Combining copper infused memory foam and a soft cover with a wrapped coil design, Aireloom's Hybrid 12.5"" Firm Mattress delivers a supportive base, along with a cool-to-touch feel. Aireloom was founded in 1940 by King Karpen, the originator of California comfort. Aireloom mattresses are handmade and constructed using the timeless craftsmanship and innovative methods they've perfected over 75 years. The process is a labor of love, performed by true craftsmen who focus on every cut, every stitch, every piece of material that goes into making sure you experience the most comfortable night's sleep possible.
