Not gonna lie.... I had my doubts.  A queen bed mattress stuffed into a box?  And... I bought the Zinus bed frame to go with it.  That was my first pleasant surprise.  Unlike other furniture pieces I have built in the past, this was all quality. The way it was packaged, the "actual" tool that was included to perform the install, and... how sturdy the final product was.  Nice job!  And... I'm sleeping great!
