Clara Clark's Premier 1800 Collection deluxe microfiber sheets are made of luxuriously silky brushed microfiber fabric. Soft and breathable, they wick perspiration away to let you sleep in comfort. And for a touch of elegance, the pillowcases are detailed with classic three-line embroidery. Available in a wide range of tasteful, fade-resistant colors, the sheet sets include a fully elasticized fitted sheet that accommodates extra-thick mattresses.
