Enhance your RV sleeping comfort with this custom-fit Corner Cut RV Mattress Topper. Designed specifically for 73" x 50" RV beds with a 21-inch right-angle corner cut, it eliminates excess overhang while maximizing your sleeping space. The 3.2-inch dual-layer memory foam delivers superior pressure relief with a soft 30D comfort layer and a supportive 30D base layer to prevent sagging.
Stay cool all night thanks to the breathable knitted fabric cover, which promotes airflow and temperature regulation. The removable, machine-washable cover makes cleanup effortless after every trip. Perfect for travel trailers and motorhomes, this topper is a great upgrade from thin factory mattresses, compatible with most major RV brands.
