In order for a memory foam mattress to be supportive and comfortable for an overweight or obese person, it must be firmer and made of higher density viscoelastic, so that it can relieve pressure and provide a restful night’s sleep. Most high-quality foam mattresses are already quite dense. This makes them suitable for a larger person. But, because the additional weight creates greater pressure, the cell structure that comprises the memory foam may wear down slightly faster than normal. It will not, however, significantly shorten the life-span or durability of the mattress or mattress topper.
Viscoelastic foam softens over time. This is to be expected. Many people notice that within a few weeks or months of purchase their foam mattress or topper becomes softer, and mistakenly think that it’s wearing out quickly. Softening is a normal condition in foam mattresses as a result of the break-in process. However, overweight people may notice a quicker softening in their mattresses.
A good quality mattress such as an AstraBeds Memory Foam sleep system does soften, but support is being properly maintained because of the high density of the foam and the heat-changing firmness rating as well as the firm mattress core. In other words, a memory foam mattress or topper may become softer, but this softening does not amount to faster or abnormal breaking down if it still provides adequate support.
Almost regardless of a person’s weight, a high-quality visco foam mattress will provide support and comfort without sagging for up to 15 years. A high-quality foam mattress topper will last up to 4 years… provided it’s used over a solid foundation, and is of the appropriate thickness.
A durable, built-in mattress foundation teamed with a reasonably thick memory foam layer on top will help a memory foam sleep system maintain its performance over a long period of time. This makes either a memory foam mattress or mattress topper a good choice for overweight people.
