Product Overview

The Beautyrest Black Series Three is a hybrid mattress measuring 79.5 inches long, 76 inches wide, and 14.25 inches thick in the King size, weighing 166.2 pounds. It features an 8-layer construction with an extra-firm feel, described as having a pillow-top style in black color. The mattress uses triple-stranded pocketed coil technology for motion separation and support, topped with cooling yarn and cashmere woven into the surface to help transfer heat away from the body. A layer of specialized foam is quilted into the sleep surface for immediate pressure relief, while a premium memory foam layer infused with diamond particles aids in heat dissipation. A ventilated latex layer maximizes airflow and provides responsive contouring. Additional features include breathability, edge support, low motion transfer, pressure relief, and temperature regulation, with benefits aimed at improving sleep and reducing toss and turn. It is not customizable, portable, or foldable, and is designed for adult use. Care and maintenance should follow manufacturer guidelines, and its substantial weight may require professional setup assistance.

Design & Build

The Beautyrest Black Series Three mattress features an 8-layer hybrid construction with a black pillow-top style, measuring 14.25 inches in thickness. Its core uses triple-stranded pocketed coils, which are designed to offer individualized support and excellent motion separation, reducing disturbance from a partner's movements. The surface incorporates cooling yarn and cashmere, woven to help transfer heat away from the body, topped with a layer of specialized foam quilted in for immediate pressure relief. A premium memory foam layer infused with diamond particles further aids in cooling, while a ventilated latex layer enhances airflow and contouring. The mattress is extra-firm, providing a solid sleep surface with edge support, and is built with breathable materials to regulate temperature. Cleaning and maintenance should be done according to manufacturer instructions, and its non-portable, non-foldable design requires careful handling during setup due to its 166.2-pound weight.

Aesthetically, the mattress has a sleek black color with a pillow-top finish, adding a touch of luxury to bedroom decor. The design focuses on durability with reinforced edges and high-quality materials, though some reviewers report issues with sagging over time. The construction includes multiple layers aimed at combining support and comfort, with the pocketed coils providing a responsive base and the foam layers offering cushioning. The mattress is not customizable, so users must rely on the preset extra-firm feel. Its hybrid nature balances the bounce of coils with the contouring of foam, intended for long-term use, but user experiences vary regarding its resilience. Proper care, such as using a mattress protector and rotating periodically, may help maintain its condition, though the warranty covers defects for 10 years.

Performance

In terms of performance, the Beautyrest Black Series Three mattress aims to deliver firm support with advanced cooling and pressure relief. The triple-stranded pocketed coils provide individualized support and low motion transfer, which many users appreciate for undisturbed sleep. The cooling technologies, including the yarn and cashmere surface and diamond-infused memory foam, help regulate temperature, reducing heat buildup during the night. The ventilated latex layer enhances airflow, contributing to a cooler sleep environment. Reviewers who had positive experiences note immediate comfort and improved sleep quality, with some calling it the best mattress they've ever had. The extra-firm feel offers solid support for back and stomach sleepers, and the pressure relief features reduce discomfort in pressure points. However, performance consistency varies, with some users reporting excellent results and others experiencing issues.

Durability and long-term performance are mixed among reviewers. Some report that the mattress developed sagging or body pits within weeks, leading to discomfort and a decline in support over time. These users found it less durable than expected, with one noting it became painful to sleep on in less than a year. The hybrid construction may not hold up well under certain conditions, and the firmness might soften unevenly. Trade-offs include the mattress's heavy weight, which makes moving and setup challenging, and its non-portable design limits flexibility. While it offers benefits like breathability and edge support, the variability in user experiences suggests that performance may depend on individual usage and body types. The 100-night sleep trial allows users to test it, but returns can be cumbersome due to size and weight.
