These sheets are High quality & soft out of the box, but they will take at least 1-2 washing to start feeling silky soft. As with all Egyptian cotton products, the more times you launder them, the softer the material feels. High thread count Egyptian cotton fabric is incredibly strong and will last for many, many years. If cared for properly, Egyptian produced cotton fabric used for bedding products can last for decades. This is why high end Hotels use quality Egyptian cotton products like these sheets. Sheets that sell for half the price and have 1/3 of the thread count, are not of this quality, nor will they last as long as these will. The weight of the fabric is heavy and the construction is fine. You cannot see through the fabric, unlike most other low count fabrics, this is tightly woven and the threads are thick. The cotton has a sheen and feels satin like. The pillow cases are over sized and have a heavy scroll embroidery on them. The fitted sheet fits an 18" Deep mattress, I own a Select comfort I10 with an 18" pillow top, these fit perfectly. These sheets are worth every penny! Please do not hesitate to purchase them. These are made in the USA.
