Watch out for Noah's... they do not honor their warrany. Noah's has refused to honor the warranty because of some sort of disagreement with the store we purchased from that has nothing to do with us. The store even moved and we looked up the Noah's warranty and it says if the store moves that Noah's will honor the warranty directly, but they are still refusing to do so. After just 2 years the mattress has a terrible dip... I mean really bad... when I showed a photo of it to a mattress store they all laughed. That is how defective the Noah's 5300 was for me.
