An inappropriate mattress density affects your sleep and general health. Clients often buy the wrong mattress because they don’t understand how to choose the right one. Foam density is the measure of the amount of material a manufacturer compresses into a specific amount of space. Mattress density is expressed in pounds per cubic foot (lb/ft³ ). Dense mattresses have more material packed into their form that offers better sleep support.

Different Mattress Densities In The Market

Manufacturers make three densities of foam mattresses. Once you learn which density works for you, look for an ideal mattress on Slumber Search

Low Density

A 3 lb/ft³ is the measure of a low-density foam mattress. The mattress feels soft when you sleep on it. It’s an affordable option for clients who are on a tight budget and lightweight sleepers who weigh less than 130lbs. Soft mattresses are excellent for side sleepers because they support a natural body’s curves. These mattresses tend to spring back faster, they offer comfort for light sleepers who move a lot as they sleep. These mattresses offer little support and affect your sleeping posture since they sink easily, particularly if you’re heavy. Low-density mattresses have a 5-year lifespan. 

Medium Density

Medium-density mattresses have 4- to 5 lb/ft³ measurements. They are a perfect blend of warmth, support, comfort, and durability.  Such mattresses subtly resist your weight and sink mildly when you lie on them. Their buoyancy contours a body and relieves pressure points. This density is suitable for people who weigh 130 to 230lbs. Medium-density mattresses offer excellent back support so they are ideal for side sleepers, couples, and people who have mild back issues. Medium-density mattresses last for 7 to 8 years.

High Density

High memory foam mattresses have 6 lb/ft³ measurements and above. They are the most commonly recommended mattresses because of their comfort. Their foam and latex offer stiff and firm back support that also conforms to take your body’s shape as you sleep. These mattresses relieve joint pressure, prevent backaches and improve blood circulation. High-density mattresses are ideal for sleepers who weigh 230lbs and above. Side sleepers, people who move a lot in bed, couples, and individuals with back pain. Notably, such densities reduce airflow and make a mattress very warm. High-density mattresses last for 9 to 10 years.

Why Mattress Density Is Important

Density affects the firmness, lifespan, comfort, stability, and off-gassing of a mattress. Density also relieves body pain and affects your general well-being. High-density mattresses are also more expensive. Off-gassing refers to the odors a foam mattress omits after you unpack it. High-density mattresses take longer to clear off-gas than low-density ones. 

According to the Sleep Foundation, these odors don’t pose a serious threat to your health but scientists recommend natural and organic-made mattresses. 

If you have allergies like asthma, an off-gassing mattress causes headaches, dizziness, and nausea. In severe long-term exposure to these odors, people experience memory loss. Other chemicals like polyurethane are combustible and the law requires manufacturers to make flame-retardant mattresses. The best way to get rid of these odors is to let your mattress breathe for some days before use. 

Mattress density affects heat retention. A low-density mattress sinks and builds heat around your body. Better mattress densities keep you on top and allow air to circulate to keep you cool. People who hate sleeping hot prefer mattresses that have better air circulation like medium and low-density ones. Lastly, foam mattresses are great for motion isolation. Some densities are ideal for couples who are sensitive to a partner’s movements in bed.

What To Consider When Choosing Mattress Density

You need to consider your weight, your favorite sleeping position, and any medical conditions like back pain. You should also consider a mattress’ off-gassing and temperature retention to ensure comfort as you sleep. Lastly, you need to factor in how much you’re willing to spend on a mattress.

Conclusion

The density of your mattress influences its firmness and affects the quality of your sleep. Manufacturers make low, medium, and high-density mattresses. You need to choose a comfortable density that resolves any sleep-related medical conditions.
