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."

Some mattresses don’t contour to your shape, which can leave pressure points in your shoulders, back, or hips.
Memory foam gently molds to your body, relieving pressure and helping your muscles relax so you can fall asleep faster and stay asleep longer.
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.
Poly foam gives the mattress a plush, gentle layer that helps your body settle in and get comfy right away.
Without the right balance, soft foams can feel too sinky and unstable.
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.
Old-school spring mattresses can creak, bounce, or transfer motion too easily when someone moves.
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.
Have you ever laid on a mattress and just sunk straight to the ground?
Base foam makes sure you don’t sink straight to the ground when lying on your mattress, keeping proper support all the way through.

How Your Sleep Gets Better Each Week
A new mattress takes a few weeks to break in and settle to your body. Here’s what most people notice along the way.
Weeks 1–3Weeks 4–7Week 8+
Your body is getting used to the new feel, and you’re already waking up less hot.
The first few nights can feel a little firm while the foam breaks in. It softens a bit more each night, and the cooling gel is at work from night one.
- Let it fully expand before the first night
- Use breathable sheets so the gel can do its job
The foam has settled to your shape, and you’re falling asleep faster with fewer wake-ups.
By now the comfort layer has fully broken in. Pressure on your hips and shoulders eases, and most people stop noticing the mattress at all.
- Rotate it head to foot once this month
- Still deciding? You have 100 days from the order date
This is your new normal: cool, comfortable sleep you don’t have to think about.
The gel keeps drawing heat away all night, every night, and the foam keeps you comfortably supported.
- Rotate it every 3–6 months to keep the feel even
- Spot-clean the cover as needed
Wake Up with Less Pain, Guaranteed
If you are not feeling better and sleeping with less pain, return your mattress within 100 days of the order date and we will give you your money back.
