We have had many different kinds of mattresses throughout or marriage but it wasn't untill we bought our sleep number mattress, that we slept great! Some friends of ours have on and kept telling us about it. We were very skeptical at first. It seemed like every mattress we purchased was a let down. We had a pillow top, a memory foam, every kind you can think of. We just felt tired and achey when we woke up. My husband kept going into the stores and trying out the sleep number beds. I refused to go in. The price seemed so high and what if it didn't work. We had been promised all the other mattresses were top of the line and they turned out to be terrible. We traveled full time in an RV for my husbands ministry. RV mattresses are the worst! So finally I was convinced to lay on a sleep number mattress. They did a test to show the pressure points in my back. They helped me in the store to figure out my "number". I was excited so we purchased one. It came in the mail a few weeks later. We put it together and slept on it that night. Now, we want to take it every where we go! We are rested and comfortable and even our boys want to sleep with us instead of their own beds.This mattress is defintly worth the money we paid for it! We love our Sleep Number mattress!!
