King Size Fitted Sheets

King Size Fitted Bed Sheets — Built for the Widest Bed in the House

A king bed is usually a shared bed, and width is the reason people buy it. A king size fitted bed sheet covers more edge and wider corners than any smaller size, and often sits on a thicker mattress, so pocket depth and elastic matter. Our king fitted sheets have elastic that wraps the entire edge, not just the corners. Pocket depths vary by program: 16" on cotton sateen king; 15" on organic cotton king. The fabric is 100% natural cotton, tested for pilling and shrinkage. For our complete range of 100 cotton fitted sheets king size across every weave, explore the full collection.
