Grand Linen4 Pieces Double-Needle Stitch Soft Down Alternative Pinch Pleat Solid Black Comforter Set Queen Size Bedding - Plush Siliconized Fiberfill

Says "goose down alternative", but 1 reviewer called it a "quilt" & the image used is the same image for another listing described as a "comforter"???

Would this piece feel more like a heavy "blanket comforter" ? Some comforters are thick/bulky & for looks only.

What are dimensions of king vs cali king? Description is same for both.

Is the material of the comforter shiny or is it more flat?
