Upon unpacking my Madison Park 1500 Thread Count Cotton Rich Sheet Set, I noticed a chemical like smell. Immediately they were washed and then dried in my washer and dryer. I am happy to report that the smell was gone, and the sheet set was wrinkle free, after removing them promptly from the dryer. These was no need for touch up ironing. I am really a stickler for a beautiful looking and neat bed. These were showroom quality. The sheet color that I selected was a light bluish gray sheet. They fit my 12 inch mattress very generously. Actually they may even fit a thicker mattress. The finish of these 52% cotton and 48% polyester blended (Made In India) sheet set is similar to that of sateen sheets as they are very smooth, lightweight and cool to the touch, which makes for very comfortable sleeping. A good night's sleep is the ultimate reward !
