1. Box was not too heavy and the mattress was easy to remove from vacuum packaging. 
2. There was no damage to the mattress itself
3. The mattress did not expand fully to 10" (about 9.5" after 72 hours)
4. The mattress had the most odd feeling: Sinks deeply with centralized pressure (such as stepping on or pushing hand down on it), and would indent to the bottom when sat on, feeling like quicksand. When lying flat, the mattress is so firm my limbs would lose circulation.
I am returning mattress because -It's too plush when direct pressure, yet somehow too firm when lying flat. Also, I don't think it will last very long and seems super cheap quality even though Sealy is a reputable brand.
