Before choosing a memory foam mattress, consider the construction of the mattress and the properties of the material. A good memory foam mattress yields the best benefits if you consider some important factors before buying one.
Instructions
Considerations
1. Look at the mattress' indentation load deflection grading, also known as ILD. This grade is provided by beds.org to advise health practitioners. The ILD grade refers to the weight required to compress memory foam to 25 percent of its thickness. Beds.org notes that most people prefer a mattress with an ILD of between 10 and 16.
2. Just as important as the mattress' ILD is its density. A mattress with a higher density--usually 4 pounds or more--will give you more "memory." Higher-density memory foam mattresses are also more durable and last longer.
3. See how the mattress is constructed. Beds.org states that many memory foam mattresses may be layered with other materials--such as latex foam--to give for support and comfort. But make sure there's enough memory foam in the mattress to make a difference; too little or too much memory foam will be uncomfortable.
4. Test the mattress yourself, if you can. Memory foam has the unique capability to mold to the body once weight is applied and returns slowly to its original shape after weight shifts or is removed. If you prefer a springier mattress that's more similar to a traditional box spring set, you might not want a memory foam mattress.
