Brooklyn Bedding has really become popular. Made in U.S.A. You can peruse them online. But, if you decide to buy from them check out one of the YouTube videos from RV Miles, Endless RVing, Changing Lanes, and maybe more because their videos are sponsored by Brooklyn and they offer discount codes savings up to 30% (Endless RVing)
I do not have a Brooklyn Bedding Mattress. I was not aware of them yet when my wife and I went to a local Extreme Mattress Store (don't know if they are national or what) and for $399 , short queen, we got a great old fashioned interspring mattress that's heavy as heck, 10 yr warranty. We added an one inch topper from Amazon that we already had on our old p.o.s. mattress. All we could say afterwards was what took us so long to get a new mattress.
