Dually Extend
The Dually Extend expands the sleeping area of the Dually by maximizing extra space with HEST’s enhanced memory foam. The Extend easily attaches to HEST Dually models—Dually Extend 72 for the Dually Wide and Dually Extend 78 for the Dually Long or Queen—offering a larger mattress area suitable for slide-outs in campers, larger RTTs, and RVs. It can also be used alone on benches or other narrower spaces.

It fits perfectly in Tune Campers or Four Wheel Camper's Project M. The Dually Extend can also be used independently from the Dually, providing extra comfort for benches or other narrower spaces where HEST’s enhanced memory foam is desired.
