My husband put this together while I organized the screws, washers, and boards. Each of the pieces are numbered on the back and the glass doors wer well protected during shipping. The last couple of steps (the doors) required some toggling and adjusting, but it was worth the patience on my husbands part. We were happy it fits the largr tv.for our guest suite and adds a bit of coziness for warmth for our COLD winters. 
Our ONLY negative, is the non realistic flames. We do have another electric fireplace and it has a MUCH nicerrealistic flame. But, this one does put out nice heat and is fine for guests.
