Delivery, Sleep Trial & Returns

Octave ships directly to your door using FedEx. Your mattress will ship anywhere in Canada from Ontario or Alberta, although additional fees may apply for some remote locations. You should receive your mattress in 3–10 business days.

Your mattress arrives in a cardboard box and is wrapped in two layers of heavy-duty plastic for added protection. Once unrolled, Octave Horizon expands to its full 14″ height in a couple of minutes. It’s ready to sleep on the same day it’s delivered.

Octave’s 365-night sleep trial is among the longest in Canada, with industry-standard trials being just 100 nights. The company also arranges to pick up returns for free within the sleep trial period. They’ll issue a full refund if you aren’t satisfied with your purchase.

Octave Horizon Mattress Construction

HeightLayersCertiPUR-US® CertifiedMachine Washable Cover





The Canadian-made Octave Horizon is the most advanced memory foam mattress in the Octave collection. It made with 5 layers of specialty memory foam and has a tall 14″ profile to provide as much pressure relief and motion isolation as possible.

  • Layer 1: Octave Horizon’s comfort layer is 2.5″ of CopperGel™ memory foam. This layer is infused with PolarMAX® phase-change material, which reacts to your changing skin temperature to keep your body comfortable. Copper is also an antimicrobial metal and is meant to promote cleanliness in the mattress’s top layer.
  • Layer 2: Octave Horizon has a 1.5″ layer of aerated latex. This responsive material contains hundreds of air vents, which allow for high ventilation and temperature control while still offering plenty of support.
  • Layer 3: This layer is 2″ of ecoLuxe® cooling gel foam. It contours around your hips, back, and shoulders to relieve pressure points and absorb heat from the upper mattress layers.
  • Layer 4: The mattress’s transition layer is 2″ of premium Elastex® foam. This proprietary material feels just like natural body-cushioning latex. It also adds extra bounce that helps you change positions more easily.
  • Layer 5: Octave Horizon’s support layer is 6″ of high-density support foam. It has five pressure-relief zones to keep your spine aligned and your weight evenly distributed. The foam also includes air channels for extra-cooling airflow.

Octave Horizon has a soft-touch cover that features CryoFusion™ cooling nanofibres. In fact, it has even more cooling nanofibres than Octave Mirage and Octave Vista. This makes the mattress cool enough to feel through your sheets. The top cover is also machine washable for extra convenience.

Company Background

LaunchedCompany HQOwnershipBBB RatingTrustpilot Rating






Octave is the next step in the evolution of Novosbed, one of Canada’s first bed-in-a-box brands. Founded in 2009, Novosbed was the first company to offer a 100-night sleep trial, which was later extended to 365 nights. Octave has applied this deep experience and history of innovation to develop Canada’s best cooling mattress.

Octave Vista, Mirage, and Horizon are are designed with advanced cooling features like temperature-regulating fabrics, copper-infused memory foam to dissipate heat, and phase-change material for temperature balance. Octave also offers exceptional motion isolation and pressure relief, resulting in an even greater sleep experience than Novosbed.

  • Octave Vista provides an intensely cooling sleep experience with a CryoFusion™ cooling nanofibre cover, copper-infused memory foam treated with PolarMAX® phase-change material for temperature balance, and multi-zone support foam with air channels for breathability and temperature control.
  • Octave Mirage builds on Vista’s advanced features with an additional layer of aerated latex foam, which is filled with hundreds of vents for improved cooling and breathability.
  • Octave Horizon provides the ultimate cooling experience with an added layer of ecoLuxe® cooling gel foam, which cushions and conforms to your body for your most comfortable night’s sleep ever.

Great bed!!! So comfortable and I sleep throughout the night now.

Whitney G.
Verified Novosbed Buyer (previous version of Octave)

I sleep much deeper and more restfully. I also don’t have back pain anymore which has been a chronic problem for quite some time. Best decision I made!

Katelyn F.
Verified Novosbed Buyer (previous version of Octave)

I can sleep on my side, stomach and back and I am comfy no matter what.

Teigen B.
Verified Novosbed Buyer (previous version of Octave)

I’ve spent twice as much in the past for mattresses that didn’t feel as nice as this one.

Betsy H.
Verified Novosbed Buyer (previous version of Octave)

From the moment my head hit the pillow I slept straight through the night and straight through my alarm which I’ve never done before. Highly recommended for anyone who wants a good night sleep!

Frequently Asked Questions

Is the Octave mattress cover machine washable?

Yes. Remove the top cover using the 360° zipper and run it through your washing machine on a gentle cycle. Then lay it out to air-dry, or run a low-heat or tumble-dry cycle in the dryer. You can reattach the clean, dry cover in seconds using the zipper.

What does the Octave warranty cover?

The 15-year Octave mattress warranty covers repair or replacement in case of manufacturer errors.

What happens to returned Octave mattresses?

Returned Octave mattresses are donated to nearby community organizations or picked up by a local recycling partner, depending on regional restrictions.

Where is the Octave Horizon mattress made?

Octave Horizon is made in Canada, with manufacturing facilities in Ontario.

Does the Octave Horizon mattress need a special frame?

Your Octave Horizon can use any supportive, untreated foundation, such as a solid box foundation, slatted base, or adjustable bed. Foam mattresses are heavier than innerspring and hybrid mattresses, so be sure your bed frame is sturdy enough to handle the extra weight. Octave sells compatible mattress foundations if you need one.

Is Octave Horizon eco-conscious?

Octave’s mattress cover and layers were independently tested to make sure they’re safe and eco-conscious.

  • The top cover fabric was independently tested for harmful substances according to STANDARD 100 by OEKO-TEX® (SH025 194423).
  • Each foam layer is CertiPUR-US® certified, meaning it meets high standards for emissions, content, performance, and durability.
How much does the Octave Horizon mattress cost?

Octave Horizon pricing ranges from $1,199 to $1,699, depending on the size you choose. A queen-size Octave Horizon is available for $1,499.

What makes Octave Horizon different from Octave Vista?

Horizon is the best Octave mattress available and comes at a higher price than the entry-level Octave Vista.

Octave Horizon has five premium foam layers, including a 1.5″ layer of aerated latex foam and a 2″ layer of ecoLuxe® cooling gel foam for extra cooling and more comfort. Its thicker foam layers and increased height provide enhanced pressure relief and motion isolation.

Although Octave Vista is an impressive entry-level model and will suit a wide range of sleepers, it has fewer layers of premium foam and cooling features.

What makes Octave Horizon different from Octave Mirage?

As Octave’s mid-level mattress, Mirage offers advanced cooling, pressure-point relief, and motion isolation features. But only Octave Horizon contains 2″ of ecoLuxe® cooling gel foam. This foam layer conforms to your body for extra-supportive cooling.

Octave Horizon also has more cooling nanofibres in the top cover, making the mattress noticeably cool to the touch—and well worth the investment.
