Best Mattresses That Don’t Sag

Our team at Mattress Advisor is committed to helping you not only find the best mattress for your individual sleeping position and needs but also wants to assist as you find a mattress that is high quality and lasts. Therefore, we conduct an in-depth and expert review process. It is our goal to only recommend mattresses that we ourselves want to sleep on— we do this by putting each mattress through a 6-point testing procedure and 8-point evaluation process. 

During the testing process, we assess and evaluate factors such as motion transfer, responsiveness, edge support, sleep trial period, firmness options, body heat mediation, breathability, return policies, and so much more. Then, we assign scores related to performance. This helps you effectively identify the mattress manufacturer and associated products that are best for you and your sleep style.

This bed is also heralded for its ability to sleep cool and remain breathable all night long. It’s top layer is cool to the touch and it also scores well for responsiveness, spine alignment, and motion transfer

Offering medium-firm to firm support, the Avocado is a great option for back sleepers and stomach sleepers who care about the environment and wish to be eco-conscious when making a decision about a new bed

Read More: Best Organic Mattresses

This organic dunlop latex mattress sleeps cool and while Avocado is a more expensive mattress option, the fact remains that you are making an investment in durable, long-lasting, all-natural materials that are high quality

The Avocado has an inner coil system with top layers made of latex. As such, the mattress is highly responsive but will not be as contouring or as plush as what you may experience with an all-foam bed. Therefore, if you want a softer and more cushioning experience, it may be wise to buy the add-on Euro pillow top for some extra bouncy comfort. 

Finally, the Avocado also offers a 25-year warranty and a sleep trial that lasts an entire year.

Buyer’s Guide: Best Mattress That Doesn’t Sag

We are well aware that shopping for a mattress can feel like a big job, especially when you want to ensure you are buying a new bed that is high quality. In this guide, we will discuss 

How to Prevent a Saggy Mattress

Nothing is more frustrating than lying on a mattress that is caving in on itself. And sometimes, this is due to the fact that, as sleepers with unique body types, we all have certain habits. Mattresses, ultimately, tend to deliver contouring to our bodies. This means that over time, it is possible for indentations in the cushioning to become visible, which compromises the ability of the mattress to effectively support you in your sleep position

However, it is possible to prevent your mattress from sagging. If you have recently purchased a new bed, consider following some of these tips. 

Firstly, make an effort to switch up your sleep position every now and then. This means if you sleep alone, make a conscious effort to sleep on the left side of the bed one night, the middle of the bed another night, and then the right side of the bed after that. If you happen to sleep with someone else, swap the sides that you sleep on weekly so that you are both placing pressure on different parts of the bed regularly.

Another great tip is to flip or rotate your mattress as this will definitely prevent sagging from setting in. Now, keep in mind that flipping might not be an applicable strategy to all mattress types. Depending on the type of new bed that you buy, your mattress might only have been manufactured for a sleeper to sleep on one side. However, all mattresses can be rotated. If you have a mattress that is flippable, rotate your mattress every three to six months. And if you are able to flip your mattress, do this every six months as well.

Next, a box spring can also increase the longevity of your mattress. Now, not all mattresses require this, but the simple fact is that a box spring will help your mattress in the long run. It is also very important to use a box spring if you make the choice to buy an innerspring, two-sided mattress as this will offer higher levels of protection.

Which Mattress Types Won’t Sag?

Innerspring Mattress

Mattresses that are made from innerspring coils alone tend to be one of the worst options if you are looking to prevent sagging. If you choose this type of new bed you are going to want to invest in a product that offers low-gauge coils because they will keep their strength longer.

Memory Foam Mattress

If you decide to purchase an all-foam memory foam bed, it is imperative that you choose a new bed that has high-density memory foam or high-density polyfoam. Plush memory foam mattresses that have lower density foam used in their manufacture will be more likely to sag. 

Latex Mattress

Latex mattresses have become increasingly popular in recent years and with good reason. These beds are very comfortable, offer superb contouring and cushioning, and deliver bouncy support. Additionally, latex is known for its durability and strength. Because latex beds are so strong, they are unlikely to experience sagging as time passes. 

Hybrid Mattress

Comprised of memory foam, latex foam, and innerspring coils (or any combination), hybrid mattresses deliver multiple comfort layers and great support. However, what makes a hybrid mattress likely or unlikely to sag is really centered on the quality of the bed itself and the materials used in its manufacturing process. 

High-density memory foam, latex foam, and the use of low-gauge steel springs will make sagging less likely. On the flip side of this, high-gauge innerspring coils and low-density memory foam can reduce the lifespan of your mattress and make it less durable. 

How to Fix a Sagging Mattress

We realize that a new mattress can sometimes be an expense that you didn’t plan on and may not be able to afford right now. If this is the case, but you know that your mattress is sagging and losing support, don’t fret; there are ways to fix a sagging mattress and extend its life to last until you can buy a new mattress

One easy tip is to make sure your mattress is supported by a box spring, and not by a slatted bed frame. Or, if you don’t want to buy a box spring yet, just make sure that the slats in the frame are not farther than three inches apart. 

Think about using some thin plywood under your mattress. While this might impact your bed’s overall breathability, making it sleep a tad bit warmer through the retention of body heat and allows a place for mold to grow and live, this is okay as a short term strategy. 

Another idea is to buy a mattress topper—the thicker the better. In this regard, you don’t want the cheapest option and will want to purchase a topper that is comprised of memory foam or high-density latex.
