The box spring arrived in a 2x8 ft box, which made it very easy to carry upstairs.  Assembly was required but it was very simple. Took me less than a half hour to put in 12 screws for the frame and then the support boards just lay across the frame. This doesnt seem to be the strongest box spring (questionable for two regularly fornicating adults), however I bought it for a 5 year olds bed and it will be perfect for that.
