Bought this adjustable frame for my mom who has fractured verberates in her back. She loves the zero gravity & various massage settings. Lumbar support is also very comfortable for her! It's easy for her to adjust throughout the night & sleep tracker on her phone is also a major plus. Would highly recommend for those who have trouble sleeping and/or painful to lay on a flat mattress! I plan to get one for myself next time I need a new mattress & frame.
