I had not purchased a new bed in more than 12 years. I decided to purchase a new bed because I had full hip replacement surgery scheduled. Thinking I might need to adjust to a new bed I purchase my bed 30 days before surgery was scheduled. Since the very first night on my Hybrid Premium Firm Tight Top Sealy bed I've slept comfortably and gotten up with less lower back and shoulder discomfort. The adjustable function of my new bed was a tremendous help during my recovery, allowing me to adjust my body position before trying to get out of bed. I would recommend your bed with adjustable base to anyone facing hip replacement surgery. Thank you!
