"We have the dually long mattress in our Four Wheel camper and always wished it was a bit bigger to fit that extra space. Thank you for making this!! We love our mattress and it will now be perfect. Thank you!"
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.

"Love it! I was looking for a solution that fit well in my Ursa Minor camper. Originally I was using two foamy 25" x 78" mattresses. The Ursa Minor is 50” wide in the shoulders but tapers and becomes more narrow towards the toes and I really had to squish it in there. I returned one 25" x 78" and substituted a duelly extend (20” x 78”). Those 5” of savings made a big difference and now the top closes nicely and I still have a wonderful HEST mattress to sleep on. The only thing that would make it better would be if HEST were to partner with Ursa Minor to make the mattress perfect. I’m unable to use the ursa minor hatch with this system which is the big compromise but the mattress is awesome!"
"These mattresses are incredible. Best night sleep ever."
