Not sure why they brag about this one
we didn't even try to use it without adding a topper and mattress pad:
Beautyrest 3-inch Sculpted Gel Memory Foam Mattress Topper - Overstock Shopping - The Best Prices on Simmons Beautyrest Memory Foam Mattress Toppers
Amazon.com: Short Queen Mattress Pad Mattress Cover for Camper, RV, Travel Trailer Mattresses Size:60x75: Home & Kitchen
The topper is full queen length but it's easy to trim a few inches off the bottom. Now that we've used this setup a few times I can honestly say it's really comfortable and we sleep real well on it.
