Replacement mattresses?

I am looking to replace the queen mattress we have in our trailer, what suggestions does everyone have?

I went with the Amazon Basics brand one but it is a bit longer then normal RV queen, anything is better then the one it comes with…

Denver Mattress of Furniture Row fame makes a RV Queen

My wife and I purchased a queen Sleep Number aka Select Comfort mattress years ago. When we got our new TT we swapped the mattresses. Love it

We added 3" memory foam mattress topper to our bed and also to the bunk beds. Love it!
