Why You'll Love a Juno California King Mattress

Incredibly Spacious

A California King bed gives you plenty of room to stretch out and relax. It's longer than a king-size mattress so if you're tall, or share a bed with a partner or pets, this mattress is for you.

California King mattresses are also slimmer than a king-size, so if you're limited on bedroom space but still need a bigger bed, you're in luck. Plus, Juno is conveniently delivered right to your door in a box, so setup is a breeze!

"We love our Juno California King bed. We co-sleep with our little girls and I’m glad we’re not waking them when we’re in and out of bed. The softness and stability is just right, I never experienced any back pain since we had it."

Fantastic Motion Isolation

Is your sleep interrupted by movements from your partner or pets? Juno mattresses specialize in eliminating sleep disturbances caused by movement.

Juno's expertly crafted foam layers absorb movements fast, limiting motion transfer from one side of the mattress to the other. It's the perfect solution for couples who want to enjoy a restful night's sleep together but also need their own undisturbed space.

"Wonderful quality, so comfortable, incredibly easy to set up, almost no motion transfer, and excellent value. I cannot recommend Juno enough."

Sleeps Comfortably Cool

The Juno California King mattress is a game-changer for hot sleepers. Its increased surface area and cooling gel memory foam keeps you at a comfortable temperature all night long.

You can also upgrade your Juno mattress to include the Cool+ Cover for only $79. It's infused with an innovative cooling yarn designed to wick away moisture and dissipate body heat fast even faster.

"My wife and I are in love with our Juno mattress! As a hot sleeper, the Cool+ cover is amazing. Nice and cold to the touch, but in the best way. I wish I had heard of this company a long time ago and hadn’t wasted my money on multiple lower quality mattresses in the same price range. You really can’t go wrong!"
