The boxes are much heavier than you might think, so it is definitely worth the extra money to have them deliver the boxes to the room where you will be assembling the bed.  We were quoted $450 to have someone come assemble it, but I was able to do it myself in about 10 hours.  As long as you can find studs in the wall above the frame, you can do it.  To secure it to the wall properly, you really do need to cut out two chunks of baseboard.  The boxes of parts are not labeled well, so you have to search through the boxes to find the pieces that you need.  We decided to assemble the drawer unit and put it in another part of the room.  It does not have to be attached to the cabinet frame.  Overall, we are very happy with the bed.
