RV size foam mattress plus topper (ITP, NE Atlanta near Northlake)

The foam mattress measures 72” x 4” x 30”: 3” of white foam with a denser 1” layer of green foam. The purple topper measures 72” x 2” x 30”. There is a gripper piece to put between the two to keep them from sliding. My 4 yr old grandson used them for two weeks and slept well. There are yellow stains around the edges of the white foam from the wood stain that was used on the daybed.
