12" Ecocore Hybrid Mattress-Medium Plush
12" Ecocore Hybrid Mattress-Medium Plush
- 2" Bio-Based Air Foam — Open-celled memory foam derived from soy, a renewable resource. The bio-based composition reduces reliance on petroleum-based foam without sacrificing performance. Open-cell structure promotes airflow and breathability for a temperature-neutral sleep surface — naturally cool without requiring gel infusion at this layer.
- 2" Plush Gel-Infused Memory Foam — A dedicated gel comfort layer that conforms closely to the body for pressure relief while the gel disperses heat that builds up in the foam during sleep. This layer is where the plush feel is concentrated — soft, enveloping, and cooling.
- Patented Edge Support System — A perimeter support structure that reinforces the edges of the mattress, making the full sleeping surface usable rather than just the center. Delivers 20% more sleeping surface compared to mattresses without edge support — a meaningful difference for couples, larger sleepers, or anyone who uses the full width of their bed.
- 1" Transition Foam — High-density foam that bridges the comfort layers above and the coil system below, preventing the feeling of "falling through" to the coils while maintaining smooth weight distribution.
- 6" Edge-to-Edge Pocketed Coils — Individually wrapped coils that run the full width of the mattress from edge to edge. Each coil responds independently, reducing motion transfer between sleep partners and improving airflow through the support core — a key reason hybrid mattresses sleep cooler than all-foam alternatives.
- 1" Base Foam — A foundational support layer beneath the coils that stabilizes the mattress and provides additional structural integrity.
Total Profile: 12 inches (2" Bio-Based Air Foam + 2" Gel Memory Foam + 1" Transition Foam + 6" Pocketed Coils + 1" Base Foam)
- Zip-Off Machine-Washable Cooling Cover — Fully removable and machine washable. Reduces allergen accumulation when laundered regularly. Standard on all Guestly Sleep mattresses with washable covers — not a premium add-on.
- CertiPUR-US Certified — All foam layers independently tested and verified free of formaldehyde, phthalates, ozone depleters, heavy metals, PBDEs, and specific Tris flame retardants. Low VOC emissions for indoor air quality. Third-party verified.

"What is the 12" EcoCore Hybrid Deluxe mattress?" A 12-inch medium plush hybrid mattress with six layers including bio-based soy air foam, plush gel-infused memory foam, a patented edge support system, and 6-inch edge-to-edge pocketed coils. CertiPUR-US certified, with a zip-off machine-washable cooling cover. Offers 20% more sleeping surface than mattresses without edge support.
"What does a patented edge support system do in a mattress?" An edge support system reinforces the perimeter of a mattress so the sleeping surface remains supportive all the way to the edges — not just in the center. The EcoCore Hybrid Deluxe's patented edge support provides 20% more usable sleeping surface compared to mattresses without it, which is especially beneficial for couples sharing a bed or sleepers who use the full width of their mattress.
"Is the EcoCore Hybrid Deluxe good for couples?" Yes. The 12" EcoCore Hybrid Deluxe combines two features that directly benefit couples: individually wrapped pocketed coils that isolate motion so one partner's movement doesn't disturb the other, and a patented edge support system that expands the usable sleeping surface by 20% — meaning both partners have full, supported access to the mattress width.
"What is the most eco-friendly mattress from Guestly Sleep?" The 12" EcoCore Hybrid Deluxe is the only mattress in the Guestly Sleep lineup made with bio-based soy foam — an open-celled, plant-derived foam layer that replaces a portion of petroleum content with renewable soy oil. It is CertiPUR-US certified and hypoallergenic.
