Simmons Beautyrest Centennial 13" Altar Firm Tight Top Mattress

Experience advanced firm support with the Simmons Beautyrest Centennial 13" Altar Firm Tight Top Mattress. Designed for sleepers who prefer a more supportive, stable sleep surface, the Altar combines Beautyrest’s most advanced pocketed coil technology with responsive latex, pressure-relieving memory foam, and cooling materials for a premium sleep experience.

With its 13-inch profile, firm comfort feel, advanced motion separation, and Canadian-made construction, the Altar is a strong choice for back sleepers, stomach sleepers, couples, and anyone looking for luxury-level support without a plush pillow-top feel.

Triple-Stranded Pocketed Coil® Technology

At the core of the Altar is Beautyrest’s exclusive Triple-Stranded Pocketed Coil® Technology.

This advanced coil system is designed to provide highly individualized support by allowing the mattress to respond independently to different areas of the body.

Because the coils move separately, they also help reduce motion transfer across the mattress, making the Altar an excellent choice for couples.

Responsive Nano Coil Support

The Altar also incorporates responsive nano coils within its comfort system.

These smaller coils add another layer of responsive support and help the mattress adapt more closely to changes in pressure and sleeping position.

Together with the main pocketed coil system, they create a responsive sleep surface that feels supportive without being rigid.

Firm Tight Top Comfort

The Altar features a Firm Tight Top construction.

Unlike a pillow top or Euro top, the tight-top design provides a flatter, more supportive surface with less initial sinkage.

This feel can be especially appealing to:

• Back sleepers

• Stomach sleepers

• Sleepers who prefer a firmer mattress

• Shoppers looking for stronger spinal support

Self-Response™ Latex

A layer of Self-Response™ Latex provides responsive pressure relief while helping maintain the mattress’s firm feel.

Latex naturally responds quickly to movement, giving the comfort system a more buoyant feel than slow-sinking memory foam alone.

It also contributes to the mattress’s durability and helps provide support around pressure-sensitive areas.

SurfaceTouch™ Gel Memory Foam

The Altar includes SurfaceTouch™ Gel Memory Foam close to the sleep surface.

This layer provides immediate contouring comfort while helping cushion the shoulders, hips, and other pressure points.

The gel infusion also contributes to a cooler, more comfortable sleep surface.

Sleep Climate™ Cooling Technology

Beautyrest’s Sleep Climate™ Technology is designed to help transfer heat away from the body throughout the night.

Combined with breathable materials and performance foams, the cooling system helps reduce heat buildup and maintain a fresher sleep environment.

Advanced Motion Separation

The individually responsive coil systems help limit movement from travelling across the mattress.

This can be especially useful for couples when one person changes positions frequently or gets in and out of bed at different times.

Reinforced Edge Support

The Altar includes reinforced edge support to help stabilize the perimeter of the mattress.

A stronger edge allows you to use more of the available sleeping surface comfortably and provides better support when sitting or sleeping near the side.

Adjustable Base Compatible

The Beautyrest Centennial Altar is compatible with adjustable bases, giving you added flexibility in how you use your mattress.

Pair it with a compatible adjustable foundation to elevate the head or foot of the bed for reading, relaxing, or finding a preferred sleeping position.

Made in Canada

The Altar is Made in Canada, offering Canadian-made construction from one of the most recognized mattress brands.
