Mellanni Extra Deep Pocket Cal King Fitted Sheet - Fits Up to 21in

In this review the Mellanni Extra Deep Pocket California King fitted sheet stands out for anyone with a tall mattress or thick topper who needs a dependable fitted sheet that simply stays on. The single biggest reason to buy is its true extra deep pocket design and all-around elastic that secures the sheet on mattresses up to 21in deep, so sleepers with pillow top mattresses, memory foam toppers, or adjustable beds can stop wrestling their bedding each morning. The fabric feels silky soft and the construction promises low-maintenance care.

Key Features

• Extra deep pocket fit: Designed to fit 17in to 21in mattresses so it accommodates tall mattresses, toppers, and pillow top beds with room to spare.
• All-around elastic: Mellanni Signature Z-fold elastic edging runs around the entire sheet to keep it in place and reduce shifting during the night.
• Brushed microfiber: Double brushed microfiber offers a silky soft hand that is comfortable and more durable than basic cotton in everyday use.
• Easy care: Machine wash cold and tumble dry low for quick drying; sheets resist fading, staining, shrinking, pilling and heavy wrinkling.
• Versatile use: Sized for California King beds at 84in x 72in x 21in and suitable for bedrooms, guest rooms, RVs, and vacation homes.
• Lifetime customer promise: Backed by Mellanni Lifetime Promise for returns with no questions asked if the buyer is not satisfied.

Who It's For

The fitted sheet is ideal for owners of extra tall mattresses, memory foam and pillow top beds, mattress toppers, or anyone using an adjustable bed who needs a deep pocket that will not slip off. It also works well for renters and vacation properties where durable, low-maintenance bedding is preferred.

Shoppers who prefer natural fiber sheets or who need a fitted sheet for a mattress under 16in should consider a different collection; Mellanni suggests their Classic collection for shallower mattresses. Those seeking a fitted sheet with a very heavy, breathable fabric for hot sleepers may also want to compare materials before buying.

Pros & Cons

Pros

• Deep pockets and strong all-around elastic keep the sheet secure on mattresses up to 21in.
• Fabric is ultra-soft and smooth thanks to double brushed microfiber, which many customers liken to silk.
• Low-maintenance care: resists fade, stain, shrink, pill and wrinkles and dries quickly.
• Good value and color accuracy make it a practical choice for multiple rooms and gift giving.

Cons

• Microfiber is synthetic, so shoppers wanting natural fibers like cotton or linen should look elsewhere.
• Some may find the silky finish warmer than crisp percale if they sleep very hot.
