Memory foam refers to polyurethane materials, whose density and viscosity are improved by the addition of other chemicals. A common feature of memory foam is its tendency to soften when in contact with heat produced by the body. The body heat literally transforms the foam so that it can take the form of the human body. Memory foam is also quick to recover; It is converted within a few seconds to its original form once not in contact with the human body.
Memory foam mattresses have high density compared to mattresses made of other materials. They prove to be very supportive. Choosing the best memory foam mattress can be a challenge and below are just some of the things you need to look at when shopping for one.
Although this type of mattress generally has a high density, it is important to consider the density of one you intend to buy. You have to note that density does not determine how a foam mattress feels like a memory. It only serves to indicate how durable the mattress is. Durable memory foam mattresses have a density between 5-7lb.
This is one of the most important things you need to look at when shopping for a foam mattress. Touch here refers to how a memory foam cartridge reacts when lying on it. It is important that you choose a foam mattress of 32mmHg or less. Such is a mattress that provides effective blood circulation when you sleep. It is also important to note that a memory foam mattress pressure level is determined by the number of layers in the mattress, which is called Foam ILD (Indentation Load Deflection). This determines the comfort level of the mattress. It is recommended to settle on a mattress with between 10-16 ILD.
Type of foam
It is important to consider what kind of memory foam is used to make a mattress before sharing with your money. There are both natural and ordinary memory foam mattresses. Regular memory foam mattresses are generally called viscoelastic or viscose. These are traditionally manufactured using petroleum-based chemicals. You can choose a mattress made of natural foam as your best memory foam mattress if you are health conscious.
