Sierra Sleep By Ashley Hybrid Mattress

Yes, this is designed as a firm mattress. It balances the structural support of 918 wrapped coils with high-density foams, making it a solid choice for sleepers who prefer a surface with minimal sinkage and strong pushback.

Absolutely. The hybrid construction, which combines flexible coils with responsive memory foam, is specifically engineered to be compatible with adjustable bases, allowing you to elevate your head or feet without damaging the mattress core.

Yes, it features an Ashley Edge steel-encased support system. This perimeter reinforcement prevents the sagging often found in foam-only mattresses, providing a stable surface that allows you to use the full width of the bed.

While you can typically set it up immediately, the mattress requires 48 hours to fully expand and reach its optimal firmness and comfort levels. We recommend giving it that time to ensure the foam layers and coils settle properly.

The mattress utilizes a multi-layer construction featuring Laytech foam, high-density response memory foam, and high-density whisper foam. This combination is designed to contour to your body while maintaining the firm, supportive feel characteristic of this model.

The 14-inch profile, combined with 918 power-packed 15-gauge coils and steel-encased edge support, provides a robust foundation. This construction is generally well-suited for sleepers who need extra durability and consistent support throughout the night.
