The memory foam futon has become popular due to the firm support it provides while offering the flexibility of a standard futon. Choosing the best model to match your needs will depend on several factors, including the futon's size, the density and thickness of the foam desired, as well as your space, budget, and existing decor. Low- and high-density memory foams have somewhat different characteristics. Check the manufacturers' warranties and find out if the dealer will accept returns or exchanges.
If you plan to use a frame you already own, that will govern what size memory foam futon should be purchased. Be sure the models you consider will both fit in your frame and in the planned space. There are specialty futons available, such as convertible futon sofas, futon chairs, and futon bunk beds, that are made with memory foam. Futon mattresses and memory foam generally are quite heavy, so be sure that you are able to open and close any convertible futon you consider.
Memory foam is recommended for people who prefer a high level of support, those who often suffer from backaches, or invalids who must spend a significant amount of time in bed. The foam is manufactured in a range of densities and thicknesses. Generally, people with more athletic builds and angular anatomies prefer higher density foam. Those with more rounded figures tend to prefer a less dense memory foam futon. Higher-density foam softens in contact with body heat and takes a few minutes to conform to the body. Lower-density memory foam is pressure-sensitive and molds to body contours quickly, but tends to have a somewhat shorter life.
In comparing various models, determine how thick the memory foam padding is. Look for a thickness of at least 2 inches (58 mm); less than that will not offer noticeable support. When shopping for a memory foam futon, compare the warranties offered. A longer warranty can be a sign that better-quality materials have been used.
Most memory foam releases a distinct odor which some people find objectionable, but these odors usually lessen over time and with airing. Statistically, mattresses and futons that include memory foam tend to cause more respiratory distress among sensitive sleepers than do standard mattresses and futons. Some types of foam with tight cellular structures also tend to retain body odors. Ask the dealer what return or exchange privileges might apply to your newly purchased memory foam futon.
