It was very well packaged, the matress was well wrapped and compressed into a small roll, after unpacking, just allow a few minutes for it to expand. I would recommend carry it to the room before unpacking because once it is fully expanded, it becomes much bigger and hard to carry. It is a great mattress, the firmness level is just right - firm but not too firm. Seems well made and no off-gassing. Overall I'm very pleased.
Output:
positive
