Evergreen® ecoRest™ mattresses blend organic latex and sustainable materials for eco-conscious comfort. Sleep cool and supported on this green mattress collection, made in Canada with nature-friendly design.
Meet the EVERGREEN™ 12" Medium‑Firm Organic Latex Foam Mattress—where natural materials and engineered airflow come together for cooler, cleaner, longer‑lasting comfort. A responsive organic latex comfort layer rests over an open‑cell bio foam core and latex support panel, balancing contouring pressure relief with sturdy alignment. Finished with an organic cotton quilt and backed by a 10‑year warranty, it delivers premium value made in Toronto.
Key Features
Open‑Cell Bio Foam Core: Engineered with a breathable open‑cell structure that enhances airflow and dissipates heat while providing a stable, buoyant base for consistent support across the sleep surface.
Organic Latex Comfort Layer: Naturally responsive latex contours to relieve pressure at shoulders and hips, springs back instantly to keep you lifted, and resists impressions for day‑one comfort night after night.
Organic Latex Support Panel: Adds targeted pushback beneath the comfort layer to maintain neutral spinal alignment, improving durability and support without the stiffness of conventional foams.
Organic Cotton Quilt: A naturally breathable cover woven from organic cotton wicks moisture and invites airflow, creating a clean sleep surface with a smooth, inviting hand feel.
Medium‑Firm Feel (12" Profile): Balanced firmness blends gentle contouring with sturdy support, ideal for back and combination sleepers seeking lift, alignment, and pressure relief in a robust 12‑inch build.
Motion‑Dampening Design: Buoyant latex and a stable core help isolate movement so partners sleep soundly, making late‑night turns and early wake‑ups less likely to ripple across the mattress.
Made in Toronto + 10‑Year Warranty: Locally crafted in Canada and backed by a decade of coverage, reflecting rigorous quality standards and long‑term value you can rely on, plus friendly local support when you need it.
Benefits
Cooler Night’s Sleep: Open‑cell bio foam and breathable organic fibers promote airflow and dissipate heat, helping maintain a more neutral temperature as seasons change and sleep cycles deepen.
Pressure Relief with Lift: Resilient organic latex cradles curves while keeping you elevated, easing tension in shoulders, hips, and lower back without the “stuck‑in” feel of softer foams.
Aligned, Supported Posture: A medium‑firm build encourages healthy spinal alignment for back and combination sleepers, helping reduce morning stiffness so you wake balanced and ready.
Cleaner, Fresher Sleep Surface: Organic latex and organic cotton create a simple, low‑odor sleep environment that stays fresh longer and resists sagging or lasting body impressions over time.
Reduced Partner Disturbance: The buoyant latex comfort layer and stable base work together to limit motion transfer, so one partner’s turns are less likely to ripple across the mattress.
Made Local, Built to Last: Canadian craftsmanship and durable materials deliver long‑term value, supported by a 10‑year warranty for reliable comfort you can count on—night after night and year after year.
Ideal For
Back & Combination Sleepers: A balanced medium‑firm feel keeps you lifted and aligned while allowing easy repositioning, making it a natural match if you rotate between back and side through the night.
Hot Sleepers Seeking Natural Materials: A breathable open‑cell core and organic fibers help disperse heat without gels or active cooling, ideal if you run warm and prefer simpler, nature‑derived construction.
Couples with Different Preferences: Motion‑dampening design and supportive feel offer a comfortable middle ground, minimizing disturbances even when sleep schedules and body types don’t perfectly match.
Value‑Focused Shoppers: Premium organic components, local craftsmanship, and a decade of warranty coverage deliver standout performance at a competitive price—without the luxury‑brand markup.
