We put a topper on the queen rv mattress that came with our MH, replaced that with our residential serta and the topper, and last fall we replaced that with a 10" serta foam gel. Lighter weight than the serta from the house and no need for a topper.
The serta residential was super comfortable especially with the topper but was difficult to make up and keep it made. That's all been fixed with the serta foam gel
