Amazon Basics Cooling Bed Sheets King — 4-Piece Blue Set, Lightweight Breathable Fabric & 15" Deep Pocket

These Amazon Basics Cooling Sheets are a four-piece king set made from a lightweight 90% nylon / 10% spandex fabric designed to feel cool and breathable for warmer nights.

Made to help hot sleepers find a more comfortable night's rest, this set includes a deep-pocket fitted sheet, a flat sheet, and two envelope-closure pillowcases in a calming blue. The engineered fabric combines stretch with a smooth hand-feel so the sheets drape neatly over mattresses up to 15 inches deep. Certified Made in Green by OEKO-TEX, the set also meets independent standards for lower environmental impact and the absence of harmful substances.

How do these sheets keep you cooler at night?

The fabric blend feels lightweight and encourages airflow across the skin, which helps with perceived coolness during warm nights. Nylon provides a smooth, slick surface while spandex adds a slight stretch for better fit and movement.

• Engineered lightweight 90% nylon / 10% spandex fabric for an airy hand-feel
• Smooth surface reduces friction and helps moisture move along the fabric
• Breathable construction promotes airflow across the sleep surface

Will the fitted sheet fit my thick mattress?

The fitted sheet is made with 15-inch deep pockets so it can accommodate most extra-thick mattresses and mattress toppers. Elasticized edges hold the cover in place for a neat, tucked look that resists shifting during the night.

• 15-inch deep pocket fitted sheet fits many pillow-top and mattress-topped beds
• Elastic all around secures the sheet to the mattress corners
• Stretch in the fabric helps ease installation and reduces bunching

How do I care for these sheets to preserve their feel?

These sheets are machine washable for everyday convenience; tumble dry low or hang to dry to maintain softness and reduce wear. Washing in a large-capacity machine helps prevent excess wrinkling and allows the fabric to move freely during the cycle.

• Machine washable; use large-capacity washer for best results
• Tumble dry low or hang dry to preserve texture and fit
• Avoid high heat to maintain elasticity from the spandex content

What does the OEKO-TEX Made in Green certification mean?

Made in Green by OEKO-TEX indicates the product was tested for harmful substances and produced in facilities that follow environmental and social standards. The certification signals independent verification of safer production practices rather than performance guarantees.

• Tested for restricted substances to limit chemical exposure
• Produced in facilities meeting environmental and social criteria
• Traceable production chain offers added transparency

Who is this for: These Amazon Basics Cooling Sheets are a practical option for people who sleep warm, owners of thicker mattresses that need deep pockets, and shoppers looking for an affordable, easy-care bedding set with independent safety verification. The smooth, lightly stretchy fabric suits those who prefer sheets that tuck neatly and move with you, while the OEKO-TEX Made in Green mark appeals to buyers seeking lower-impact manufacturing practices.
