for side sleepers without feeling the platform underneath.

Unlike traditional foam mattresses, the gel foam stays flexible in cold temperatures, so it won’t stiffen during colder adventures. The mattress requires no air or inflation—just set it in place and it’s ready to go.

Sized specifically for the Harker EDC, the Swell Mattress fits perfectly while still leaving enough space to store pillows and a blanket when the sleep platform is closed.
