Was easy for 1 person to put together, only a phillips screwdriver is needed. It arrived in 2 boxes. One box was 76 lbs with about 36 pieces and the second box was the heater insert that only needed to be secured to the mantel. Everything was in perfect condition and looks very good and feels sturdy when assembled. The stone is the only thing that looks fake when you get close. The flame has 3 brightness levels but the light can't be turned off when the heater is running. It is a good piece, I recommend it.
