You’d think we’d be better at sleeping, since we’ve been doing it since before we were biologically human. But we’re not. Luckily, Leesa is looking to improve our sleep where nature couldn’t. Their 100% American made, premium foam mattresses start at $525, come with a 100-night risk free trial, and ship, for free, directly to your door. They even donate 1 mattress for every 10 sold to a shelter. As a bonus, the mattress is compressed before it’s shipped and watching a mattress inflate is a lot more fun than you’d think. Best of all, Cool Material readers will get $75 off a Leesa mattress with code cool75.
