Kaymed Beds. A Bed for Life .A Leading Manufacturer of Visco Elastic Memory foam beds and mattresses originally designed for beds on Nasa missions. The main component is a special high density foam which is incredibly elastic: When it comes into contact with body heat it takes on the exact shape of the body, without applying pressure on any part; when contact ceases, the mattress returns to its original form.The body immediately finds the best sleeping position, reducing the tossing and turning movements which disturb sleep by 80%. The extraordinary features of the memory foam mattress prevent the numbing of muscles and nerves and allow the blood to circulate freely; increasing the breathable qualities of the mattress, leaving the skin cool and dry.
