400TC or more. I love sleeping in super soft sheets. We spend so much of our life sleeping that I say buy quality bedding. Invest in your life. Feel the difference. Avoid bed in a bag sales. Crap in a bag I call it. Look for a good sale and buy a good pair of sheets a year. Invest in at least 3 sets and 2 duvets and you'll be so happy you did. Happy Sleeping!!
