Lucid Memory Foam in 2306 Murphy Bed
We just replaced our factory mattress with memory foam and couldn't be happier. bought a 60x80 Queen memory foam from amazon, 8" thick LUCID model for about $250. Unzipped it from the fabric, cut it to 74" length using a sharp bread knife (do it in the backyard, it's messy), and then my wife sewed it up. The 8" provides a good base. Memory foam is firm enough that if one of us rolls around the other does not feel it. 8" with sheets and 2 blankets is just right but any more blankets and you would need to drop to less than 8" to fit the bed in its latches. We lose the heated mattress but for the number of times we've used that feature it was well worth the trade.
