TEN-SER-45
A layer of medium-soft hybrid foam sits atop a unique slow-release foam, tying a higher support factor with incredible pressure relief. It’s finished off with a medium-firm version of one of the highest-density foam cores available on the market, making it a versatile option for any sleep position.

-
A unique foam that provides great pressure-relieving benefits without the use of memory foam, this top layer gives softness, without the feeling of sinking in. It also adds support that’s uncommon in a soft top layer.
-
A foam like no other, this layer in the middle adds superior pressure relief compared to typical transition layers, but its closed-cell air capsule structure creates far better support factor compared to memory foam.
-
An additional 2" of Ventilated Rebound Foam adds the perfect balance of pressure relief and airflow, ensuring long-lasting, cooling comfort.
-
With a foam that’s 75% more dense than a typical foam mattress core, our 2.8 density foam core is built to last. The 45 IFD (which is the measurement of firmness) provides a medium-soft feel.

Beyond Basic Warranties
The 30/90 Comfort Commitment
We won’t rest well until you do. Instead of just refunding your money if you’re unhappy, we’ll use 120 days to rebuild a custom mattress that works for you. And if we can’t, then we’ll refund you.
The Forever Partnership
Sometimes, warranties don’t cover what you need. From the date of purchase, we provide a partnership that ensures you’re satisfied. Forever.
Density Means Durability.
Ever seen a foam mattress with a big, body-shaped indent in it? That’s almost all because of the use of low density foams. But it’s not just the top layers of the mattress that need high density foam.
Oftentimes, mattress manufacturers will use quality, high-density foam in the top layer or two of a mattress (the parts you feel), then opt to use low-density, cheap foam in the base layer of the bed in order to cut costs. As a result, a cheap, low-density base is almost always to blame for body impressions, not the top layers. The foam simply isn’t made to last and will collapse with very little use.
1.5-1.8 lbs/ft³
(Most Foam Mattress Cores)
Nearly all bed-in-box mattresses found online use foam with a core density in this range, and most of those are closer to the low end of the range. They may feel the same as higher density foams because density does not equal firmness. They won’t always feel the same, though.
Over time, these foams will lose 35% of their firmness and 5% of their height.
In other words, they create body impressions and get softer faster than higher density foams. But they’re far less expensive, which makes them very attractive to other mattress retailers, who hardly ever even tell you the density of the foam they use.
2.8 lbs/ft³
(Comfort Option Foam Core)
Comfort Option uses foam with a 2.8 density, a level quality that is unmatched by our competition. This foam is nearly twice as dense, and in our internal tests, performs nearly 5x better than 1.5 density foams in terms of height loss.
Over time, our foam only loses less than 20% of its firmness and less than 3% of its height.
We’re transparent with the foam we use and call our products “Honestly Crafted” for that reason. We use the most quality foams in the industry and therefore are excited to offer as much information about our specifications as we can.
What is KülKōte?
An advanced phase change material that regulates your temperature as you sleep. Available on all Comfort Option® mattresses.
KülKōte is a Phase Change Material.
“Excellent quality, service, and responsiveness. Comfort Option is all American, and it’s all about customizability. I’m a side sleeper, and I was looking for a durable mattress that was soft enough not to make my shoulder go numb. I did it. And instead of trashing your mattress if you don’t like it, Meredith and the team will work with you to swap out layers of your mattress until it’s just right. When I got a different top layer, I couldn’t feel the Kulkote coating. I can feel it on their excellent pillow, though! When I expressed concern over this $300 upgrade to the top layer of the mattress, Meredith offered me a refund for it. Plus I get to keep the old top layer as well as the new Kulkote one. I can use the old one for camping, instead of it going to waste. Color me satisfied.”
