Love the mattress in a box, but this one didn't come with unpackaging instructions like the others we purchased from Wayfair in the past.  It took about 5 days to relax and firm up.  Its a decent mattress for our needs, but not as good quality as other mattresses of this type we purchased before.  It makes some noise when you move around on it but not so much as to be disturbing.  I would probably purchase a different brand next time.  Ok mattress for the price.
