We bought the Memory Foam Topper to put on a Yawn double blow up bed to use in the Awning when we go caravaning. Although we haven't used it in the awning as yet we have found that the Memory Foam Mattress makes the Blowup Bed much warmer and much more comfortable. I will most likely purchase another one. And may I add. I did not find that there was any smell from the Mattress as other customers have stated in their reveiws.
