This is the second hybrid mattress I've received from Wayfair and I am extremely happy with both.  The mattress came air vacuumed, folded and rolled into a very manageable sized box (see second pic). I used the tool they included to cut the plastic wrapping and like magic, the mattress started to take shape.  After about an hour, it was almost the size it is supposed to be, but needs a full 12 hours to fully reshape.  The mattress is extremely comfortable and well made.  I now favor hybrid mattresses over the typical mattress, great product!!
