Extra Deep Queen 400 Thread Count Cotton Fitted Sheet - Fits 18

In this review of the Extra Deep Queen 400 Thread Count Cotton Fitted Sheet, the bottom line is simple: this single fitted sheet is designed for sleepers who need genuine extra deep pockets and natural cotton comfort. The reviewer found it particularly useful for mattresses with toppers, memory foam layers, or thick mattress pads because it reliably fits depths from 18 to 24in without slipping. Constructed from a 400 thread count sateen weave and made from 100% long-staple cotton, the sheet balances softness and breathability for warm or hot sleepers.

Key Features

• Extra deep pocket fit: The sheet accommodates mattresses and toppers that are 18, 20, 21, 22 or 24in deep, so it stays secure on very thick beds.
• 400 thread count cotton: The sateen weave provides a silky smooth surface and a durable cotton feel that softens with each wash.
• 100% natural cotton: Made from long-staple cotton yarns, the sheet offers breathability and moisture wicking for a cooler night.
• Elastic all around: Stretchable elastic sewn around the perimeter keeps the fitted sheet snug and prevents the corners from popping off.
• Hotel-inspired finish: The sateen sheen and smooth hand give a slightly crisp yet comfortable sleep surface similar to higher-end bedding.
• Made in India: The manufacturing origin reflects traditional cotton weaving and finish techniques used for long-staple cotton sheets.

Who It's For

This fitted sheet is ideal for anyone sleeping on an extra deep mattress or using a thick memory foam topper, mattress pad, or pillow top who wants a natural cotton option that breathes and gets softer over time. It works especially well for hot sleepers who prefer moisture-wicking, breathable fabric with a slightly silky, sateen finish.

Shoppers who need fitted sheets for standard or shallow mattresses will find this overbuilt and may prefer a lower-profile fitted sheet to reduce fabric bulk. Also, if someone requires a specific blended fabric or an ultra-lightweight percale, this 400 thread count sateen cotton may not match that exact feel.

Pros & Cons

Pros

• Fits very deep mattresses (18 to 24in) and stays in place thanks to elastic all the way around.
• Soft, silky sateen hand from 400 thread count long-staple cotton that improves with washing.
• Breathable, natural cotton helps regulate temperature for warm sleepers.
• Hotel-like finish and durable construction for regular use.

Cons

• Its extra depth can feel bulky on low-profile beds, so it is not ideal for shallow mattresses.
• Only available as a single fitted sheet in this listing, so coordinating flat sheets or sets must be purchased separately.
