There are two major complaints about memory foam mattresses. The first complaint has to do with the odor that the mattresses emit. The second complaint has to do with how warm the mattresses get at night when you're sleeping on them.
As for the odor, this is a known issue with memory foam mattresses. The manufacturing process and the chemicals used to make the mattresses results in a strong chemical smell. New mattresses should, when placed in the bedroom, be left uncovered (blankets off) during the day, with the windows open if at all possible. The smell can last anywhere from two weeks to eight weeks. If the bedroom is well-ventilated then the odor will not last as long. In general, while some people worry about health risks, the odor is not necessarily bad for you. It is just very unpleasant.
As for the temperature, this is also an issue reported by many users of memory foam mattresses. This is due to several reasons. First, the foam does conform to your body, which means more heat is trapped against the mattress than a normal mattress. Also, the foam which makes up the mattress does not allow heat to escape. It holds the heat right next to your body, resulting in a steep rise in temperature. If you have a body type that emits heat readily while you sleep, a memory foam mattress can become very uncomfortable for you rather quickly and even with some of the mattress toppers that are sold by memory foam manufacturers, the heat can still be unbearable for someone who gets warm at night normally. If you're not typically hot at night, or if you frequently get cold at night, the memory foam mattress can feel rather nice.
When all is said and done, if you can work around these two issues, a memory foam mattress does offer very good support, and a very comfortable night's sleep. As long as you are aware of the potential issues, you may still decide to buy a memory foam mattress and be very happy with your purchase.
