The box was dumped in front of my garage and was destroyed I figured well this mattress is going back. But miraculously the mattress survived the trip as it was so well wrapped inside the box.  When we opened the outer plastic it “exploded” into a king mattress. My husband who was skeptical was very impressed.  It’s a very nice mattress and seems to be  comfortable but I will reserve my final opinion until we have slept on it a number of nights.
