Real people, real answers. Our team understands what it's like to shop for a cooler, better night's sleep. Let us help you find the right mattress for you.

The CoolGel Difference

This mattress is packed with features made to help you sleep better every night. Here’s what makes it special:

icon

Premium cooling system

Stay cool from sunset to sunrise with layers that fight off heat.

icon

Multi-zone support for perfect alignment

Gives your body the right support, right where you need it.

icon

Hotel-grade luxury comfort

Super soft and cozy, like sleeping in a great hotel bed.

Cool Gel mattresses are built to help you sleep cooler and more comfortably, night after night. Each option features our gel-infused memory foam that draws away heat, combined with a supportive base that keeps your spine happy. Choose the Classic all-foam design for a soft, hug-like feel, or upgrade to Premium for a hybrid with extra support from wrapped coils.

All our mattresses contain no fiberglass and are CertiPUR-US certified for peace of mind. Whether you are a side, back, or combo sleeper, Cool Gel makes it easy to get cool, pressure-relieving rest at a price that works for real families.

We believe your mattress-buying experience should be as smooth as your first night’s sleep. Every Cool Gel™ mattress ships free to your door with no hidden fees and no surprises.

When your mattress arrives, setup is simple. Unbox it, place it on your bed frame or foundation, and allow it to naturally expand. The mattress will begin inflating right away, but we recommend giving it the full 24 hours to reach its ideal shape and comfort level. No tools or complicated assembly required. Just open, relax, and let the mattress do the rest.

We want you to fall in love with your mattress risk-free. That’s why we offer a 100-night trial on every Cool Gel™ mattress. If you’re not fully satisfied, we’ll take it back with no hassle and no restocking fees.

And because we stand behind the quality of our materials and craftsmanship, your mattress is backed by a 3-year warranty. Sleep easy knowing we’ve got your back.

Whether it’s night one or night 1,000, we’re here to help.

1 Gel Foam
When your mattress holds onto heat, you can end up tossing and turning or waking up sweaty, especially if your room gets warm
Verified Icon
Gel foam helps by drawing heat away from your body and letting cool air flow, so you wake up feeling fresh instead of hot.
2 Poly Foam
Some mattresses can feel hard or uncomfortable, making it tough to relax and fall asleep. That means you might toss and turn, trying to find a soft spot.
Verified Icon
Poly foam gives the mattress a plush, gentle layer that helps your body settle in and get comfy right away.
3 Memory Foam
Some mattresses don’t contour to your shape, which can leave pressure points in your shoulders, back, or hips.
Verified Icon
Memory foam gently molds to your body, relieving pressure and helping your muscles relax so you can fall asleep faster and stay asleep longer.
4 Supportive Poly Foam
Without the right balance, soft foams can feel too sinky and unstable.
Verified Icon
The supportive poly foam adds a firmer transition layer beneath the memory foam, giving your body the lift and alignment it needs—without sacrificing comfort.
5 Wrapped Coils
Old-school spring mattresses can creak, bounce, or transfer motion too easily when someone moves.
Verified Icon
Individually wrapped coils respond to your body’s movements while minimizing motion transfer, providing personalized support, better spine alignment, and a quieter, more stable sleep experience.
6 Base Foam
Have you ever layed on a mattress and just sunk straight to the ground?
Verified Icon
Base foam ensures that you don't sink straight to the ground when laying on your mattress, ensuring proper support all throughout.

My New Favorite Mattress

"Everyone who sleeps on it asks me where we got it and are blown away when I tell them the price. It never got a weird saggy middle and never smelled."

Unbeatable Price

"The biggest thing that I’m impressed with is I only paid $400 for the new mattress versus $4000 for a new Tempur-pedic. The cool gel mattress has yet to get warm which is another thing I needed. I like a cool mattress."

How Your Sleep Gets Better Each Week

Every new Cool Gel mattress needs a little time to break in and match your body. Here’s what most people experience as the weeks go by, so you know exactly what to expect as your sleep keeps getting cooler and more comfortable.

Week 1
  • WEEKS 1 - 3
  • WEEKS 4 - 6
  • WEEKS 8+

Your body is getting used to the new mattress and you start waking up less hot and restless.

You might notice a few nights of breaking in, but cooling comfort and support are already making sleep easier. Each night, the mattress softens a bit more and helps you relax faster.
