Luft Mattresses are different than most mattresses. They are made in the USA with all components also made in the USA. These hand crafted Hybrid Mattresses come with multiple safety certifications, meaning the fabric and foams are all free of harmful chemicals and other toxins. Comfort features include Individually Wrapped Coils, laid out in 7 zones so greater support in areas most needed - shoulders and hips, with additional lumbar support. Multiple layers of comfort foam, in the Luxury Firm mattress, include temperature regulating Graphene Infused Premium Memory Foam and multiple layers of Cooling Gel Foam. These mattresses can be shipped direct in a box for easy maneuverability. The Luft Luxury Firm is ideal for a stomach sleeper or a back sleeper who like a layer of softness or a side sleeper who is looking for a little firmness.
