Drumroll, please... Meet my top-of-the-line Bob's Twilight™ Mattress, available in plush, firm, or dual. I went heavy on the premium foam (6 layers, to be exact), including a top layer of my ventilated Bob-O-Pedic Gel Memory Foam with Charcoal that's zoned to provide you with support where you need it most! And just to make sure you stay extra cool and comfortable, my special foam for airflow and cooling cover should do the trick!
