There are so many duos that are not able to sleep comfortably as their partner is so restless and uncomfortable with their bed. It is not very easy to get a mattress which both the husband and wife are comfortable in. This is where sleep number beds come in to play their role. You can adjust each side of this mattress to as firm or as soft as you want it to be. And you can also make it warm or cool according to your requirement. The slopes of the mattress are also prone to adjustability.
