What to Look for When Buying Memory Foam Mattresses

Memory foam mattresses are becoming increasingly popular among consumers due to their superior comfort and support. However, with so many options on the market, it can be difficult to know what to look for when buying a memory foam mattress. In this article, we’ll explore the key features to consider when shopping for a memory foam mattress.


The density of a memory foam mattress refers to the weight of one cubic foot of the foam. A higher density typically means better support and durability. While lower density memory foam mattresses may feel softer initially, they tend to wear out faster and lose their shape more quickly. It’s recommended to look for a density of at least 4 pounds per cubic foot, with 5-6 pounds being ideal for maximum support and longevity.


Memory foam mattresses come in a range of firmness levels, from soft to firm. It’s important to consider your personal preferences and any medical conditions that may require a certain level of support. For example, if you have back pain, you may want a firmer mattress to provide proper support. However, if you’re a side sleeper, a softer mattress may be more comfortable. It’s also important to note that memory foam mattresses tend to feel firmer in cooler temperatures and softer in warmer temperatures.


The thickness of a memory foam mattress can vary from 6 to 14 inches, with thicker mattresses generally providing better support and comfort. However, a thicker mattress may not be necessary for everyone. If you’re a lighter person or prefer a softer mattress, a thinner option may be suitable. Additionally, a thicker mattress may require deeper-pocketed sheets and a higher bed frame to accommodate the added height.

Heat Retention

One common complaint about memory foam mattresses is that they can retain heat, causing discomfort for some sleepers. Look for mattresses with cooling features like gel-infused foam or a breathable cover to prevent heat buildup. Additionally, consider the climate you live in – if you live in a warm area, a cooler mattress may be more comfortable.


When shopping for a memory foam mattress, look for certifications that indicate the product meets certain standards for safety and quality. Certifications like CertiPUR-US indicate that the foam has been tested for harmful chemicals, emissions, and durability. Other certifications like Oeko-Tex Standard 100 ensure that the mattress meets high environmental and safety standards.

Trial Period and Warranty

Finally, it’s important to look for a memory foam mattress that comes with a trial period and warranty. Many mattress companies offer a 30- or 90-day trial period, during which you can return the mattress if it doesn’t meet your expectations. A warranty of at least 10 years is also recommended to protect your investment and ensure you get the most out of your new mattress.
