Optimum Radiance

The Radiance is a mattress in the Sealy Optimum collection. It is just above the entry level Destiny. Like all Optimum models, Radiance features three "Opti" foams: OptiCool, OptiSense and Opticore.

The quilted cover of the Optimum Radiance mattress includes fire resistant fibers. directly under this cover is a 2" layer of OptiCool, a Sealy formulation of gel memory foam. This is memory foam which is infused with gel, which is added to enhance the supportive and contouring properties of the memory foam. The gel is also there to cool the sleeping surface. Gel absorbs body heat and carries it away to where it can dissipate.

Not only that, but the gel memory foam in OptiCool is fused with Outlast, a material developed for the space program to keep the temperatures of a spacesuit within a desired range. Outlast contains Phase Change Materials (PCMs). When it gets too hot, PCMs liquify, absorbing heat. When it is too cool, PCMs solidify, releasing heat.

Below the OptiCool in the Sealy Optimum Radiance is 2" of OptiSense. This is another form of memory foam. It is very conforming, helping the Radiance to match the shape of a sleeper's body. This distributes support evenly along the entire body, so that a few prominent body parts do not bear the whole burden. One important benefit of this is reduction or elimination of pressure points. An early, and continuing, use of memory foam is in medical mattresses to prevent bed sores.

Since memory foam is so conformable, there is the tendency to sag, hence the need for reliable underlying support. In the Sealy Optimum Radiance this support is provided by a 6" base support layer of Opticore. This is a high density, high ILD foam developed by Sealy. It takes the place of the coils of innerspring mattresses. The Opticore allows the Optimum Radiance mattress to offer orthopedic support, even while being conforming.

The two recommened foundations for Sealy Optimum Radiance mattresses are the Optimum™ Foundation and the Optimum™ Reflexion® Powerbase. The Optimum™ Foundation has been especially engineered to fully support foam mattresses, such as those in the Optimum collection. And Optimum Radiance models, like most foam mattresses, are compatible with adjustable bases such as the Optimum™ Reflexion® Powerbase.

The Optimum Radiance is widely available, along with other Sealy mattresses, across the country in stores and online. This includes department stores as well as furniture and bedding outlets. The Sealy Optimum Radiance carries a 25-year limited warranty. There is also a 120-day sleep trial period.
