EVERGREEN™ 12" Tight-Top Medium-Firm Organic Latex Mattress - King
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" Tight‑Top Medium‑Firm Organic Latex Mattress—handcrafted in Toronto to unite clean, breathable materials with precise, pressure‑relieving support. A buoyant organic latex comfort layer floats above 1,000 Hi‑Loft pocket coils, while an organic cotton–latex–wool quilt helps regulate temperature. Foam‑encased edges and Bio‑Foam supports add lasting stability and all‑night alignment.
Key Features
1,000 Hi‑Loft Pocket Coils: Individually wrapped coils respond to your body’s micro‑movements for targeted support, while limiting motion transfer across the bed so partners sleep soundly without roll‑together or bounce.
Foam‑Encased Perimeter: High‑density foam around the coil unit reinforces the edges, giving you a sturdier sit and maximizing the usable sleep surface, so you can spread out without that sliding‑off sensation.
Organic Latex Comfort Layer: Naturally buoyant and responsive, organic latex relieves pressure at shoulders and hips while maintaining uplifting support—so you feel weightless, not stuck, and turn easily through the night.
Organic Cotton, Latex & Wool Quilt: Breathable organic fibers wick moisture and help regulate temperature, creating a soft, cool‑to‑the‑touch sleep surface that stays fresh and comfortable across seasons.
Bio‑Foam Support Layers: Eco‑minded Bio‑Foam with natural content adds secondary cushioning and structural stability beneath the latex, supporting proper alignment and helping the mattress maintain its shape over time.
Medium‑Firm Tight‑Top Feel: A balanced, supportive feel that keeps your spine aligned while offering gentle contouring—ideal for back and stomach sleepers who want stability without sacrificing comfort.
Made in Toronto, Canada: Locally crafted for quality you can trust, with attentive materials sourcing and build oversight—backed by a dependable 10‑year warranty for confidence long after delivery.
Durable, Quiet Construction: The hybrid design pairs resilient latex with stabilized coils to reduce squeaks and sagging, delivering consistent, whisper‑quiet comfort and support year after year.
Benefits
Targeted Spinal Alignment: Precision pocket coils adapt under heavier areas while organic latex fills the gaps, promoting a neutral posture that can ease morning stiffness and keep you supported in every sleep position.
Cooler, Drier Sleep: The organic cotton–wool quilt and ventilated latex help dissipate body heat and humidity, creating a naturally breathable micro‑climate that stays comfortable through warm nights and cool seasons.
Motion‑Minimizing Design: Individually wrapped coils isolate movement so tossing, turning, or late‑night returns are less likely to ripple across the surface—great for light sleepers and couples with different schedules.
Edge‑to‑Edge Usable Space: Reinforced edges expand your sleeping area and provide stable sitting support, making it easier to get in and out of bed and maximizing comfort on smaller mattresses.
Lasting Performance: Resilient organic latex resists body impressions while a sturdy coil core maintains lift, so the mattress retains its feel and support for years with minimal maintenance.
Clean, Conscious Build: An organic fiber quilt, organic latex, and Bio‑Foam with natural content bring you comfort made from thoughtfully chosen materials—crafted close to home in Toronto.
Ideal For
Balanced‑Firmness Seekers: Sleepers who want a supportive, medium‑firm feel with gentle contouring—particularly back and stomach sleepers—will appreciate the lifted alignment and easy mobility of latex over pocket coils.
Hot Sleepers & Allergy‑Aware: Those who run warm or prefer natural top fabrics benefit from breathable organic cotton and wool plus open‑cell latex that helps regulate temperature and feels fresh night after night.
Motion‑Sensitive Couples: Partners with different schedules or tossing habits will love the way individually wrapped coils limit motion transfer, so each person enjoys deeper, less disturbed sleep.
Edge Sitters & Spread‑Out Sleepers: If you sit while dressing or like to use the full width of the mattress, the foam‑encased perimeter provides stable edges and maximizes comfort from corner to corner.
Eco‑Minded Shoppers: Buyers who value organic surface materials and a locally crafted product can rest easy knowing the EVERGREEN is made in Toronto with thoughtfully selected components and a 10‑year warranty.
