Sierra Sleep Mattress

This mattress is designed for sleepers who prefer a supportive, stable surface with minimal sink-in. It uses a combination of dense foam layers and wrapped coils to keep your spine aligned, making it a strong choice for back or stomach sleepers who need extra support.

No, it is designed to help regulate temperature. The comfort layers include gel-infused memory foam, which is specifically engineered to dissipate body heat and keep the surface cooler than traditional memory foam.

This model features a steel-encased perimeter, which reinforces the edges of the mattress. This prevents that 'rolling off' feeling and allows you to use the full surface area of the bed without the sides sagging.

Yes, it is a hybrid. It combines the pressure-relieving benefits of memory foam and cotton comfort layers with the responsive, consistent support of 680 wrapped steel coils.

Once you unbox the mattress, it will begin expanding immediately. While you can sleep on it the same day, it typically takes 24 to 48 hours to fully expand to its 12-inch profile and for any initial packaging odors to dissipate.

Because this is a 12-inch hybrid mattress, it works well with most solid platform beds, adjustable bases, or traditional box springs. Just ensure your foundation is sturdy and provides even support across the entire surface.
