OK. solve this:
We received our comforter, and it was not the dimensions advertised. We contacted the seller(Egyptian Cotton Factory Outlet Store) and the claimed manufacturer (Warm Things). The manufacturer responded quickly to tell us that this seller does not have access to their products. The seller has copied the language from the manufacturer's website and is selling fraudulent products in their name. If you care about the quality or dimensions of the comforter you're buying, don't buy from them.
Answer:
Negative
