King Size Fitted Sheet 100% Egyptian Cotton 600 TC - Deep Pocket Fit

In this review the Mayfair Linen king size fitted sheet is recommended for sleepers who want a durable, soft fitted sheet that stays put on thick mattresses. The single biggest reason to buy is its deep pocket design combined with a 600 thread count sateen weave made from long staple Egyptian cotton, which delivers lasting softness and a secure fit; this review focuses on real use, wash performance, and fit over mattresses up to 16-18 in. The sheet reviewed is the fitted sheet only, sized 78in x 80in, and it aims to replace frequent re-tucking with a one-and-done bed make.

Key Features

• Deep pocket design: 16in pockets and elastic on all sides keep the sheet tucked under mattresses so it rarely pops off during the night.
• 600 thread count sateen: A sateen weave from extra long staple cotton gives a smooth, slightly lustrous surface that becomes softer after a few washes.
• 100% Egyptian cotton: Long fibers increase softness and durability compared with shorter staple cottons, making the sheet feel substantial without being stiff.
• Mercerized finish: An extra mercerization step improves dye depth and resistance to fading and pilling through repeated machine washing.
• OEKO-TEX STANDARD 100 certified: Certified free from harmful substances, making it suitable for sensitive skin and for children.
• Easy care: Machine wash gentle and tumble dry low maintains color and softness with routine weekly washing.

Who It's For

This fitted sheet is best for people with thick mattresses who need a reliable deep pocket fitted sheet that holds its place overnight and through active sleep. Couples, hot sleepers who prefer breathable natural cotton, and buyers who want sheets that soften after a few washes will appreciate the sateen finish and long-staple cotton construction.

Shoppers who prefer a full bedding set rather than a single fitted sheet should look elsewhere, since this listing is for the king fitted sheet only. If a very crisp percale feel is required, a sateen weave will feel silkier and less crisp than percale.

Pros & Cons

Pros

• Secure fit from 16in deep pockets and elastic on all sides keeps the sheet in place.
• Soft sateen hand that improves after several washes thanks to long staple Egyptian cotton.
• OEKO-TEX certification and mercerization reduce pilling and color fading over time.

Cons

• Slightly heavier, satin-like sateen may not suit shoppers who want a crisp percale feel.
• Body fabric thickness receives mixed feedback from some customers who expected a different hand feel.
