Hearth & Harbor Extra Deep Pocket King Sheet Set - Fits 18-24in, 6 Piece, Grey
Hearth & Harbor's extra deep pocket King sheet set that fits 18-24in mattresses, 6 Piece in grey for full bedding coverage.
Tall sleepers often stack a topper on an already thick mattress for the extra length and cushion, and a normal fitted sheet simply cannot wrap that depth. The corners strain, ping loose in the night, and you wake up on bare mattress with the sheet balled at your feet. These king fitted sheets use extra deep pockets and strong elastic built to hug taller mattress-and-topper stacks. Measure your mattress depth with the topper on before choosing, and give yourself a little margin so the corners hold.
