My husband and I love this bed! It has the perfect thickness and firmness. We work opposite schedules 5 days out of the week, and were often woken up by other when they would get in or out of bed. Now we don't. Even past experiences with beds, just simply rolling over would wake me up ( mom ears/super light sleeper), but with the Perfect Sleeper, I truly do get the perfect sleep. We are both well rested each and every day. Thank you Serta.
