So I'm looking up my Overstock order history to find the sheets I'm currently sleeping on again so I can order a 2nd set and was pleasantly surprised to still see them available. It's not that they need replacing...the sheets are incredibly soft and durable, and still in excellent condition after 2+ years of daily (or nightly) use! I'm coming back for a second set so I have more matching pillow cases, and 2 sheet sets I can rotate instead of only having the one set. I remember when I first got them that they were "thick" and "stiff", but not to worry... they will lose that extra mass in the dryer and create possibly the softest lint you've ever felt. Even brand new they are comfortable, but they just keep getting softer as time passes. Highly recommended!
