    Can’t choose between foam or springs? Get the sleep you dream of with the best of both worlds.


Upgrade your sleep sanctuary with the maximum cooling and advanced support of our Astra Extra Firm Hybrid Mattress from the exclusive Celestial Collection. With a cool-to-the-touch tufted fabric surface, the cooling low-density polyethylene fibers rapidly transfer heat to maintain an ideal temperature above conforming foam layers and 2.5 lbs. of copper-infused Visco foam that further cools while relieving pressure points. Specifically designed for targeted support where you need it most, the enhanced 1000 tri-zoned individually-wrapped innerspring system features a thicker and higher coil count nested at the center third, while the foam-encased edge stabilizes and reinforces.
