My 2010 Comfortaire bed is awesome and the top foam comfort layer started to compress. I stayed with the Comfortaire recommended standard convoluted foam rather than the memory type foam. This bed doesn't get hot and I wanted to keep it that way. The price was right and the fit was perfect, so I didn't have to cut up a new one. I will say the the Comfortaire telephone rep. gave me a much, much higher price than the manager who I emailed did. Luckily, I mentioned the sales persons name and the price and didn't overpay, so, watch out.
