This mattress arrived packaged very well.  I never thought I would purchase a mattress in a box and especially not one that I didnt try out first.  Im so glad I got this mattress! The box was only about 18 square and 4 tall.  I never expected that it would fill out to a full queen size mattress.  The mattress was into shape within hours.  It is super comfortable, firm and supportive.  I even tried it without a box spring to see how it was.    It was comfortable but more so with one.  This is s good mattress for the price.  Definitely would recommend.
