VISCOSOFT GETS AROUND
We fix everyone else's mattresses. So we made one that doesn't need fixing.
We get it. This is a big, expensive decision.
Mattresses aren't cheap. Comfort is personal. Mess it up and you're out the money, stuck sleeping on a mistake every night.
We didn't build this mattress to ignore that risk. We built it because we’re experts in toppers, which exist for one reason: mattresses fail in the same spot, over and over. Solid base, comfort layer gives out early. We've watched that happen enough times that we decided to just fix it at the source. That's Edge.
Meet the Replaceable Comfort Layer
You don't rebuild the house when the roof wears out
At the heart of every Edge Signature is a 3.5" comfort layer, fully separate from the structural foundation beneath it. Did you know that roughly 90% of a mattress's wear happens right there, in the top few inches absorbing your weight every night, while the foundation underneath is usually still doing its job?
We designed Edge so that when it's time for a change (whether the comfort worn down, or preferences shifted), you simply swap in a new Replacement Comfort Layer, while the rest of the mattress is still good to go.

The right feel isn't universal, that’s why we created two comfort options, so you can choose what’s best for you.
You know your body better than we do
Comfort, Chosen By You
-
Plush
A cushioned, close-contouring feel. The comfort layer wraps around your shoulders and hips for soft, pressure-relieving support.
BEST FOR SIDE SLEEPERS • LIGHTER FRAMES • HIP/SHOULDER PAIN
-
Medium-Firm
A balanced, supportive feel. The most popular of the two, with just enough give to cradle your body and let the foam respond where you need it most.
BEST FOR BACK, STOMACH + COMBO SLEEPERS • MORE SUPPORT • BACK PAIN
The Edge Signature is built to adapt with you as lifestyle changes, one comfort layer at a time. It's modular nature lets you sleep comfortably throughout all of life's curveballs.
Your needs evolve, your mattress should evolve with them

The one part of your mattress that's not supposed to change
A Strong Foundation
Beneath the comfort layer, a stabilizing transition zone and dense support core keep the Edge aligned night after night. While mass-market foam mattresses soften unevenly over time, Edge is engineered to preserve its lift and structure well beyond the "new mattress" phase.
-
Support that reaches to the very Edge

Reinforced perimeter construction keeps the edge of your Edge (pun intended) as stable as the center. More usable surface, less roll-off, and support that holds even when you sit down at the edge of the bed.
-
Built to move heat, not trap it

Gel-infused foam and a breathable knit cover work together to pull heat away from your body throughout the night, keeping the surface consistently cool no matter the season.
-
Premium shouldn't mean high-maintenance
![A woman unzipping a removable, machine washable mattress cover]()
![A woman unzipping a removable, machine washable mattress cover]()
A fully removable, machine-washable cover locks the Replacement Comfort Layer securely in place. Far easier to maintain than a mattress you could never really wash.
