Thoughtfully crafted with unparalleled attention to detail, the Nautica Home Calm mattress provides the cooling and supremely soothing comfort that only Nautica home can offer. An advanced cooling liquid gel-infused comfort foam, combined with a patented edge support structure and ultra-responsive support foam layer, the nautica home memory foam mattress a comfortable night sleep time and time again. Cooling liquid gel infused microtec gel memory foam maintains continuous and pressure-free, body cradling support allowing you to take way up feeling refreshed and rejuvenated night after night. Channel vented for maximum thermal control and cooling, an advanced layer of high-performance latex engineered foam offers the responsiveness of latex with the calming and contouring, yet elegant feel of cooling liquid gel. An ultra-firm, patented foam tray design surrounds the entire circumference of the mattress, increasing the overall sleep surface and preventing edge sag. The foam perimeter sits directly under the upper comfort layers to add additional edge support while still remaining remarkably comfortable. All nautica memory foam mattresses rest atop a tri-zone, channel vented foam spring support base that increases contouring to your body and provides the healthy lumbar support your body needs to reduce lower back pain. Strategically positioned to offer the maximum support and allow for additional cooling comfort, the channel vented design increases horizontal airflow to keep you and your mattress feeling fresh. Simple and easy to remove, the 360 zipper allows the stretch knit cover to be machine washed for a fresh, clean and comfortable sleep environment.
