Posturepedic Optimum

Posturepedic Series Optimum


Hot is a compliment...unless you're a foam mattress. One of the biggest complaints about other foam mattresses is that they tend to sleep hot. Optimum™ featuring OUTLAST® technology is different. Optimum is designed to help keep you in the optimum temperature range that’s scientifically proven to deliver a deep, relaxing sleep.

Optimum Temperature

A mattress unlike anything else – that's cool

Optimum™ mattresses feature OptiCool™* gel memory foam that provides a refreshing coolness like the cool side of the pillow. OptiCool™ that is fused with OUTLAST®* is proven to be more effective for removing excess heat during the night.

OUTLAST® material is used in high-performance outdoor gear, undergarments, and even footwear for superior temperature regulation. So how much more effective is OptiCool™ gel memory foam at removing excess heat? 12 times more effective than standard memory foam or other gel memory foams.

Optimum Comfort

Responds to your weight and temperature

Body-hugging OptiCool® Gel Memory Foam and our proprietary gel OptiCore™ combine tocreate a feeling of enveloped comfort with stable support.

Optimum Support

Sealy Posturepedic CoreSupport where you need it most

Sealy Posturepedic’s patented OptiCore™ with Core Support is designed specifically to deliver support that’s a cut above other memory foam mattresses. The CoreSupport Center is a center-third lumbar support layer that sits directly underneath the high density foam layer for optimum support where you need it most.

Beneath the CoreSupport Center is our patented OptiCore™, a firmer section at the bottom of the mattress, which provides a deeper level of support.

The OptiCore Plus provides an even deeper level of support with the addition of the PostureLok Edge, a foam perimeter edge system that reinforces the mattress so you can sleep comfortably anywhere on the mattress surface and enjoy a solid seating edge*.

The Gel OptiCore is our proprietary layer of firmer, higher-density gel foam is designed to provide a feeling of deep support to allow you to sleep soundly throughout the night and wake up feeling refreshed*.

* In select models only.

Made in North America

Comfort Levels

Finding the right top cushioning is a matter of personal taste. That’s why Sealy offers a wide range of surface feels or comfort choices. Each one designed to provide a consistent level of support throughout the mattress.

To begin your search, here are some of the basic differences:

Firm: For customers who want a stiff surface support with just a hint of softness for comfort.

Cushion Firm: For customers who want a substantial surface support with quilted softness for comfort.

Plush: For customers who are looking for a soft, cushioning surface with deep support.

Ultra Plush: For customers who are looking for an enveloping softness with deep support.


Caring for your Sealy.

Your Sealy mattress is designed to last a long, long time. That said, there are things you can do to keep it looking and feeling great. Keeping it clean, for starters. It’s highly recommended that you use a mattress pad. And while spills happen, try and keep it free of water or other liquids.

Give it time to “air” after removing it from the plastic packaging. That new mattress smell will dissipate quickly. Use a proper frame with center support. For king and queen size mattresses, this ensures your warranty will remain in effect. Don’t flip the mattress. A Sealy mattress has comfort layers on one side. It should, however be rotated on occasion to minimize body impressions in the upholstery layers.

Cleaning your Sealy.

If you’re the obsessively-clean type and want to go further than a mattress pad, vacuuming is the only other recommended way to keep your Sealy mattress in pristine condition. For stains, use mild soap with cold water and apply lightly. Soaking the mattress or foundation, using dry-cleaning fluid of any type isn’t a good idea. They can damage the comfort and upholstery materials. And we don’t want that, do we? In short, show your Sealy a little love and it will return the favor.


That mattress you were just looking at? It’ll look and feel the same way for a long time. Since 1881, Sealy has been aiming for perfection by using durable, quality materials and the most rigorous testing standards in the industry. See your local retailer and refer to the warranty card attached to the mattress for more details.
