When you think of the different types of mattresses, what do you think of?  Many people think of mattresses that have box springs and springs inside of the mattress.  They also think of foam mattresses, like the Tempur-Pedic mattresses.  There is also another type of mattress that a lot of people forget about, and that is the type of mattress that moves and adjusts to however you want it.  These can raise the bottom of the bed to better support your legs or the top of the bed to give your back, neck, and head better support.  There are even some mattresses that allow you to change how firm or soft they are so that you can get a better quality of sleep during the night.
