Memory Foam Mattress, Medium Firm, 10 in King - Cooling Comfort

Our review of this 10 in medium firm memory foam mattress finds it best suited to sleepers who want a balance of pressure relief and support. The mattress combines 3 in of gel memory foam over comfort and support layers, giving a cloud-like surface without feeling overly soft. It ships compressed in a box for easy setup and is covered in a breathable knitted fabric with a removable zipper cover, making it practical for bedrooms, guest rooms and dorms. Overall, the single biggest reason to consider this mattress is the blend of cooling gel comfort and medium firm support for a wide range of sleep positions.

Key Features

• Gel memory foam layer: 3 in of gel-infused memory foam contours to body curves and helps reduce pressure on shoulders, hips and spine for more comfortable sleep.
• Multi-layer support: 2 in of comfort support foam plus 5 in of flex comfort foam create a medium firm feel that aims to suit side, back and stomach sleepers.
• Certified safe materials: Uses CertiPUR-US certified foams and an OEKO-TEX Standard 100 cover to limit exposure to harmful chemicals.
• Breathable, removable cover: A premium knitted mattress cover with a bottom zipper increases airflow and can be removed for cleaning.
• Wave-shaped airflow layer: An internal wave support layer promotes ventilation through the core to help dissipate heat.
• Compressed in a box: Ships rolled and compressed for easy transport and fits through tight hallways and elevators.

Who It's For

This mattress is a solid option for couples and individual sleepers who want a medium firm surface that still provides pressure relief, especially for people who shift positions between side, back and stomach sleeping. The cooling gel and breathable cover make it attractive to those who sleep warm or live in moderate climates.

Lightweight sleepers who prefer very plush surfaces or heavy sleepers who need deep, targeted support may want to compare firmer or hybrid options. Shoppers who require an innerspring feel or edge reinforcement for heavy side seating should look elsewhere.
