We put a 4" memory foam topper on our mattress after the first night of sleeping on it. I like it a little brisk at night, so the air is usually running if it's over 65 outside. It rivals our home mattress for comfort and isn't hot at all. Not sure on the name brand, WalMart was our only choice, so we just bought the thickest one they had.

So went out and got new mattress. Fits perfectly. Was on sale for 70% off. It is innerspring which will be fine for us. Took trailer there and they took out the old saggy one put in the new one. Since it is standard queen it fits perfect. It is a little bet heavier but should not cause any tongue weight problems.
