King Memory Foam Mattresses

King, 12"

This firm gel memory foam mattress delivers structured support with cooling comfort throughout the night. Gel-infused memory foam layers contour to the body's shape while helping to dissipate heat, creating a sleep surface that feels both supportive and comfortable. The firm feel promotes stability and alignment, making it a great option for those who prefer a more supportive mattress. A breathable design encourages airflow for enhanced comfort, while the smooth cover provides a clean, tailored finish. Plus, the responsive foam construction helps minimize motion transfer for more restful sleep.

This 12-inch medium memory foam mattress is designed to provide you with a cooler, more comfortable night's sleep. It features three layers of foam, including a top layer that helps regulate temperature and wicks away moisture. The middle layer offers adaptive support that conforms to your shape, distributing your weight evenly to relieve pressure points so you wake up feeling refreshed.

The mattress is very comfortable, when you lie down on it, you get the feeling that you are falling into a soft cloud. The packaging is very good. Of the minor disadvantages, there is an unpleasant smell due to packaging, but I think that it will disappear within a couple of days.. Daria. Newport Coast, CA. Fri May 06 2022

A step-up in the Essentials Collection, this Euro Pillow Top mattress features more Response Open Coils for adaptive support, additional layers of comfort foam, and a reinforced mattress edge for increased durability. It’s a great value mattress for a great night’s sleep with a soft feel.

It's an alright mattress for the guest room. I wanted this second guest room to have a plush mattress for guests who prefer that to the more firm one I already have. It's not the bed I would prefer, but it's fine for what I purchased it for. Now that we've had this mattress for a while, its way too soft and not comfortable for an adult.. Dawn. Cedar Falls, IA.

The mattress is beyond comfortable and fit perfectly in the new bed frame. I’m a stomach sleeper and this mattress is the best I’ve ever used. Highly recommended!. Maria. Salem, MA. Tue Apr 15 2025

The powers of springs and foam combined — for an update on our classic. We designed our own proprietary foam for our “just right” feel, and are now integrating those layers with resilient-yet-gentle springs. Responsive springs provide active support while Zoned Support foams treat your shoulders and hips differently for better spine alignment. Stay cool and asleep throughout the night thanks to airflow-friendly coils and breathable open-cell foams.

Just what I needed and very comfortable. Michael. Little Rock, AR. Thu Oct 05 2023
