EGOHOME 12 Inch King Size Mattress - Cooling Copper Gel Memory Foam

Our review of the EGOHOME 12 Inch King Size Mattress finds it best for sleepers seeking a medium-feel all-foam bed that balances pressure relief and cooling. The single biggest reason to consider this mattress is its combination of copper-infused memory foam and a graphene-infused cover, which work together to manage heat and moisture so sleepers wake up feeling fresher and less achy. This mattress-in-a-box is practical to set up and backed by a 10-year warranty, making it a sensible choice for those who want a breathable, supportive mattress without fiberglass in the foam.

Key Features

• Medium feel: The mattress offers a balanced medium firmness that supports multiple sleep positions while relieving pressure on hips and shoulders.
• Copper gel memory foam: Copper-infused foam helps regulate temperature and moisture, contributing to a drier, more comfortable night.
• Graphene-infused cover: The cover improves thermal dispersion and wicks moisture away from the body for a cooler sleep surface.
• Fiberglass-free construction: The foam is manufactured without fiberglass, allowing for a safer, longer-lasting foam core.
• Mattress-in-a-box delivery: Arrives compressed and rolled for easy setup at home, expanding to full shape within hours.
• 10-year warranty: A decade of coverage provides reassurance against manufacturing defects and delivery damage.

Who It's For

The mattress is well suited to couples and individual sleepers who prefer a medium mattress that adapts to back, side, and stomach sleeping. People who run warm at night or sweat are likely to appreciate the combined copper gel and graphene technologies that target heat and moisture management.

It may be less appropriate for those who want a very plush, pillow-top feel or an innerspring bounce. Shoppers seeking a trial-return period should note there is no trial and opened mattresses cannot be returned, so buyers should be confident before unboxing.

Pros & Cons

Pros

• Comfortable medium support that suits multiple sleep positions and reduces morning aches.
• Effective cooling approach using both copper-infused foam and a graphene cover to limit heat buildup.
• Fiberglass-free memory foam construction offers a safer foam experience and solid build quality.
• Convenient compressed delivery and a 10-year warranty for long-term peace of mind.

Cons

• No trial period and opened mattresses are not returnable, so initial odor or fit issues are the buyer's responsibility.
• All-foam design lacks the bounce of innerspring or hybrid mattresses, which some sleepers prefer.
