My trailer came with a futon mattress and even a 4" memory form topper wasn't enough. Gave the futon mattress to my sister to use for a puppy pad.
The topper made the WM mattress even better but I couldn't reach to climb into bed and it covered up the window lever.
Mattress toppers are a good way to improve the comfort of a mattress but I'm still very pleased with my WM mattress...but then I can climb into bed.
Great choice for "Living within my means" and camping for one...
