My husband and I have had the Sleep Number 3000 California King bed for over three years now and we absolutely love it! Before this bed, we used to sleep on the traditional spring mattress beds. Now that we have slept on the sleep number mattress we will never have any other bed but this kind!
Not to sound too much like the commercial, but everything they say is completely true. I like my bed softer than my husband. With this bed we can each be comfortable and get a great night's sleep. I occasionally have a back ache and can adjust my side as needed to get more support.
Our bed is a California king size which give us ample room to move around. Our dog can even sleep in his own space! We chose the standard legs for the box frame. They are strong enough to support the bed and small enough to blend into the look for the bed.
I would (and have) suggest to everyone that they try this bed for the free trial period. You have nothing to lose and you may never want to sleep on anything else once you sleep on it once.
