The Air-Visco Mattress has two air chambers and that can be independently adjusted from "pillow-soft" to "extra firm", to suit the individual preference of each sleeper.

The dual "push button" firmness control can instantly change the firmness of each side and of the mattress to suit the specific size, weight, and shape of each sleeping partner. When you change the mattress firmness for various reasons, the control has a unique memory function that automatically instantly returns the firmness to your "preset" most comfortable firmness setting.

The amount of air in each air chamber determines the firmness for each sleeper. The desired comfort and proper spinal support are achieved simply and instantly with the press of the control button NOTE: Twin and full size beds have only one air chamber. The shape of the arrows illustrates how smoothly the air conforms to the body's shape, providing smooth, uniform support to the entire body, regardless of sleeping position, size, weight, or shape.

The edge of the mattress is firmer for comfortable sitting, due to the high-density foam rails that completely surround, and fully protect the air chambers from ever being damaged.

A 3" thick layer of specially formulated, NASA developed "Visco-Elastic" foam, completely covers the top of the air chambers and side rails. No other foam has the unique properties of "Visco Elastic" foam, which is heat sensitive. As it warms from your body's temperature, it molds to your exact shape to uniformly and completely support your entire body, alleviating all pressure points that cause discomfort.

The plush mattress top cover contains 100% pure wool, which is antimicrobial and dust mite resistant. Because wool's fibers are soft and springy, they naturally conform to your body's shape. And, because wool can absorb up to 1/3 of its own weight in moisture, it continually draws moisture away from your body all night long, keeping you (and your sheets) drier. Studies show that on average, a person perspires up to one cup of fluid each night, so, this is a very desirable and unique feature. Keep in mind also, that wool keeps you cooler when it's hot, yet warmer when it's cold! Wool is also fire retardant. The plush mattress top cover is made of a beautiful pattern of cotton/polyester blend percale, which is extra comfortable because air can pass freely through it. The fabric is beautifully quilted, smooth to the touch, durable, and above all, the top is removable and machine-washable, which is a tremendous advantage over other mattress tops, which are not machine washable, and, therefore, are infested with germs, molds, mildew, dry skin flakes, perspiration, dirt, dust mites, stains, and odors from years of use.

A continuous Velcro™ strip completely encircles the mattress, permitting simple removal and replacement after routine machine washing. The Velcro™ is easy to use, and far more durable than a zipper. It positively will never wear out, or break like a zipper from use.

The mattress bottom is made from an anti-skid material, which is specifically designed to keep the mattress from sliding on the box spring or platform when making up the bed.
