Before this, I was sleeping with a satin-polyester comforter. It was very expensive and very uncomfortable so I brought my duvet out from storage to give this a try. From the description I could not figure out the GSM of the microfiber; the higher the GSM the thicker the sheet is. However I compared it to my cheap 90 GSM sheets and quickly noticed this was much thicker. I washed and dried it cold on delicate and luckily it stayed intact. Now that I've slept with it I could not be happier to throw my old comforter away. It's very soft and the pin tucks seem well sewn. The matching pillowcases are the perfect touch. Very happy!
