ELASTIC CORNERS BUILT IN - What separates our bed sheets from the rest are the special elastic sheet straps built in. These elastic corners keep your fitted sheet secure to the bed and come on all of our sheets. SLEEP IN LUXURY – No more sleepless nights on uncomfortably itchy sheets! Sleep soundly on the softest 1500 Supreme Deluxe Collection sheets. Be warned, though: You may never be an early bird again! SUPERB SHEET SET – Each luxurious set has 1 fitted, 1 flat sheet, and 4 pillowcases (NOTE: Twin & Twin XL sizes include 2 pillowcases). Deep pockets, thick elastic, and BUILT IN SHEET STRAPS make your new soft sheets stay in place! STAY CLEANER, LONGER – Who has time to wash their sheets every few nights? When it’s time for a wash, machine wash cold, and tumble dry low. PERFECT FIT FOR ANY BED – Sleep soundly for years to come! Your deep pocket sheets are fade, shrink, and wrinkle resistant. We’ve got you (and your bed) covered.
