Amico’s Non-Powered Therapeutic Mattresses play an important role in your decision for ulcer prevention. With our surface modification technology, our line of foam mattresses provide unsurpassed pressure redistribution. Pressure ulcers result from prolonged pressure that cuts off the blood supply to the skin, causing the skin and other tissue to die. The damage may occur in as little as 12 hours and may go unnoticed until the skin begins to break down, days later.
