Can Latex Mattresses Really Prevent Sagging?

When it comes to mattresses, one of the most common complaints is sagging. Over time, mattresses can lose their shape and support, leading to uncomfortable and restless nights. This can be especially frustrating if you’ve invested in a high-quality mattress, only to have it start sagging after a few years.

But what if there was a solution to this problem? Enter latex mattresses. These mattresses have gained popularity in recent years for their ability to provide a comfortable and supportive sleep experience. But can they really prevent sagging? In this article, we’ll explore the science behind sagging mattresses and whether latex mattresses are the answer.

Why Do Mattresses Sag?

Before we dive into the effectiveness of latex mattresses in preventing sagging, let’s first understand why mattresses sag in the first place.

Natural Wear and Tear

Like any other product, mattresses are subject to wear and tear over time. As we sleep on them night after night, the materials in the mattress start to break down and lose their shape. This is especially true for mattresses made with lower quality materials. For example, traditional inner spring mattresses have large coils that easily breakdown, especially in less expensive thick mattresses. Unfortunately, these coils are just stretched to make them wider with no more coil/metal used in the structure. This causes a lot of problems.  If you buy an inner spring mattress it should be extremely heavy.  That way you know you have a lot of properly supported and constructed coils.

Poor Support

Another common cause of sagging is poor support. If a mattress doesn’t have enough support, it can start to sag in the areas where our bodies put the most pressure. This is why it’s important to choose a mattress with the right level of support for your body type and sleeping position. Poor support can mean a couple things here.

  1. The foundation – making sure the mattress is properly supported by a solid foundation is crucial.  Mattresses were originally made to work together with the box spring. The mattress would give and so would the springs in the box spring, hence the name.  However, today with much diversity in the bed frame styles, mattresses are made to stand alone, supported by a proper foundation.
  2. Cheap internal construction – so we know that the construction of mattresses can be a coil, pocketed coil, poly foam, memory foam, latex foam, gel foam, micro-coils, and more. Any combination of these can be the components that make the internal structure of the mattress. Any of these made inexpensively, using less that quality components can cause poor support.

Moisture and Heat

Moisture and heat can also contribute to sagging in mattresses. When we sleep, our bodies release moisture and heat, which can get trapped in the mattress. Over time, this can cause the materials to break down and lose their shape, leading to sagging. This is primarily an issue with memory foam mattresses.

Can Latex Mattresses Prevent Sagging?

Now that we understand the causes of sagging in mattresses, let’s explore whether latex mattresses can actually prevent it.

Natural Resilience

Latex mattress

One of the main reasons why latex mattresses are known for their ability to prevent sagging is their natural resilience. Latex is a highly durable material that is able to maintain its shape and support over time. This means that even after years of use, a latex mattress is less likely to sag compared to other types of mattresses. This is because latex is rubber. Just like your tires on your car. Very durable. You want to opt for the 100% natural latex here, because synthetic latex will break down more quickly because it has less actual rubber in it.

Consistent Support

Latex mattresses also provide consistent support throughout the entire mattress. This is because latex is able to distribute weight evenly, preventing any one area from bearing too much pressure. This helps to prevent sagging in specific areas of the mattress.

Moisture and Heat Resistance

Unlike other materials used in mattresses, latex is naturally resistant to moisture and heat. This means that it won’t break down as easily when exposed to these elements, helping to maintain its shape and support for longer.

High-Quality Materials

Latex mattresses are typically made with high-quality materials that are designed to last. This means that even after years of use, the materials in a latex mattress are less likely to break down and cause sagging.

Other Benefits of Latex Mattresses

Aside from their ability to prevent sagging, latex mattresses offer a range of other benefits that make them a popular choice among consumers.

Pressure Relief

Latex mattresses are known for their ability to provide pressure relief. This is because they are able to contour to the body, providing support where it’s needed most. This can be especially beneficial for those who suffer from back pain or other body aches.


Latex is a naturally hypoallergenic material, making it a great choice for those with allergies or sensitivities. It is resistant to dust mites, mold, and mildew, making it a healthier option for your sleep environment.


Latex mattresses are also considered to be more eco-friendly compared to other types of mattresses. This is because latex is a natural material that is sustainably sourced from rubber trees. It is also biodegradable, making it a more environmentally friendly option.

How to Choose the Right Latex Mattress

If you’re convinced that a latex mattress is the right choice for you, here are some tips for choosing the right one:

Consider Your Sleeping Position

Different sleeping positions require different levels of support. For example, side sleepers may need a softer mattress to relieve pressure on their hips and shoulders, while back sleepers may need a firmer mattress for proper spinal alignment. Consider your sleeping position when choosing the firmness of your latex mattress. Design your own latex mattress. Click here 

Look for Certifications

When shopping for a latex mattress, look for certifications such as the Global Organic Latex Standard (GOLS) and the Global Organic Textile Standard (GOTS). However pricier, these certifications ensure that the latex used in the mattress is organic and sustainably sourced.

Test It Out

Just like with any other mattress, it’s important to test out a latex mattress before making a purchase. Find a showroom near you where you can test it out. This will give you a better idea of the level of support and comfort it provides.

Other Tips for Preventing Mattress Sagging

While latex mattresses are known for their ability to prevent sagging, there are some other steps you can take to prolong the life of your mattress and prevent sagging:

Rotate Your Mattress

Rotating your mattress every 3-6 months can help to distribute wear and tear evenly, preventing sagging in specific areas.

Flip Your Latex Layers

A lot of latex mattress manufacturers construct their mattresses so you can get inside the mattress and rotate the layers to change the firmness level. This also gives you the option to flip and rotate individual 3-inch latex layers for an extended life.

Use a Mattress Topper

A mattress topper can provide an extra layer of support and protection for your mattress. This can help to prevent sagging and extend the life of your mattress.

Invest in a High-Quality Mattress

Lastly, investing in a high-quality mattress from the start can help to prevent sagging in the long run. While it may be tempting to opt for a cheaper option, a high-quality mattress will last longer and provide better support, ultimately saving you money in the long run.

So, do Latex Mattresses Sag?

The short answer is yes, latex mattresses can sag.  However, there are some important facts to note. Typically, the latex mattresses that sag are made with synthetic latex and lack a proper foundation for support. They are also usually the soft latex mattresses that sag.  But if you opt for a firmer 100% natural latex mattress and properly rotate the internal layers you should have a non-sagging mattress for years. We’ve seen firm and extra firm latex layers in perfect condition after 20 plus years of use! Pro tip – if you really don’t want sag and are shooting for longevity, go for no soft layers, just medium and up!


In conclusion, latex mattresses are a great option for those looking to prevent sagging in their mattress. With their natural resilience, consistent support, and resistance to moisture and heat, latex mattresses are able to maintain their shape and support for longer compared to other types of mattresses. By choosing a high-quality latex mattress and taking proper care of it, you can enjoy a comfortable and supportive sleep experience for years to come.
