OC Mattress Arch Rock Spring Mattress

This mattress is classified as ultra-firm. It is specifically engineered for sleepers who prefer a very rigid surface with minimal sinkage and maximum structural support.

The Arch Rock uses 660 Series Wrapped Coils, which function independently to absorb movement. This design significantly reduces motion transfer compared to traditional interconnected spring systems.

The latex layer provides a responsive, buoyant feel that prevents the 'stuck in the mud' sensation often associated with memory foam. It also adds durability and natural breathability to the mattress surface.

No, the Life Edge® foam perimeter is designed to reinforce the mattress edges. This provides a stable seating surface and ensures you can utilize the full width of the bed without feeling like you might roll off.

Yes, the mattress features targeted center-third support specifically designed to promote proper spinal alignment. This reinforced middle section helps prevent the hips from sinking too deeply, which is often helpful for back sleepers.

All foams used in the Arch Rock are CertiPUR-US® certified. This means they are made without ozone depleters, mercury, lead, or other heavy metals and have low VOC emissions for indoor air quality.
