Super soft, comfortable and warm.  This is my second set of flannel sheets from Wayfair but the first from this brand.  The other brand had super deep pockets with room to spare for my thick mattress and toppers (about 17  1/2 inches), but these sheets are much more comfortable.  It is advertised to fit 16 inches.  These sheets just barely can be stretched to fit the corners.  If you don’t add extra mattress toppers (I have a firm mattress with a latex and a snug fleece wool topper) these sheets will give plenty of room.  Also, I took someone’s advice and use white vinegar in place of softener for fluffy, absorbent fabrics.  Definitely would buy again,  wish they would add a couple inches to deep pockets.
