Sleep number bed

It's been so many nights now that I don't have a good sleep and have some back pains too.I guess it started when we replace our old mattress.The new one is so firm and not a comfortable bed to sleep on.How I wish we have a sleep number bed so that we can adjust the firmness and the comfort level that we want to.With that kind of bed,people can have a good night sleep and well rested when they wake up in the morning.
