Needed a queen mattress quickly for guests.  Wayfair delivered the mattress in a box. It was easy to open and set on the bed frame. The instructions were excellent and even included a special tool to cut open the plastic wrap. Like magic, the mattress unrolled and puffed up to a nice plush and very comfortable bed. Instructions recommended letting the mattress air and fully  inflate for 72 hours. Very pleased with the purchase.
