Just curious if anybody else has had problems with the air mattress that comes from the factory in the sleeper sofa? We purchased our BigHorn in March of last year, but only attempted to use the sleeper sofa for the first time 2 weeks ago. The mattress inflated just like it was supposed to, but after my son tried to sleep on it, it completely deflated. He ended up sleeping on the living room floor. I contacted Heartland last week and supplied pictures. They in turn contacted the supplier who told Heartland/us that it only had a 1 year warranty and it was out of warranty. When I asked the Heartland rep if Heartland would stand by the product, I was told no, and our only recourse was to purchase a replacement air mattress. It sure upsets me to spend as much money as we did for our new RV and have to replace the air mattress when it had never been inflated/slept on.
