King Koil Ortho Firm Super Mattress

Established in 1898, King Koil is a legacy brand globally recognized for its commitment to quality and orthopedic support. The Ortho Firm Super is designed for sleepers seeking a highly supportive, firm sleep surface without compromising on modern mattress technology. Ideal for back sleepers or those needing robust lower back support, this model combines a sophisticated 5-zone pocketed spring system with enhanced edge stability. Visually, it features a classic, tailored look that fits seamlessly into any bedroom.

Key Highlights

• Firm Orthopedic Support (Firmness 7-8): Falling on the firmer side of the scale (7-8 out of 10), this mattress is engineered for robust support. It is often favored by back sleepers who experience lower back strain and require a surface that resists sagging and maintains proper postural alignment.

• Specialized 5-Zone Individual Pocketed Spring System: Instead of traditional linked springs, the Ortho Firm Super utilizes an advanced 5-zone individual pocketed spring system. Heavier gauge coils and increased coil concentration are strategically placed to create contour zones that respond specifically to different areas of the body. Because the coils are individually encased, they move independently, meaning motion transfer is minimized—ensuring an undisturbed night's rest for you and your partner.

• Chiropractor Tested & Endorsed: A major selling point of King Koil is its exclusive endorsement by the International Chiropractors Association (ICA), a partnership held since 1967. This means the mattress has been designed and tested to help promote proper spinal alignment and a healthier night's sleep.

• Excellent Edge™ Foam Encasement: The mattress perimeter is reinforced with a high-resilience foam encasement. This critical feature provides greater overall stability, creates a firm seating edge, and prevents the sensation of rolling off, thereby maximizing the usable sleeping surface.

• Advanced Turn-Free Technology: Designed for modern convenience, the Ortho Firm Super utilizes advanced technology and durable components that eliminate the need to periodically flip the heavy mattress, making maintenance effortless.

• Hygienic Sleep Environment: The sleeping surface is treated with Ultra Fresh® technology, which has natural anti-bacterial and anti-fungal properties, reflecting a commitment to a clean and healthy sleep environment.
