Extra Deep Split King Sheet Set Black - 7 Piece Cooling Fit

In this review of the Extra Deep Split King Sheet Set Black the bottom line is simple: these sheets are for sleepers with very tall mattresses or thick toppers who want a soft, breathable microfiber set that stays put. The reviewer found the single biggest reason to buy is the extra deep fitted sheets with stretchable elastic that reliably hug mattresses with pockets up to 24 in deep, making them a practical choice for pillow-top or memory foam setups. The set feels notably soft compared with standard cotton and includes four oversized pillowcases for a tidy, secure sleep surface.

Key Features

• Extra deep fitted sheet: Fits mattresses with 18, 20, 21, 22 and 24 in pockets so tall beds and toppers stay covered without popping off.
• Stretchable elastic: Elastic around the fitted sheet provides a snug tug around the mattress so the corners remain secure through the night.
• 7 piece set: Includes a flat sheet, an extra deep fitted split king and four oversized 20 x 40 in pillowcases for full coverage and matching accessories.
• Microfiber softness: The soft microfiber weave has a light, cozy feel that reviewers note is even softer than many cotton sheets.
• Great for pillow tops: Designed to accommodate 3 in and 4 in toppers, memory foam and thick mattress pads without slipping.

Who It's For

This set is aimed at owners of split king beds with extra thick mattresses or added toppers who need deep pockets that actually fit. It is ideal for people who prefer a very soft, lightweight sheet feel rather than the crisper hand of cotton.

Those who prefer a crisp cotton texture, natural fibers, or require temperature-regulating performance tied to materials like linen or bamboo may want to look elsewhere. Also, if you need fitted sheets for a single non-split king mattress, confirm the split king dimensions before buying.
