It is always good to have a princess along when you shop for a mattress. She is very impressed that I got a "Queen". She tried every mattress at the store, and, even more impressive, the baby was sleeping on a bed through the entire process.
Our mattress was from the seventies. It belonged to an ex roommate's parents before they got divorced. Our new mattress is nothing short of a miracle. So clean, so puffy. You know where I'll be.
