LET’S GET THE FEEL RIGHT
Harmoni brings surface cushioning and strong underlying support together. Its responsive latex and pocket-coil construction suit sleepers who like to feel held up while enjoying a comfortable layer of give.
A medium-firm to firm feel makes Harmoni worth exploring if you sleep on your back or stomach, or if you are a side sleeper who wants a firmer, more lifted surface. Cooling comfort layers add cushioning without a deeply enveloping sensation.
Talalay latex and individually pocketed coils respond as you turn. A lively hybrid feel helps you change positions comfortably while the support system stays with you.
Harmoni offers cushioning with a firmer surface. If you prefer more contouring around your shoulders and hips, especially on your side, explore Tranquiliti’s enhanced cushioning or Sereniti’s deeper comfort.
A new mattress starts tighter. Average break-in is around 60 days; individual experiences vary. This is comfort guidance, separate from the trial’s 30-night minimum-use requirement.
COMFORT ABOVE. SUPPORT BELOW.
Organic cotton, cooling comfort layers, and Talalay latex work together above individually pocketed coils. Each layer contributes to Harmoni’s responsive, comfortably lifted feel.
GOTS-certified organic cotton fabric finishes the top with a breathable feel and the flowing knit pattern of our new cover.
One inch of cooling gel-infused foam adds gentle cushioning beneath the cover. This CertiPUR-US® certified foam is tested for low VOC emissions.
One inch of Talalay latex adds responsive cushioning. Beneath it, one inch of latex-blend, copper-infused comfort foam complements the feel. The CertiPUR-US® certified foam is tested for low VOC emissions.
A half-inch of soybean-oil transition foam bridges the comfort layers and support system. This CertiPUR-US® certified foam is tested for low VOC emissions.
A seven-inch pocket-coil system provides responsive support. Individually fabric-wrapped coils work alongside extra-firm Quantum Edge support around the perimeter.
One inch of soybean-oil base foam supports the coil unit. This CertiPUR-US® certified foam is tested for low VOC emissions. Blue channel-stitched chenille completes the border.

Check your foundation, plan for the height, and understand the trial before you bring Harmoni home.
Harmoni is compatible with adjustable bases and properly supported rigid platforms. Slats should be at least 2 inches wide with gaps no greater than 2 inches. Queen and larger beds need proper center support.
Foundation & warranty detailsThe finished profile is approximately 12.5 inches. Check the combined height of your mattress and base, and choose sheets with enough pocket depth for a comfortable fit.
Cooling gel-infused foam, breathable Talalay latex, and an open coil chamber support airflow. Choose Harmoni for its responsive cushioning and firmer feel; temperature experiences vary with bedding and the sleeper.
Harmoni is worth exploring when both sleepers enjoy a firmer, responsive surface. If one person wants more cushioning, our quiz considers each partner separately and customer support can help you compare the tradeoffs.
Explore your individual matchesUse a waterproof mattress protector from the first night (it's required for a return) and spot-clean sparingly with mild soap and water. Let it dry completely. Do not remove the cover or flip the mattress.
For even wear, we recommend rotating 180° monthly for the first six months, then every six months. Missing a rotation does not void warranty coverage.
The 90-night trial requires at least 30 nights actually slept on the mattress before a standard return. A mattress protector is required for a return; it must be on the mattress from the first night you sleep on it. Returns involve condition checks and deductions. Exchanges are final sale with no new trial.
