Best Mattress That Dont Sag

We’ve all stayed at hotels with mattresses that seep to the floor once we lay on them. If you sleep on a sagging mattress at home, its time to start looking for a new one. Even a slight sag can have detrimental effects on your sleep quality and health. There are plenty of affordable mattresses that will not sag over time thanks to their high-quality memory foam and coils. Finding the right mattress is tricky, and it’s easy to be deceived by the price. Fortunately, we did our homework and found the best mattresses that don’t sag. 

Factors to Keep in Mind While You Are Shopping

When looking for a new mattress, you must consider various factors, not just the possibility of the mattress sagging. For example, certain mattresses are designed for side sleepers, whereas others are better suited for back sleepers. On top of maintaining their shape, the mattresses we have presented below offer high-quality support paired with advanced technology. While you don’t want your mattress to sag, you must also consider other characteristics that could affect your quality of sleep, such as the level of built-in cooling. Think about what is important to you while you sleep and keep that in mind as you search for your next mattress.

We handpicked the best options for those who want to avoid purchasing a mattress that will sag after a few years of use. While researching, we considered the price, relative certifications, and customer reviews. We also looked at the length of the warranty and whether the brand offered a free trial period. The below brands offer some of the best bang for your buck, without compromising quality:

The Side Effects of a Sagging Mattress

Unbeknownst to some, a sagging mattress can affect a lot more than the quality of your sleep. As a mattress ages, it usually starts to sag in the center, or wherever the most weight is concentrated. This sagging can throw your body out of alignment, causing lower back pain, sore muscles, and stiffness in your neck. If you’re not sure whether your mattress is sagging or not, you can use a measuring tape to measure the ends and then compare those measurements to the width of the center.

Getting a bad night of rest triggers a domino effect. The next day, you’ll be more prone to mood swings, daytime drowsiness, and headaches. Sleep deprivation also has long-term effects that are more serious, such as anxiety and depression. All of this, including body pain and aches, is caused by a sagging mattress. For this reason, it’s important to replace your sagging mattress with one that is more durable and built with high-quality materials.

Can You Fix a Sagging Mattress?

The best answer is no, you can’t fix a sagging mattress. While there are a few solutions that offer short-term relief, it is not practical to try and repair your sagging mattress with the hopes that you will be able to sleep comfortably. Some DIY techniques include placing pillows underneath the mattress, flipping the mattress regularly, and buying a mattress topper. The hassle of having to constantly alter your mattress is not worth it. In fact, simply replacing your mattress is often more affordable in the long-run. And don’t forget about the risk of botching a DIY job and causing more sagging and thus, more pain.

We ranked the Helix mattress as one of the best mattresses this year. The reason that the Helix mattress is so popular is that it’s custom-designed for your body type and sleeping habits. Helix offers an assortment of different mattress styles, including a 14-inch luxury hybrid option, an organic mattress, and their standard Helix Mattress. It’s also important to point out that every mattress comes with a 10-year warranty and a 100-night risk-free trial. Helix makes every mattress in the United States to ensure that the mattresses meet rigorous quality standards.

Depending on your sleep quiz results, Helix will either offer a mattress with a soft, medium, or firm feel. No matter what firmness level best suits you, there’s no need to worry about sagging in the future. The bottom of the mattress is constructed with a DuraDense foam layer that not only provides support but also increases the durability of the mattress. In addition to the support layer, there’s also a layer of wrapped coils that limit motion transfer and contour to the shape of your body. When it comes to customization, Helix is one of the best mattress brands in the industry.


Plushbed’s mattresses have been featured on several leading publications and networks, including Good Morning America and Vogue. Perhaps one of the “greenest” mattresses on the market, a Plushbed is made with GOTS certified organic cotton and certified organic latex. These certifications are a token of Plushbed’s belief in quality and sustainability. Cheap mattresses, often filled with foul-smelling toxins, are the first to sag. Plushbed mattresses, on the other hand, can last for years. The brand even offers a 25-year warranty in case your mattress does not hold up as it should.

While the natural and organic mattresses are some of Plushbed’s most popular products, they also offer memory foam, sofa bed, and RV mattresses. When it comes to the natural and organic mattresses, there are three options to choose from: The Botanical Bliss, Luxury Bliss, and Natural Bliss. All the mattresses boast natural latex and multiple support layers. The most affordable of these options, the Natural Bliss, is 100% vegan and has no synthetic blends or chemicals. Not only are you getting quality when you buy a Plushbed product, but you’re also getting an eco-friendly product that represents Plushbed’s core values.


Just because a Puffy mattress feels like a cloud, doesn’t mean it sags like a cloud. Over 8,000 happy customers have left reviews about their positive experience with one of the three Puffy mattresses: the standard Mattress, Lux Mattress, and Royal Mattress. Every Puffy mattress comes with a firm core support layer that prevents sagging and provides your body with the perfect amount of comfort needed for a good night of sleep. There’s also a unique Cooling Cloud™ layer that helps regulate your body temperature, both in the winter and in the summer.

If you opt for the most popular option, The Lux Mattress, you’ll get more advanced features. This model comes with extra spinal support, a luxury cover, and a high-density transition comfort layer. Since every Puffy mattress is covered under a lifetime warranty, there is no need to worry about sagging. You’ll also get a 101-night free trial to ensure that the mattress is right for you. No matter what type of sleeper you are, the Puffy mattress can help you get the much-deserved rest that you’ve been looking for.


DreamCloud is one of few brands that offer a luxury mattress without the sky-high luxury price tag. The DreamCloud model, the most popular pick, starts at just $899. You also have the option of adding a premium topper for an additional cost. Even though there are cheaper mattresses on the market, you won’t find many with a comparable amount of features for the price. The DreamCloud mattress has a quilted cashmere top layer that will keep you cozy no matter what time of the year it is. Right underneath the cover is a gel memory foam layer that molds to the shape of your body. This high-quality gel memory foam won’t permanently sag compared to the cheap foam used by competing brands.

All the five layers are supported by a base layer, ensuring that the mattress maintains its shape and doesn’t deteriorate over time. On a scale between 1 to 10, the DreamCloud mattress falls on 6.5 with respect to firmness level. A little bit of firmness is important because it keeps your body from sinking into the mattress too deeply and experiencing discomfort. And thanks to its wrapped coil system, the DreamCloud mattress offers remarkable motion isolation. You can get in and out of bed without your partner noticing. If you want a premium mattress but don’t want to break the bank, the DreamCloud is a strong contender for you.


The last mattress to make our list is the Bear mattress. This mattress brand has received extremely positive press – it was rated the best mattress in a box by Bravo and the best mattress for back pain by Business Insider. While the Bear mattress is a great choice for all types of individuals, the brand touts itself as one of the best options for athletes and individuals who spend lots of time on their feet. Bear offers three different mattress options: The Bear Pro, Hybrid, and Mattress. Out of the three options, the Mattress model is the most affordable.

Like the other mattresses we have reviewed, the Bear mattress has no lack of high-quality and durable materials. Even the cheapest option has a Celliant® Cover, graphite-gel memory foam, transition foam, and a bottom layer of high-density support foam. Bear uses CertiPUR-US® certified foams, which means you’ll never have to worry about toxic odors or harmful chemicals. To make sure you’re 100% satisfied with your mattress, Bear lets you try it out for 100 nights, risk-free. With its multiple layers of high-quality memory foam, this mattress will certainly maintain its shape.

Don’t Let a Sagging Mattress Ruin Your Sleep Quality

If you can hear the springs creaking when you get into bed at night, it’s time to invest in a new mattress. An investment in a mattress that doesn’t sag is an investment in yourself. Sagging mattresses can not only disrupt your sleep but also lead to long-term, chronic pain. Some might just tell you to flip your mattress over or get a better box spring, but even minor amounts of sagging can cause pain and throw your body out of alignment. All the brands we reviewed go out of their way to ensure that their mattresses are durable and offer premium support. With a mattress from one of these quality brands, you won’t have to worry about sagging again.
