My husband has suffered from back pain as well as a broken hip&surgery and a number of vascular surgeries, so this bed was a "gift from heaven" once we got it inflated, which only took 2 days (flipping the mattress over 2X for each side) he slept like a "baby" and woke up with out pain! So thank you for all of the ease of this purchase, but also for the wonderful product this mattress is.
