The unit construction is very sturdy with heavy duty material, easy to assemble but must be carried out with two persons to avoid injury or accidental damage. 
It looks beautiful when fully assembled and has fitted well in my 2nd bedroom alcove. 
The unit arrived promptly as stated, and Wayfair after care customer services have been excellent with very quick response and easy resolution should any problems arise.
I have bought 5 large items from Wayfair and fully recommend them.
