How the Octave Horizon Mattress is Made
The Octave Horizon is seven layers of specialty foams and temperature control. Read on to learn how the mattress is constructed.
CryoFusion Cool-to-the-Touch Cover
The cover is cool to the touch and delightfully soft. Made from Octave’s proprietary CryoFusion nanofibers, it stays cool and keeps you comfortable. According to the Octave website, you can feel the coolness through the bed sheets. Plus, the cover is removable and machine washable.
Cooling CopperGel Memory Foam
A 2.5-inch memory foam layer offers pressure relief and temperature control. Antimicrobial CopperGel foam removes excess body heat. The middle part of the Octave Horizon mattress contains temperature regulating PolarMAX phase change material. Thanks to these materials, the memory foam won’t overheat as it molds to your body.
Breathable Latex Foam
Next is a 1.5-inch breathable layer of latex foam. Hundreds of air vents keep you cool while providing responsive support. This layer gives the Octave Horizon just enough bounce for a refreshing sleep.
ecoLuxe Conforming Gel Foam
A 2-inch layer of ecoLuxe gel foam continues the Octave Horizon cooling trend. This material cushions and conforms, providing a restful surface for tired joints. It cradles and provides pressure relief to your spine, hips and shoulders.
Responsive Elastex Foam
The Octave Horizon offers even more pressure relief with its responsive Elastex foam. This 2-inch transition layer offers additional bounce so that you can easily move around on the mattress. Whether you need to get out of bed or change sleep position, you won’t feel stuck.
Multi-Zone Support Foam
Finally, there’s a 6-inch layer of multi-zoned, high-density foam with air channels. The five zones target pressure relief to distribute weight and keep your spine properly aligned. The air channels are yet another cooling feature to keep you comfortable and dry.
Choose Your Mattress Size
Whether you sleep alone or with a spouse or partner, there’s an Octave Horizon mattress size for you:
- Twin: 38″ x 75″ x 14″
- Twin XL: 38″ x 80″ x 14″
- Full: 53″ x 75″ x 14″
- Queen: 60″ x 80″ x 14″
- King: 76″ x 80″ x 14″
- California King: 72″ x 84″ x 14″
- Split King: 38” x 80” x 14” (x2)
Medium-Firm Feel
The Octave Horizon has a rating of 6 on a firmness scale of 1 to 10, with 10 the firmest. That means it has a medium-firm feel that is suitable for most sleep positions. Medium-firm offers comfort and cushioning without letting you sink too low into the mattress. It’s also a great choice for couples who have differing sleep preferences.

Octave Horizon Mattress Review: Benefits and Any Drawbacks
We’ve done the research for you. Now we’ll share our opinion of the benefits and any drawbacks of the Octave Horizon mattress.
Top-to-Bottom Cooling Features
We’re impressed with the advanced cooling technology found in the Horizon. Most layers of this mattress contain some form of temperature control. It starts with the CryoFusion cover and CopperGel memory foam with PolarMAX phase change material. The two layers that are closest to your body draw away heat and feel cool to the touch.
And there more. We found breathable, heat-dissipating features in most layers of this mattress. From the breathable latex to the support foam with air channels, the Horizon keeps air circulating so you can keep your cool. If you tend to wake up in a sweat, the Octave Horizon may be a good choice.
Pressure Relief for Spine and Joints
The Octave Horizon mattress has several contouring layers that conform to your body and relieve pressure. Your tired joints will feel like they on a cloud, thanks to the CopperGel memory foam. A transition layer of Elastex foam provides enough bounce to let you move freely. In other words, you won’t feel trapped in the middle of the mattress when you get out of bed.
Your spine, hips and shoulders will appreciate the targeted pressure relief from the Multi-Zoned support foam. This base layer offers extra pressure relief to the areas that need it most, and helps keep the spine in a neutral position. When your spine and joints are properly aligned, you can rest comfortably and wake up without morning aches.
Motion Isolation
Thanks to its multiple foam layers and 14-inch thickness, the Horizon offers excellent motion isolation. On their website, Octave calls it “Zero Motion Transfer.” As the foam layers support and conform, they prevent motion from transferring from one side of the mattress to the other. Ideal for couples, motion isolation lets one partner sleep soundly, even if the other partner is tossing and turning or gets out of bed.
Machine Washable Cover
A clean and fresh mattress surface is essential for a restful sleep. Cleaning is easy because the Octave Horizon comes with a removable, machine washable cover. To refresh your mattress, just unzip the cover and toss it into the washing machine. It’s dryer-safe, too.
Made in Canada
You can be proud that the Octave Horizon is manufactured in Canada. Octave researches their products by gathering feedback from Canadian consumers. The result is a mattress that is designed made in Canada for the specific needs of Canadians.
Shipped In a Box
Convenience is always a plus, so we think you’ll like having your mattress shipped in a box to your door. The Octave Horizon is compressed, rolled and packed in a box. Even if you’re at work, the mattress will be waiting for you when you get home. There’s no need to meet with a delivery team or transport the mattress from a store showroom.
The boxed mattress is quite heavy, so you should have someone help you carry it indoors. The Octave Horizon expands to its full size in minutes, so it’s ready to use the same day you receive it.
Off-Gassing Odor
Like most foam mattresses in a box, the Horizon can produce an unpleasant, temporary odor after unboxing. Known as “off-gassing”, this odor is harmless but may bother some people. Off-gassing should wear off after about 24 hours in a well-ventilated space.
A Whole Year to Try It at Home
It’s not easy to know right away if a mattress is right for you. It can take at least a few weeks to adjust to a new sleep surface. That why we think you’ll like the generous 365- night sleep trial that comes with the Octave Horizon mattress. That gives you an entire year to literally sleep on it.
After a required 21-day break-in period, you can return the Octave Horizon during the 365-night trial. If the mattress just isn’t working for you, the company will schedule a pickup and issue a refund. If possible, Octave will donate the used mattress to a charity.
15-Year Warranty
You can rest easy knowing that your Octave Horizon mattress comes with a 15-year warranty. Coverage includes manufacturing defects and flaws that occur despite normal use. Octave will repair or replace a mattress that shows defects covered by the warranty.
A product warranty can change at any time, so make sure you’re aware of the latest terms. You can read the warranty terms on the Octave website.
Octave Horizon Mattress Review: Final Thoughts
The Canadian-made Octave Horizon mattress contains an innovative blend of foam layers that create a cool, comfortable sleep experience. From the washable cover to the Multi-Zone support foam, each layer adds pressure relief, support and temperature control.
The temperature control starts with the CryoFusion cover and continues with the CopperGel memory foam with PolarMAX phase change material. Unlike traditional memory foam, this layer won’t trap heat when it molds to your body. The Octave Horizon contains additional layers that draw away heat and permit air flow.
You’ll find pressure relief where you need it most, thanks to the Multi-Zone support foam. This layer works with the other foam layers to cradle and soothe your back, shoulders and joints. The contouring layers also provide excellent motion isolation, which promotes a restful, undisturbed sleep. The comfort and support of this medium-firm mattress is suitable for most sleep positions.
The 365-night sleep trial and 15-year warranty show that Octave stands by their Horizon mattress. Besides providing a generous trial period, the company donates the used mattresses to charity whenever possible.
