Foam BedsOne recent addition to the myriad of sleeping surface materials on the market today is memory foam. Also called visco-elastic foam, this material is actually made of polyurethane, with some additional chemicals added in order to increase the viscosity level. This property is what gives the substance the unique feel of molding to a person’s body when laying on it. Originally developed by America’s space program, memory foam was ultimately deemed unfit as a material for use in closed environments such as space capsules, so it was never used in any missions. It began to be used in the medical industry, however, as some saw its potential as a relief from pressure sores, as it has the uncanny ability to spread the weight of one’s body over a wide area, thus reducing pressure points. Several shortcomings of that first generation of memory foam were soon discovered, as it would eventually compact and develop cracks over a period of time. The Swedish company Tempur-Pedic ® developed their own version which overcame these shortcomings and was found to be more durable than its predecessors. It initially sold only to the medical industry, but as patients raved about the benefits of the material, the company soon came out with a line of memory foam products for the beds of consumers. These days, there are many different manufacturers of memory foam beds, mattress pads, and pillows, and the competition has benefited the consumer in the form of reduced prices and higher quality. While sleeping surfaces made from this material can be extremely comfortable, evidence also exists that memory foam can also help people with sleep disorders. Obstructive sleep apnea (OSA) is a disorder in which the body stops breathing while asleep due to an obstruction such as fat deposits or body positioning, and some sufferers of this malady claim that memory foam beds give them relief from their symptoms. It allegedly helps by allowing people to more comfortably sleep on their side, which is the ideal position to prevent this condition from occurring. This position also allows sufferers of OSA to use special pillows that were developed to help prevent the problem, as they only help when one is sleeping on his side. In addition, the extra support provided by memory foam beds help keep the spine and airway aligned, which is said to further decrease the symptoms of OSA. Other benefits of memory foam beds are the lack of any area for bedbugs to hide, as there are no open spaces in the mattresses, and a general durability of the material. Mattresses made from memory foam are supposed to last longer than standard coil mattresses, which can be a way for one to justify the extra cost of this type of bed. Although memory foam never made it into space, it has succeeded in making it into the mainstream of sleeping surface materials, as sales of memory foam beds, mattress pads, and pillows continue to increase. The numerous benefits of this space-age material easily justify the added expense to purchase it.
