I have had the sleep number bed since it first came out on recommendation of my chiropracter. Best money I ever spent. There was no adjustment period, slept thru the night the very first night. And I have had less headaches since then as well. What I would really really want now is the adjustable head and feet one but just can't justify $6,000.00. Good thing about both sleep # and tempurpedic is you have either 60 or 90 day return policy if you do not like them.
