Sweetnight CoolNest Mattress

Yes, it uses a combination of a cool-to-the-touch cover and PCMFLUX foam technology. The cover wicks away moisture, while the foam actively absorbs and dissipates body heat to prevent the overheating often associated with traditional memory foam.

A medium firmness is generally ideal for side sleepers. It provides enough give to cushion your shoulders and hips while maintaining enough support to keep your spine aligned.

The 5-zone design provides targeted support to different parts of your body, with firmer areas under your hips and lower back and softer areas under your shoulders. This helps maintain neutral spine alignment and reduces pressure points that can cause morning aches.

Because this is a 14-inch memory foam mattress, it performs best on a solid, flat surface like a platform bed, an adjustable base, or a slatted frame with slats spaced no more than 3 inches apart. A box spring is not required, but if you use one, ensure it is in good condition and provides a flat, supportive surface.

Yes, the foam used in this mattress is CertiPUR-US certified. This means it has been tested to be free from ozone depleters, mercury, lead, and other heavy metals, and has low VOC emissions for indoor air quality.

While the mattress will be ready to sleep on within a few hours, it typically takes 48 to 72 hours to fully expand and reach its optimal firmness and shape. We recommend waiting at least 24 hours before using it to ensure the best experience.
