Luxury Firm Support with a Premium Feel

The 12 Inch Luxury Firm Mattress from the Infinity Collection by Maxim Mattress combines a firm comfort direction with SmartFoam HD comfort layers, Maxim’s OrthoCoils+ pocket-coil system, reinforced perimeter support, and CertiPUR-US® certified foams. Its 12-inch profile creates a substantial mattress height while retaining the more structured feel associated with a firm model.

The Infinity Firm is intended for shoppers who want less surface sink than a plush mattress but still prefer cushioning above the underlying coil system. Its combination of foam and individually wrapped coils creates a responsive construction rather than an all-foam feel.

12 Inch Luxury Firm Mattress with OrthoCoils+ Support

The 12 Inch Luxury Firm Mattress combines several confirmed Maxim technologies.

Key Features

• 12-inch mattress profile
• Firm comfort level
• SmartFoam HD comfort layers
• OrthoCoils+ pocket-coil support
• Individually wrapped coils
• Reinforced perimeter support
• CertiPUR-US® certified foams
• Maxim Mattress construction

Exact foam thicknesses, densities, coil count, and coil gauge were not supplied.

SmartFoam HD Comfort Layers

SmartFoam HD forms part of the upper comfort system of the Infinity.

SmartFoam HD Functions

• Adds cushioning above the coil system
• Responds to body pressure
• Supports the mattress’s firm comfort direction
• Creates a more refined surface than a bare coil system
• Works with the OrthoCoils+ support below

The 12 Inch Luxury Firm Mattress should not be assigned specific SmartFoam HD density or thickness values unless Maxim provides those specifications.

OrthoCoils+ Pocket-Coil System

The Infinity uses Maxim’s OrthoCoils+ support system with individually wrapped coils.

Pocket-Coil Characteristics

• Individual coil response
• Responsive underlying support
• Works beneath the foam comfort layers
• Helps keep some movement more localized
• Creates a hybrid-style foam-and-coil feel

No exact coil count, gauge, zoning configuration, or verified lumbar-support specification was supplied.

Firm Comfort Profile

The Infinity is specifically positioned as a firm mattress.

May Suit

• Back sleepers who prefer stronger support
• Stomach sleepers who favor less surface sink
• Combination sleepers who prefer structure
• Couples with similar firmness preferences
• Shoppers moving away from plush mattress designs

Comfort is subjective and depends on body weight, sleep position, foundation, and personal preference.

Firm Surface with Added Comfort Layers

The Infinity combines firm overall positioning with cushioning from the SmartFoam HD system.

At the Surface

• Foam cushioning
• More refined first contact
• Controlled contouring

Underneath

• Individually wrapped OrthoCoils+
• Responsive support
• Firmer overall structure
• Reinforced perimeter

This allows the 12 Inch Luxury Firm Mattress to deliver a structured feel without positioning it as an entirely rigid sleeping surface.

Reinforced Edge Support

The Infinity includes reinforced perimeter support.

Edge Support Functions

• Adds structure around the mattress perimeter
• Supports the outer sleeping area
• Provides additional stability when sitting near the edge
• Helps make more of the mattress surface usable

The exact reinforcement material and edge-support construction were not supplied.

Shared Bedroom Considerations

Individually wrapped coils can respond more independently than interconnected springs.

That may help keep some movement more localized across the mattress surface, making the Infinity relevant for shared-bed use.

No specific motion-isolation test results were supplied, so the mattress should not be described as eliminating partner disturbance.

CertiPUR-US® Certified Foams

The supplied information states that the foams used in the Infinity are CertiPUR-US® certified.

This certification applies to qualifying polyurethane foam and addresses criteria related to content, emissions, and durability testing.

The certification should not be interpreted as applying automatically to every non-foam component of the mattress.

12-Inch Mattress Profile

The Infinity has a confirmed 12-inch overall height for the listed configuration.

Profile Considerations

• Creates a substantial finished mattress height
• Works naturally in many primary-bedroom setups
• Should be considered with bed-frame and foundation height
• Can fit standard bedroom styling without an excessively tall profile

Before ordering, confirm the exact size-specific dimensions and finished height with the intended bed setup.

Foundation and Bed Frame Compatibility

The supplied information identifies compatibility with standard frames, platform beds, and compatible adjustable bases.

Before Setup, Confirm

• Mattress size
• Bed-frame dimensions
• Platform requirements
• Slat spacing
• Center-support requirements
• Adjustable-base compatibility
• Foundation requirements

The 12 Inch Luxury Firm Mattress should always be supported according to Maxim Mattress recommendations.

Care & Maintenance

Routine care can help preserve the mattress surface and internal support system.

Mattress Care

• Use a manufacturer-approved supportive base
• Add a mattress protector if desired
• Keep the surface clean and dry
• Address spills promptly
• Avoid excessive moisture
• Follow Maxim Mattress cleaning instructions
• Avoid folding or bending unless approved

Rotation

Rotate the mattress head-to-foot only if Maxim Mattress or the applicable warranty recommends it.

Do not assume that the Infinity is designed to be flipped unless two-sided construction is confirmed.
