Memory foam is a type of bed mattress that is made from a variety of materials, including latex, thermoplastic elastomer (TPE), higher densities, and polyurethane.<\/p>\n\n\n\n
Memory foam was invented<\/a> in the 1970s by Dr. James Goodrich and has been used in hospitals and offices ever since because it is durable, comfortable, and supportive. We are now seeing people use memory foam in their homes because of the longevity and durability that it provides.<\/p>\n\n\n\n Some types of memory foam require you to purchase a specific brand, while others do not. While there is some variation between manufacturers, all beds made with this type feature thick layers of organic polyurethane on the topper (2-3 inches) and inside (1 1\/4-1 3\/4 inches).<\/p>\n\n\n\n There are three main types of memory foam: soft, medium-firm, and hard. Each type has its unique characteristics that you should consider when purchasing the best mattress.<\/p>\n\n\n\n Soft Memory Foam Mattress<\/strong> – This type of memory foam is the least supportive and is made from layers of cut-out fill, lower-density foam, and other materials.<\/p>\n\n\n\n It is also the most uncomfortable to sleep on low-density because it allows body heat to escape through the material.<\/p>\n\n\n\n Because the layers of memory foam are so thin and therefore breathable, the bed might move more than a normal mattress would. This can make a side sleeper very uncomfortable for people who have back or hip pain.<\/p>\n\n\n\n Medium-Firm Memory Foam Mattress<\/strong> – Medium-weight materials include polyester fiberfill including medium-density and are denser (thickness) than soft types because it has this type of material on top that adds extra support for heavier individuals.<\/p>\n\n\n\n The same features as the soft memory foam mattress apply to this model as well. When purchasing a medium-firm type, you need to make sure it is paired with another brand of the manufacturer because there are many variations within each category of memory foam.<\/p>\n\n\n\n Hard Memory Foam Mattress<\/strong> \u2013 The hardest version of the sleep surface steps up in high-density foam and would be considered one of the most supportive.<\/p>\n\n\n\n If it wasn\u2019t so hot when sleeping on top since there isn’t a layer of high-density memory foam on top.<\/p>\n\n\n\n This is the most expensive type because it offers up to 40 lbs of support, but it may feel too hard for some individuals who have no back pain or stress issues.<\/p>\n\n\n\n Memory foam<\/strong>, a form of polyurethane foam<\/strong>, possesses viscoelastic traits, enabling it to mold to the body’s contours for pressure alleviation. Density, measured in pounds per cubic foot (PCF)<\/strong>, defines the amount of material within a foam volume. Density influences memory foam’s durability, price, weight, responsiveness, and contouring abilities.<\/p>\n\n\n\n The table below shows the different categories of memory foam density and some of their characteristics.<\/p>\n\n\n\nWhat are the different types of memory foam Density Charts?<\/h2>\n\n\n\n
