walmart spa sensations 6" memory foam mattress

We have the 8 inch SS in our Class C for about 2 months now and it is very comfortable. I don't know about durability yet as we haven't had it long. I think we paid about $199 so it was very inexpensive so you can afford to replace it more often if the durability isn't that great.

We also kept the memory foam topper that we had on our previous matress (we probably don't need it).
