-
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.
-
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 35 IFD (which is the measurement of firmness) provides a medium-soft feel. It also utilizes a unique I-Beam CNC profile to add pressure relief and additional air flow, ensuring long-lasting, cooling comfort.

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.
Make it stand out
Whatever it is, the way you tell your story online can make all the difference.
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.
KülKōte is a water-based, polymer coating that uses micro-capsules that continually changes phases from liquid to solid in order to effectively manage heat energy. We spray it right onto the surface of the foam on the top layer of our mattresses, along with the surface of our SoftFlo® pillows.
“Absolutely LOVE our mattress! We chose Comfort Option because of the versatility in the mattress options but we were pleasantly surprised by how wonderful our experience was with the customer service team! They promptly answered our initial questions during the buying process, quickly worked to fix an issue we had with our delivery, and made time to follow up with us to make sure our new mattress was to our liking. I would recommend this brand to anyone on the market for a new mattress and you are tired of dealing with big box stores.”
