You probably heard about the comfort, support and other benefits of a memory foam mattress. That’s what prompted you to make the decision to discard your old inner coil and buy a memory foam mattress. With the wide range of choices available, it’s helpful to know what to look for in a memory foam mattress to ensure you buy the right one.

How to Buy Right Memory Foam Mattress

Here are important tips to ensure you buy the right memory foam mattress for yourself.

1. Look for adequate pressure relief

Adults with average body weight should ideally look for a memory foam mattress that provides for pressure relief. When you sleep, your body gravitates into the mattress. This could cause a lot of discomforts as skin and circulation are constricted causing stiff and painful joints.

Your memory foam mattress should effectively distribute weight throughout the mattress to offer quality rest. The mattress should have an mmHg level (millimeters mercury) the same or lower than what the human body maintains at 32mmhg.

Anything above 32 mmhg will cause discomfort and disturbed sleep. Lower values of 15mmg value are great for side sleepers and people on the heavier side.

2. Look for right firmness levels

Knowing what firmness levels you need make it easier to buy a memory foam mattress. Users have firmness levels based on age, gender, weight, sleep styles and other preferences.

Your memory foam mattress should provide you with the right amount of cradling if you are lightweight and a push back in case of heavier people. Mattress firmness levels range from soft, plush or ultra plush to firm levels that don’t cause any sinking effect.

It is also helpful to know the ILD levels (Indentation Load Deflection) or the IFD levels (Indentation Force Deflection). These measures tell you how soft a firm a mattress is when compressed by 25%.

For example, a 20lb ILD or IFD rating would mean that the foam needed 20lbs of pressure to indent it by 25%. Remember that higher the ILD, the firmer the foam. Knowing the ILD is important in telling high-quality foams with high ILD ratings from lower quality – lower ILD ratings.

3. Look for right kind of comfort

When looking for a memory foam mattress, factors such as firmness and pressure relief and support have no importance if personal comfort is not a criterion. Don’t invest in a memory foam mattress that has sufficient firmness or adequate support if it’s not comfortable for you. Comfort is a matter of perspective and so a first-hand test and feel of the mattress in a store is how you can personally assess its comfort level.

Your memory foam mattress should give you the feeling of comfort in the top layers of the mattress. It should also provide a decent level of embrace and bounce to support sleeping on your back, side or stomach and in any position.

At the same time, the mattress should have a quick response and offer comfort levels that allow for a change in positions freely during the night, all while relieving pressure points.

4. Look for adequate support based on your requirements

Your memory foam mattress should be effective in supporting your body and providing for alignment. Higher the resilience and quality of the mattress, better the support. Better memory foam mattresses add a top layer of memory foam that conforms to the body.

The lower levels of memory foam are usually high resilience and high density to provide adequate support. Mattresses with resilient support layers will also provide for motion isolation. This is ideal for couples to sleep peacefully through the night.

It is thus advisable to choose a mattress with a combination of memory foams that provide for both comfort and support.

While most memory foam mattresses have lesser edge support in general, it could help to find a mattress with a decent amount of support at the edges.

5. Look for right density of mattress

Density doesn’t measure the firmness of memory foam. Foam density is directly related to the foams durability. A 6pound memory foam mattress will offer more cushioning, be more resistant to softening and last longer than a 4 pound memory foam over a span of 8 to 10 years.

Memory foam mattresses usually combine layers of foam of various densities. Make sure that all these layers from the top to the support layer contain the density of adequate levels that can contribute to durability.

6. Look for right thickness based on your requirements and usage

Memory foam mattresses range in thickness from as thin as under 6 inches to 14 inches thick. When choosing a mattress, remember that thicker mattresses are more comfortable for adults than thinner mattresses that can be used for kids.

Most memory foam mattresses have more than 2 layers that add up to thickness value. The base layer is usually offered firmer support while the layers closer to the surface are generally softer. Memory foam mattresses for kids beds should not be too thick especially in the case of top bunks.

7. Go for a combination of materials

For an ideal sleep environment, look for a hybrid mattress that combines memory foam along with other fabrics. For example, mattresses with latex in the top layer and memory foam in subsequent layers. Mattresses can also have organic natural materials near the surface with memory foam support layers. There are gel infused memory foam mattress too.

Ideally, mattresses should have a blend of memory foam of more than 3 to 4 pounds in density in the base layer and natural latex in the first layer. These kinds of mattresses get positive reviews as providers of adequate support, soft comfort and pressure relief.

8. Try yourself or Go through review before buying

It is best if you can try the memory foam mattress yourself in the store before buying. If that is not possible go to the ones which provide a trial period.

Another way to choose right mattress, especially when buying online is to look for verified customer reviews. Some aspects of a memory foam mattress that are not specified on labels are mostly identified through online reviews. These factors are whether the amount of heat retention, breathability and airflow.

The mattress’s ability to isolate motion is an important factor that couples should look definitely look out for and consider.

9. Give priority to quality over money (unless it gets too expensive)

Remember that some companies outsource their memory foam although the mattress could be assembled in the United States. It is thus advisable to look at labels that disclose as much information as possible.

Buyers should be able to know whether the product adheres to certain standards of quality where the product was manufactured. Besides looking for appropriate quality certifications, invest in a product from a reputable company.


Besides looking for the above features, be very sure of what you need in a mattress. Also, look out for companies that provide trial periods, easy returns and long-term warranties. It could take a few days to judge whether you like the mattress or not, so look for a minimum 30 day return period.
