This quilted knit cover is made from durable, spun yarns to provide extra comfort, super-soft stretch, and easy care. Thoughtfully designed for hot sleepers, it’s also woven with Chill™ cooling fibers for cool-to-the-touch comfort the moment you lie down.

Found in the quilt layer of the mattress across models, SealyCool™ Air is a super-soft version of our high-quality traditional foam formed with peaks and valleys for added airflow and ultra-cushioning comfort the moment you lie down.

Durable coils designed for quality comfort and a firmer level of support. They’re also individually wrapped which allows them to move independently–reducing motion transfer so you’ll feel less movement from your partner throughout the night.

You don’t have to take our word for it. Our foams undergo thorough third-party testing to ensure they meet CertiPUR-US® safety standards for emissions, content, performance, and durability so you can rest easy.
