PERMA-FIRM EDGE SUPPORT

No Sagging. No Slide-Off. No Compromise.

Perma-Firm Perimeter Edge Support

Most mattresses feel great in the center.
The real test is what happens at the edges.

That’s where Perma-Firm Perimeter Edge Support makes the difference.

What Is Perma-Firm Perimeter Edge Support?

Perma-Firm is our proprietary edge support system originally engineered for hotel use, where mattresses are sat on, slept on edge-to-edge, and expected to hold their shape night after night.

Instead of relying on a narrow strip of soft foam around the perimeter, Perma-Firm uses a significantly wider, higher-density foam encasement that surrounds the entire mattress support system.

The result is a mattress that stays stable, supportive, and usable across the full surface.

Why Edges Matter More Than You Think

Weak edges are one of the first areas where a mattress breaks down.

They cause:
• Sagging when you sit on the side
• A “rolling off” feeling near the edge
• Reduced usable sleeping space
• Faster overall wear and loss of support

Perma-Firm was designed to solve all of that.

A Wider Sleeping Surface You Can Feel

Typical mattresses only reinforce about 2 inches along each edge. Our Perma-Firm system increases that edge support by roughly 2.5 times.

What that means for you:
• You can sleep closer to the edge without feeling unstable
• Couples gain more usable space across the mattress
• The mattress feels consistent from center to edge

You are not confined to the middle of the bed.

Stronger Support Where You Sit Every Day

Getting in and out of bed puts the most stress on the perimeter.

Perma-Firm uses firmer, high-density foam specifically chosen to resist compression and breakdown in these high-use areas. The edge stays upright and supportive instead of softening and collapsing over time.

That stability is especially noticeable when:
• Sitting on the side of the bed
• Tying shoes or standing up
• Sleeping near the edge

Built to Last Longer

Perma-Firm was developed to extend mattress life in commercial environments. That same construction benefits your home in a simple way.

The mattress keeps its shape longer.
The support holds up longer.
The edges don’t give out early.

Less breakdown means the mattress feels consistent year after year instead of changing after the first few.

Why Hotels Demand This Kind of Support

Hotels cannot afford mattresses that lose edge support quickly.
Guests sit on them constantly.
Mattresses are used every night.

Perma-Firm was built to handle that level of use, then brought directly to the consumer without being softened, simplified, or redesigned.

You are sleeping on the same edge support system used in our hospitality mattresses.
