Advanced Technology

The Terra Sleep 12-inch Firm Mattress by Ashley delivers eco-forward luxury without skimping on support.

Crafted by Ashley Furniture Industries, the mattress starts with a breathable stretch-knit cover made from REPREVE® recycled bottles for a cooler, planet-kind surface.

Next, a layer of FSC-certified Talalay latex teams up with individually wrapped coils and high-density support foam layers to create orthopedic spinal alignment support that back- and stomach-sleepers adore.

Because of this hybrid core (and the perimeter edge reinforcement), sleepers experience steady lift, reduced roll-off, and motion isolation (a hybrid technology that keeps partners undisturbed).

Moreover, the feel registers firm yet gently pressure-relieving, making it a top contender for anyone hunting the best 12-inch firm mattress for back pain or a firm mattress for stomach sleepers in the USA.

And, every unit is adjustable base compatible and protected by an Ashley 10-year limited warranty, delivered via free shipping in the USA, and qualifies for financing available at checkout.

Key Mattress Benefits

5 Layers
Of Cooling
Comfort

Made from recycled REPREVE® fibers, the eco-smart cover wicks heat away, ensuring a cooler sleep surface. It also helps shrink your carbon footprint while providing a breathable, soft fabric feel.

The Talalay latex layer naturally vents excess heat, ensuring a balanced sleep temperature throughout the night. It provides a buoyant, responsive feel that enhances comfort while promoting proper spinal alignment.

The pocketed coils adapt to each sleeper’s body, offering personalized support. The perimeter edge reinforcement maximizes usable sleep space and prevents sagging, providing additional stability.

The high-density foam base adds solid support and durability to the mattress. It ensures long-lasting performance by stabilizing the entire mattress structure, preventing sagging over time.
