This was our first time ordering a mattress online and having it delivered.  I couldn't believe that a mattress could be rolled up so tight in a box.  This is our first Memory Foam mattress.  We were very skeptical that it was going to actually pop up and form to the right size and shape but it did.  Love the mattress!  We bought it for our seven year old son and he sleeps so much better now.  I would definitely buy a Memory Foam mattress again!  Thank you, Wayfair!
