You'll have sweet dreams when you're sleeping on MyBob's Premium Modal Sheet Set! That's because each piece of this set enables you to sleep soundly. For instance, the fitted sheet has an elastic cuff and perfectly fitting corners to prevent it from slipping off of your mattress. Then, the flat sheet contains an additional four inches of material for complete coverage of your bed! Last but not least, each pillowcase is enveloping so it will securely cover your pillow throughout the night. Let's talk about the smooth feel of these sheets, too. Premium long-staple cotton is combined with Lenzing Modal fibers to get this super-soft sateen woven blend. The full-length elastic and deep pocket design fit mattresses up to 18 inches thick, making this sheet set versatile across a wide variety of mattresses. You just can't go wrong!
