  • When it comes to mattresses, one size definitely doesn’t fit all. The mattress should be longer than the tallest person sleeping on it. The bed width should allow enough space to fold your arms behind your head without going beyond the mattress edge or touching your partner’s elbows (for two adults, we recommend either a queen or a king).

Overview & Specs

Outlast Bedding Temperature Regulating Sheet Set in Linen
Not Available in Stores

Stay cool and comfortable every night of every season tucked into this Outlast Temperature Regulating Sheet Set in Linen. Originally developed for NASA, these innovative sheets feature Outlast® technology that utilizes phase change materials (PCM) to proactively manage heat and moisture and give a better, more comfortable night's sleep. The Outlast® technology is comparable to ice in a drink; as it changes from solid to liquid, it absorbs heat and cools the drink, keeping that drink at the desired temperature for longer. Outlast® phase change materials will also release heat throughout the night as needed to keep you at a balanced temperature. Crafted with a sumptuous 40 percent Outlast fiber and 60 percent cotton fabrication that absorbs, stores, and releases heat to balance the temperature around your head and neck for optimal sleep comfort. The Outlast® technology is tested and proven to alleviate spikes in skin temperature that cause sleep disturbances.

Sometimes, even the highest quality products may show early signs of wear and tear, or have a manufacturing defect. Most products available at Mattress Firm are covered by a manufacturer’s warranty.
