This mattress arrived SO quickly…I had it within a few days of ordering! I got the twin mattress, which arrived vacuum sealed in a box. It was pretty heavy and cumbersome. It  came with a handy razor blade, letter opener thing to tear the plastic. As soon as the plastic was torn, the mattress started to inflate. This thing was flat and ready to use in seconds. So soft and plush. It’s also deeper than an average mattress. Very happy with this mattress for my guests.
