The K2 by Kingsdown

Why the “K2”?

K2 is named after the famous mountain peak, and the theme fits perfectly. Just like the frosty summit, the K2 mattress is designed to stay remarkably cool, even when the temperatures outside are hitting the upper 90s. (For context, it was already 70° when I drove into work at 7 a.m. this morning!)

Who Benefits from a Cooling Mattress?

A lot of people sleep hot—sometimes due to body temperature, health factors, or simply the heat of summer. If you’re someone who constantly flips to the “cool side” of the pillow or wakes up feeling overheated, a cooling mattress can make a world of difference.

What Makes the K2 So Cool?

The K2 is packed with cooling features from top to bottom:

1. A Cooling, Washable Cover

The first thing you notice is the cool-to-the-touch cover. It’s genuinely refreshing the moment your hand makes contact. Better yet, the entire top panel zips off for easy washing, making it both functional and convenient.

2. Cooling Memory Foam

Just beneath the cover is a comfort layer made of cooling memory foam. Even through light pressure, you can feel the temperature difference. This foam is engineered to pull heat away from the body and create a consistently comfortable sleep surface.

3. Heat-Dissipating Channels

Inside the mattress are built-in channels that help absorb and release heat. Instead of trapping warmth—like many traditional foams do—the K2 actively disperses it to keep the surface cool throughout the night.

Don’t Forget the Cooling Accessories

A cool mattress is great—but pairing it with cooling accessories makes it even better.

Cooling Pillows

We carry pillows like the Blu-Tek Ice, which uses a similar cool-touch cover. If you often wake up with a warm head or neck, this can be a game changer.

Cooling Mattress Protectors

Adding a Blu-Tek Ice cooling mattress protector not only keeps your mattress clean—it actually enhances the cooling experience. Even if you’re not ready for a whole new mattress, this protector can make an existing bed feel cooler during the hot summer months.
