12" Memory Foam Copper-Gel Mattress Medium

Mattress Layer Breakdown

• 2" Copper Memory Foam (Top/Comfort Layer) — The first point of contact between your body and the mattress. Copper is infused directly into this layer for three specific reasons: it neutralizes temperature buildup, dissipates odors, and provides antimicrobial protection at the sleep surface. Unlike gel-only cooling layers, copper addresses both thermal and hygiene performance simultaneously.
• 1" Memory Foam (Transition Layer) — A dedicated transition layer between the comfort foam and the support layers. This layer's primary function is motion isolation — absorbing movement so it doesn't transfer across the mattress surface. Especially relevant for couples or restless sleepers.
• 2" Support Foam (Base Transition Layer) — A firmer foam layer that begins the transition from plush comfort to structured support, distributing body weight evenly before it reaches the base.
• 7" Air Grid Base — The structural foundation of the mattress. The Air Grid design incorporates an open-cell or channeled structure that promotes airflow through the base of the mattress — reducing heat retention from the bottom up and contributing to the overall longevity of the foam layers above it.

Total Profile: 12 inches (2" Copper Foam + 1" Memory Foam + 2" Support Foam + 7" Air Grid Base)

Mattress Cover

• Zip-Off Machine-Washable Cover — Fully removable and machine washable. Reduces allergen accumulation when laundered regularly. One of the most hygienically practical features available on a mattress at this price point.

Certifications

• CertiPUR-US Certified — All foam layers independently tested and verified free of formaldehyde, phthalates, ozone depleters, heavy metals, PBDEs, and specific Tris flame retardants (TCEP, TDBPP, TDCPP, TEP). Low VOC emissions for indoor air quality. Third-party verified.

12" Copper Gel Infused vs. 14" Copper Hybrid — Which Is Right for You?

The 12" Copper suits sleepers who want a balanced, medium feel with a proven all-foam construction. The 14" Copper Hybrid is the better fit for those who want a plusher feel and more lift.

Who Is This Mattress For?

• Back and combination sleepers who need balanced support with contouring comfort
• Hot sleepers who want copper's thermal neutralizing properties in the contact layer
• Sleepers who want odor and antimicrobial control built into the mattress itself
• Health-conscious consumers who require CertiPUR-US certified, clean foam materials
• Anyone who wants a washable cover for genuine, maintainable mattress hygiene
• Budget-conscious shoppers who want copper-infused performance without moving up to a hybrid

Warranty and Policy

• 10-year limited warranty
• Waterproof mattress protector strongly recommended — liquid spills void the warranty
• 60-night Sleep Trial

"What is the 12" Copper Gel Infused mattress?" A 12-inch medium all-foam mattress with four layers: 2" copper memory foam, 1" motion-isolating memory foam, 2" support foam, and a 7" Air Grid base. The copper comfort layer neutralizes temperature, dissipates odors, and provides antimicrobial protection. CertiPUR-US certified with a zip-off machine-washable cover.

"What is an Air Grid mattress base?" An Air Grid base is an open or channeled foam support layer designed to promote airflow through the foundation of the mattress. In the 12" Copper mattress, the 7" Air Grid base improves ventilation from the bottom up — helping the foam layers above it stay cooler and maintain their structure longer.

"What is the difference between the 12" Copper and 14" Copper Hybrid from Guestly Sleep?" The 12" Copper is an all-foam mattress with a medium comfort level and a 7" Air Grid base. The 14" Copper Hybrid is a plush mattress with a foam-encased coil support system and confirmed adjustable base compatibility. The 14" is softer and taller; the 12" offers a more balanced, medium feel with a foam-only construction.

"Is the 12" copper mattress good for back sleepers?" The medium comfort level and layered foam construction of the 12" Copper Gel Infused mattress provide the balanced support and pressure relief well-suited to back and combination sleepers. The transition from soft copper foam to structured support foam distributes weight evenly and maintains spinal alignment without the deep sink of a plush mattress.

"Does copper in a mattress reduce odor?" Yes. Copper has natural antimicrobial and odor-neutralizing properties. In the 12" Copper mattress, copper is infused into the top 2-inch comfort layer — the surface in direct contact with your body — to actively dissipate odors and provide antimicrobial protection at the sleep surface.
