DCOOLAULTRA 14 Inch King Size Mattress - Medium Firm Hybrid with Memory Foam, Individually Wrapped Coils, CertiPUR-US Certified, Fiberglass-Free Design for Ultimate Comfort

Product Overview

This DCOOLAULTRA hybrid mattress measures 80 inches long by 76 inches wide with a 14-inch total thickness. It uses a combination of foam layers and individually wrapped coils in a medium-firm construction. The foam layers include gel memory foam and comfort foam designed for pressure distribution and contouring. High-density foam provides underlying support with a slightly firmer feel. The pocketed coil system features springs wrapped in individual fabric pockets to move independently. This design aims to reduce motion transfer and provide zoned support. Reinforced edge support enhances stability across the full sleep surface. The cover uses a finely woven breathable fabric to promote airflow and moisture release. An egg-crate foam layer creates air channels for continuous ventilation. All memory foam is CertiPUR-US certified and fiberglass-free. The mattress weighs 74 pounds and supports up to 500 pounds total weight. It ships compressed in a box and requires hand wash only for care. After unboxing, it needs up to 72 hours to fully expand to its intended shape. The manufacturer recommends keeping a safe distance during unwrapping as expansion can be rapid. This model is not customizable and comes as a complete mattress without additional components.

Design & Build

The DCOOLAULTRA hybrid mattress features a 14-inch profile with four distinct foam layers over a pocketed coil base. The top layers include gel-infused memory foam and comfort foam designed to contour to the body while distributing pressure. These foams are CertiPUR-US certified and fiberglass-free. Beneath them, high-density foam provides a firmer support layer that creates the medium-firm feel. The coil system uses individually wrapped springs in fabric pockets that move independently. This construction aims to reduce motion transfer and provide zoned support. Reinforced edges add stability to the perimeter. The cover is a finely woven breathable fabric that promotes airflow. An egg-crate foam layer beneath the cover creates air channels for ventilation. The mattress measures 80 by 76 inches in king size and weighs 74 pounds.

Care instructions specify hand washing only for maintenance. The mattress ships compressed in a box and expands rapidly upon unboxing. The manufacturer recommends keeping a safe distance during setup. It requires up to 72 hours to fully expand to its 14-inch height and intended shape. The design focuses on cooling with multiple ventilation features. The foam layers and coil system work together to limit excessive sinkage in the hips and lower back. This aims to support natural spinal alignment. The mattress is not customizable and comes as a complete unit. All materials are selected for durability and consistent performance over time.

Performance

The mattress combines foam contouring with coil responsiveness for a medium-firm sleep surface. The gel memory foam and comfort foam layers aim to distribute body weight evenly. This design targets pressure relief in shoulders, hips, and other contact points. The pocketed coil system provides support that adapts to different sleeping positions. Independent spring movement helps isolate motion so disturbances on one side are less likely to affect the other. Reinforced edges maintain stability when sitting or sleeping near the perimeter. The cooling features include breathable fabrics and air-channel foam to promote airflow. These elements work to reduce heat buildup and moisture retention during sleep.

The foam and coil construction limits excessive sinkage to help maintain spinal alignment. The medium-firm feel balances cushioning with support for various body types. The mattress supports up to 500 pounds total weight across its surface. After unboxing, the expansion process takes up to 72 hours for the foam to fully recover. The materials are designed for consistent performance night after night. The 10-year warranty provides coverage for manufacturing defects. The hybrid design aims to offer the contouring of foam with the responsiveness of coils in a value-oriented package.
