Was having horrible hip pain on my old 7 inch foam mattress and decided to take the leap and get ghost bed flex. This bed (only 2 months in) is the TRUTH. No hip pain, great sleep. The bed doesn’t measure out to 13 inches as advertised but it’s pretty close. So far I’m happy with the purchase. If you’re looking for a good hybrid mattress at a fair price definitely look into this bed. Great for side and back sleeping.
