Sierra Sleep By Ashley Mattress

This mattress is classified as firm. While the gel-infused memory foam layer provides a slight cushioning effect for pressure relief, the underlying wrapped coil system ensures a stable, supportive surface with minimal sinkage.

The mattress is designed with 680 individually wrapped coils, which are excellent at isolating motion. Because each coil reacts independently to weight, movement on one side of the bed is significantly less likely to disturb the other side.

Yes, this hybrid mattress is fully compatible with adjustable bases. Its tight-top construction and flexible coil system allow it to bend and contour to your base's settings without compromising structural integrity.

The gel infusion is designed to help dissipate body heat more effectively than traditional memory foam. While it won't actively refrigerate the bed, it does help prevent the heat buildup often associated with standard foam mattresses.

The steel-encased edge provides a reinforced perimeter around the mattress. This prevents that 'rolling off' feeling when you sit on the side of the bed or sleep near the edge, effectively increasing the usable sleeping surface.

While the mattress is ready to use shortly after unboxing, it typically takes 24 to 48 hours to fully expand to its 12-inch profile and for any initial compression odors to dissipate.
