Our 2012 Wildcat Sterling edition came with a Trump Suites matteress. I was prepared to toss what ever came with our rig but to my suprise it was a very comfortable mattress.
Best mattress I've had in an RV.
I fully expected it to break down quickly with the plan to swap it out with an extra select comfort queen we have in our guest room at home.
It's now 3 1/2 years since we purchased our 5er new and the bed is still going strong without the need to modify with a topper.
I just wished other issues were avoided as well as the mattress was.
