A high-quality mattress is an excellent investment in your enhanced quality of sleep. There are many factors to consider when shopping for the ideal mattress. When browsing, you’ll need to ask fundamental questions about your mattress’s durability. A premium memory foam mattress can grant users 8 to 10 years of high-quality sleep. While thorough research can help you purchase a high-quality memory foam mattress with a guaranteed long lifespan, you’ll need to monitor your investment for signs of wear-and-tear proactively and perform routine maintenance. No matter how well reviewed your memory foam mattress, do your due diligence to ensure a decade of good night’s rest.

How to determine the quality of memory foam mattresses

Before you start shopping for a memory foam mattress, it’s crucial to gather information to make sure you pick one that will satisfy you as the consumer. Mattress quality will affect how you sleep, which will directly correlate with productivity. Superior memory foam mattresses like the Essentia memory foam mattress alleviate pressure on your body’s key points and offer steady support while you sleep.

Because a standard mattress can’t absorb the shock of movement, you may annoy your partner if you cause a disturbance every time you get out of bed to go to the restroom. However, with a high-quality memory foam mattress, you and your partner can sleep soundly. To determine the quality of a memory foam mattress, you’ll need to assess the mattress contents, number of layers, and foam density.

Foam density

Foam density refers to the mattress’s weight per square foot measurement. The denser foams’ cell structures are tightly spaced, affecting the product’s performance and feel. Low-density foams are 2 to 4 pounds, medium density is 4.1 to 5.5 pounds, while high density is more than 5.5 pounds. Although a mattress with a foam density of below 3 pounds may look and feel firm, it can aggravate your body’s pressure points like feet and hips.

Higher-density memory foam mattresses have more cells to support your body weight and conform to your unique shape. With these unique abilities, your memory foam mattress will last longer. However, it’s worth noting that many sleepers may not feel comfortable sleeping on a memory mattress due to its raised density. Typically, a foam density of 4 to 5.3 pounds offers exceptional durability and comfort for most people. A low-density memory foam mattress will last for about 4 to 6 years with proper care and regular use.

Indentation Load Deflection (ILD)

Indentation Load Deflection (ILD) defines a mattress’s hardness or softness, which dictates the overall comfort levels. A high ILD is more firm than one with a lower number. A high-quality memory foam mattress’ ILD ranges from 12 to 14. However, you can comfortably use one higher than 10 ILD. Although compared to density, firmness does not play a huge role in determining a mattress’ longevity, each layer’s ILD and density give you an idea about its feel and wear and tear rate.

Layer Thickness

A mattress’s support core is the firmest, densest, thickest layer because it shapes it and provides a good part of the durability. However, that does not mean a thicker mattress will automatically last longer than a thinner one. A layer’s firmness and density only account for durability and comfort. Two memory foam mattresses with similar layer thicknesses and height may have varying lifespans, depending on each layer’s density.

Factors affecting longevity

Besides the quality of the mattress and time, other factors affect durability.

Frequency of use

Your guest room mattress will last for a more extended period than the one you sleep on every night. The more you sleep on it, the materials begin to compress and fail to bounce back to its original shape. The indentations and sagging happen naturally, and you, unfortunately, can’t stop this process. However, you can do certain things to slow down the deterioration rate, including not placing heavy objects on your bed.

Bodyweight and type

It’s essential to account for your body type and weight when buying a mattress. Although comfort layers promote comfort and softness, your weight will influence their durability. Heavier individuals exert more pressure on the bed, causing premature compression and wear.


Proper maintenance not only extends a mattress’s lifespan but also prevents the growth and spread of dust mites, bacteria, and fungi, which eventually damages its foam. Therefore, avoid drinking and eating in bed, use a mattress cover, and rotate it regularly.

Final thoughts

Memory foam is one of the most durable and well-reputed options on the mattress market. However, getting the most out of your mattress largely depends on your traits as the user. By conducting research and performing routine maintenance, you can find a memory foam mattress that will gift you with quality sleep for many years.
