It took me about 5 hours on my own (with some breaks) to fully unpack, assemble, and clean up this beautiful desk. It is VERY sturdy and it was well designed with vent or chord holes on the inside of seating area of desk instead of behind which can be unattractive unless against a wal. If you are trying to assemble this, make sure in steps 2 and 3 to put together the bottom pannel and base first before attaching it to outside pannels (parts B, C, or D, E)
