Durability: On average, a mattress should at least work for a minimum of 7 years. But that still is a lot for some mattresses which after 4 to 5 years starts to show indentations and sagging on the sleeping surface. A complete history of the mattress company is really important when considering durability but that sometimes becomes hard as some of the top brands have only been in the market for just a couple of years.
Firmness: this means how soft or firm the mattress is which is referring to the topmost layer of the mattress which is right under you. By far, there is no perfect firmness level mentioned by any research, which indicates that it is truly based on an individual’s needs. Nonetheless, people prefer a medium-firm mattress to keep things in balance.
Support: this is directly related to the support core of the mattress which is located right under the comfort layer. A mattress which tends to keep your spine straight has the best support, while which sags in the middle can cause many problems like back and shoulder pains.
Pressure relief: some mattresses are designed to contour around sleeper’s body. This can help alleviate pressure points all along the spine which is very healthy for people especially with back pains and side sleepers. If you want to get rid of pressure, a close-conforming mattress will be an ideal choice which perfectly provided by memory foam and latex.
Edge support: some manufacturers add a layer of high-density polyfoam around the support core. This helps to get rid of sinkage at the edge where usually people sit and helps maintain good edge support. Latex mattresses are usually not a good choice when considering edge support.
Motion isolation: to cut down those night time disruptions you need to consider motion isolation when buying a mattress. Latex and foam have proved to absorb movement and keep it confined to the area of sleep.
Temperature neutrality: if you tend to sleep warm or cool, then this factor must be considered. Some mattresses like memory foam are a major heat trap as they absorb a tremendous amount of body heat which can make your sleep time very uncomfortable. Innersprings have proved to dissipate heat which is perfect for cool sleepers.
Noise: mattresses with metals parts and electric component tends to be noisy like hybrids. On the other hand memoryfoam and latex produce the least noise when bearing weight.
