Hearth & Harbor Extra Deep Pocket King Sheet Set - Fits 18-24in, 6 Piece, Grey Review (2026)

Who this sheet set suits

Tall sleepers and anyone using a thick mattress, memory foam topper or pillow top know the frustration of a fitted sheet that pops off the corners overnight, and that is the exact problem Hearth & Harbor's extra deep pocket design is built to solve. The fitted sheet stretches to fit mattresses between 18 and 24 inches deep, well beyond the 14 to 16 inch pocket depth standard sheets typically offer, which matters more for taller sleepers since they are statistically more likely to sleep on thicker mattresses built for extra support. The 6 piece set bundles a flat sheet, fitted sheet and four pillowcases, so households that go through pillowcases faster than sheets, or that simply want a spare set on hand, get more use out of one purchase than a basic 4 piece set offers. It suits deep mattress owners more than anyone with a standard depth bed, where the extra pocket depth offers no real benefit.

Material and fit explained

The sheets are made from 100 percent microfiber that is double brushed on both sides, a finishing process that raises a soft nap on the fabric surface for a smoother, less crisp hand feel than cotton percale. Deep pockets combined with elastic running all the way around the fitted sheet, rather than just at the corners, are what let it grip a thick mattress securely instead of slipping loose during the night. Hearth & Harbor markets the microfiber as resistant to pilling, staining, shrinking and wrinkling, properties that generally hold up better on microfiber blends than on natural fiber sheets, which tend to wrinkle more and require ironing to look crisp. The grey colorway is a practical choice for hiding minor wear and matching a range of bedroom palettes without needing to coordinate carefully with existing decor.

Living with it: care and daily use

Care is straightforward: the set is machine washable and can go through a tumble dry cycle, without the special handling natural fiber sheets sometimes need to avoid shrinkage or excess wrinkling. Microfiber's resistance to wrinkling means the sheets can come out of the dryer looking presentable without ironing, a real time saver for anyone who does not enjoy that chore. The elastic-all-around fitted sheet design holds its grip through a full night of movement, which matters most for anyone who tends to toss and turn, since a loose corner in the middle of the night is a common complaint with standard elastic-corner-only sheets. Extra pillowcases from the 6 piece count mean laundry day is more flexible, with a spare set ready while the others are being washed, rather than sleeping on a bare pillow in the meantime.

Trade-offs and how it compares

Against CGK Unlimited's extra deep King fitted sheet, which focuses on a single fitted sheet rather than a full set, Hearth & Harbor's 6 piece bundle offers more value for anyone who needs a flat sheet and multiple pillowcases rather than just a fitted sheet replacement. Against other extra deep pocket options in this depth range, most of which use similar double brushed microfiber construction, the differentiators come down to piece count and color choice rather than dramatic material differences. The clearest trade-off across this whole category, including this set, is fabric feel: microfiber is soft, affordable and easy to care for, but it does not replicate the crisp, breathable hand of long staple cotton percale that some sleepers specifically seek out, particularly in warmer climates.

Verdict and who should pick something else

This set is a practical, well-rounded pick for tall sleepers or anyone on a thick mattress who needs a fitted sheet that actually stays put, backed by genuinely deep 18 to 24 inch pockets and a useful 6 piece count that includes spare pillowcases. The double brushed microfiber keeps care simple and resists wrinkling, making it a low maintenance choice for busy households. Shoppers who specifically want breathable, natural cotton sheets, or who only need a single replacement fitted sheet rather than a full set, should look elsewhere, since this set's strengths are built around convenience and fit rather than a premium natural fiber feel. For a deep mattress that keeps losing its sheets overnight, this remains one of the more dependable fixes available.
