It would be a fistfight between a Tempur-Pedic mattress and adjustable base and a MacZcliner, so we have to figure out who's going to win. The fabulous MacZcliner or the Tempur-Pedic.
I generally sleep in the MacZcliner half the night, then I climb into a Tempur-Pedic, so it would be a dead heat, as they would say in the horse racing business.
