I am completely in love with my new 4 layer latex (Dunlop xfirm, Dunlop firm, Dunlop firm, Talalay med) mattress from Foam Sweet Foam. For some reason, the 4 layers is so more comfortable than the 3 layer version I have now in the guest room (which was great to begin with). Both beds are much more comfortable than the Casper guest bed I have in my opinion.
