Now that my 2499 is repaired, I decided to address the VERY stiff mattress. I didn't want to replace it because it is a very good mattress, albeit a bit stiff. I did some research and while a lot of people like memory foam toppers for the mattress, there are some problems. The biggest is the fact that you are sleeping on a bed topped with petrochemicals (foam). Nothing natural about that at all. Particularly in the closed space of a TT, I don't want to be exposed to the off-gassing of foam. Actually, all the memory foam toppers tell you to let it air out for 48 hours before using it and even then there are many complaints about the noxious fumes.
I decided that natural fibers and hypo- allergenic polyester filling was going to work for me. Did a lot more research and found what I wanted, finally. Therapedic pillow top fiberbed mattress topper. Made in the USA of 400 thread count cotton with hypo-allergenic polyester fill and machine washable! The only one I could find with all those qualities! I could only find it available at Bed Bath and Beyond. Bought the Queen size because my 2499 has a full size queen not the standard RV queen. The photos show right after it came from the package. It was highly compressed in the packaging. If you buy one and change your mind about using it DON'T remove it from the package, you'll never get it back in once you break the seal and remove it.
Absolutely no odors and sheer heaven to lie on even before the bedding is added. I'll let you know how it does once I've used it some.
