  • Firmness: medium or firm
  • Warranty: 10-year limited

More features: dual-sided; quilted; CertiPUR-US certified; free pillows

The Roma Latex Mattress is the number one product on our list, and this did not come by accident. The mattress offers an array of exciting features designed to give its user the maximum comfort, so we had an easy choice to make. For instance, Roma uses 100% Natural Dunlop latex to manufacture this mattress, so rest assured, you are not getting any synthetic material.

Furthermore, the Roma Latex Mattress offers two different levels of support – firm and medium – accessible by a flip of your mattress. This is a very exciting option due to the possibility of your comfort preference changing over time. Also, the cover of the mattress is made from non-toxic, organic cotton that offers an amazing feel for someone who had suffered from a bad mattress.

    What are its best features?
  • We absolutely liked that this mattress is flippable. That means you can decide to use the firm or the medium side, depending on your preference. Another feature we liked is that this product is made of 100% Natural Dunlop latex without any room for synthetic materials. We also like the organic cotton cover that ensures the absence of allergies since it's made without chemicals. The cover is quilted to provide extra comfort. The two free pillows that accompany this mattress also impressed us.
    What could be improved?
  • We discovered that the manufacturer does not offer a sleep trial. This will deny potential buyers the chance to test the product before committing to it.

Thanks to the plant-based Bio-Pur® memory foam, the mattress offers cooling comfort during sleep. Also, the supportive Active Flex foam helps to maintain healthy spinal alignment.

Moreover, the inclusion of the eco-friendly Bio-Pur® in the production of this mattress makes it a huge upgrade from older Amerisleep mattresses.

The AS5 Hybrid also uses a pocketed coil system to deliver bouncy support from your head to toe, keeping your body aligned and lifted

The Layla Hybrid Mattress is another top product on our list. It caught our interest with its copper-infused foam that transfers heat away from the body quite fast, resulting in a very cool sleeping experience. Since copper is naturally antimicrobial, this mattress’s copper gel forms a barrier that resists odor-causing bacteria, keeping you sleeping fresh.

Furthermore, the Layla Hybrid Mattress features one of the most advanced coil systems in the industry. The coil system delivers great edge support and provides the mattress the flexibility it needs to comfort an adjustable base without hassle.

  • Warranty: 10-year

More features: quilted; high-density; made in the USA; 120-night risk-free trial

It uses one zippered enclosure to house three interchangeable foams.

With the 1.5-inch quilted comfort surface layer, you get exceptional airflow for a cool night’s sleep, while the 2-inch intermediate layer of foam provides a gentle transition to the high-density base foam, which is firmer.

  • We don’t like that this mattress is not flippable, although you have the option of rotating the foams. However, in our opinion, it takes more time and energy to rotate the foams.

Things to Consider

Even though you now know about the best mattresses that won’t sag, it’s not enough to buy the right product for yourself whenever you decide to head to the market. Luckily for you, we’ve developed a comprehensive buying guide to help you buy the best firm mattress that won’t sag.

Advantages of a mattress that won’t sag

5 Best Mattresses That Won’t Sag for Cozy and Comfortable Sleep

Away from the nightmare of sleeping with a sagging mattress, a mattress that won’t sag offers several health and mental benefits. We will discuss them below:

  1. If you have chronic pain or other preexisting health conditions, a mattress that won’t sag will provide you a comfortable space to relieve your condition; it won’t worsen it.
  2. It will prevent you from having any trouble sleeping
  3. It will protect your spine from being misaligned, thus preventing neck and shoulder pain.

Features to think about before you buy a mattress that won’t sag

Are you ready to head to the market to buy a mattress that won’t sag? Well, congratulations, that’s lovely. Below, we will detail the features that you must consider before choosing so that you can buy the best mattress that won’t sag in the middle.

Sizes

The first factor to consider when buying a new mattress is the size. The reason is not farfetched; you want a mattress with the right size for the user. If you end up buying the wrong size, you’ll hardly get the comfort you sought before buying the product. This is why you must pay great attention to the size of the mattress you’re buying.

Apart from considering the user, you should also consider the space in your bedroom. You don’t want to buy a mattress that takes all the space in your small room. There are different sizes of mattresses, including Twin, Twin XL, Full, Queen, King, Cal King, and Split King.

You can see that the best mattresses on our list — Roma Latex Mattress, Amerisleep AS5 Hybrid mattress, Layla Hybrid Mattress, Rubix Mattress, and Titan Mattress — have these sizes. You have the luxury of choosing the best size that suits you. We advise that you choose a mattress with a length of at least 10—15cm longer than the tallest person that will be sleeping on it.

Height

Height is another factor that requires consideration when buying the best mattress that won’t sag. It determines the distance between the top layer of the mattress and the floor even when you use a frame to hold the mattress.

The 9-inch Roma Latex Mattress has a good size for anyone who loves their mattress to have some good height. If you want a taller option, the Titan Mattress is your guy with its 11-inch height.

Material

Another factor that can’t be left out of consideration in the struggle to acquire a mattress that won’t sag is the material of the product. Like every other product, the material of a mattress is the engine of the product. Without the right material, there’s a 99% mattress will sag.

Gone are those days when mattresses were made up of a coil base with a padded top. Today, we now have various materials that are used to manufacture mattresses.

Different materials have different levels of resistance to body impressions and sagging. Let’s delve into the world of mattress materials.

Innerspring — This mattress material is a classic style made with a single continuous coil. It is usually firm, supportive, and bouncy. With tall sections of steel coils, innerspring gives the “old-school” vibe. Although they are said to last up to 10 years, the spring’s tension may start going down after 5 to 6 years, resulting in an irredeemable sag.

This material is ideal for people who need major support, including heavier sleepers, stomach sleepers, and back sleepers.

Pocket Coils — Instead of using a single continuous coil, what you find in some mattresses is a system of individual fabric-encased coils. The Rubix Mattress and Titan Mattress are examples of such mattresses. The coils independently respond to motion, making the mattress more resistant to sag. A mattress made from pocket coils can be the best spring & coil mattress that won’t sag.

Foam — It has two varieties; memory foam and polyfoam. They both offer exceptional pressure relief because they conform to the shape of for body. The memory foam, especially, is known for its deep contouring hug and slow response to pressure. With memory foam, sensitive spots such as the shoulders, lower back, and hips enjoy a great amount of pressure relief.

However, softer foams may stop regaining their shape completely and start to sag within five years. Another disadvantage of memory foam is that it tends to absorb body heat which can be a problem for someone who naturally sleeps hot. But most brands now infuse cooling agents such as gel, graphite, or copper into their memory foam materials. The copper-infused Layla Hybrid Mattress is a good example of mattresses with cooling agents.

Besides, the memory foam’s deep contouring hug is a good thing for side sleepers.

Latex — This is an all-natural material. If you don’t fancy synthetic materials, Latex is the material you go for. It quickly responds to pressure, making it bouncy and lively. Also, this material is naturally cooling, making it a good option for people who sleep hot. Latex is a little more durable than memory foam. If you’re an eco-friendly person who prefers organic materials, then a mattress like the Roma Latex Mattress is right for you. Moreover, latex’s natural bounce helps several groups of sleepers, but it helps combo sleepers the most.

Hybrid — As its name suggests, this material combines two or more materials. It is usually made with a foam or latex topper and a coil base. Hybrid shouldn’t be confused with the innerspring because it has a more “balanced” feel. The thickness of a hybrid mattress’s comfort layer determines the durability of the mattress before sagging. The Amerisleep AS5 Hybrid mattress and Layla Hybrid Mattress are excellent examples. They serve combo sleepers and back sleepers well.

With proper construction and support, mattresses created from any of these materials should serve you for many years without sagging. However, they last longer than one another.

Firmness

What is firmness in this context? It tells how soft or hard a mattress feels when you lie down on it. Different mattresses have different firmness levels. For instance, you can find soft, medium, or firm mattresses on the market. Some models even offer firmness options like a very firm, extra-soft, medium-firm, extra-firm, amongst others.

We advise that you choose the firmness level based on your body weight and regular sleeping position. Apart from making your sleep comfortable, it can help to prevent your mattress from premature sagging because the surface tension of the mattress will be well suited to your body weight.

Furthermore, we recommend that sleepers over 230 pounds opt for extra-firm, firm, or medium-firm to give the extra surface tension needed to keep you in good shape. There’s this general belief that softer mattresses sag quickly while firm ones do not. However, this is not true. The mattress’s firmness does not determine how quickly the foam may start to sag. So, you should choose a firmness level that is suitable for you without counting durability as a factor.

Flippable mattresses like the Roma Latex Mattress and Layla Hybrid Mattress give you the option of flipping to either side of the foam. Both sides usually have different firmness levels.

Warranty

5 Best Mattresses That Won’t Sag for Cozy and Comfortable Sleep

Warranty is always a good thing to have on a new product. It assures you that your investment is safe. As you can see from the mattresses on our list, many brands provide amazing warranties to cover indentations and sagging. However, different brands have different warranty policies.

For example, some policies only cover sagging up to a specific depth. You should choose a warranty that covers sagging from below .75 inches since indents below this depth can change the mattress’s structure and support.

Some generous manufacturers also offer an at-home sleep trial of up to 90 days, giving you enough time to get comfortable with the mattress and decide if it can serve you for years to come.

Ten years is the most popular warranty period amongst the best mattresses, as you can from our list of best products. Only the Amerisleep AS5 Hybrid mattress offers an astonishing 20-year warranty. The mattress also offers a 100-day sleep trial. Moreover, the Rubix Mattress and Titan Mattress both offer a 120-day sleep trial.

We advise you to only buy a mattress with at least ten years warranty and a 100-day sleep trial. We also recommend that you buy directly from the company because some warranty policies do not apply when you buy from third-party stores.

Accessories

Not many accessories come with mattresses. However, the most popular ones that do so are pillows. The best mattresses provide free comfortable pillows to complement your equally comfortable mattress. The pillows help to save your neck from pain. Roma Latex Mattress and Layla Hybrid Mattress are some products that care about your comfort and provide free pillows. It’s a big plus to go for a mattress that offers free pillows.

FAQ

Is the frame important to keep the mattress from sagging?

A leading cause of sagging mattress is a poor foundation. When the mattress continues to sit in a bad space, it takes little time before it starts reacting and sagging. Improper foundations such as bed frames without slats and the floor can cause your mattress to sag quickly. So, to answer your question, a frame is very important to keep the mattress from sagging. The frame holds the mattress in place and gives it the support it requires to maintain its structure.

Is there a weight limit for a mattress?

Make no mistake about this. The weight of the sleeper affects the mattress. That is why we advised heavier sleepers earlier to consider firm and extra-firm options. When a heavy sleeper sleeps on a soft mattress, it’s not good for any of them; they’ll both suffer. Some companies put a weight limit on their mattresses while others don’t, but standard mattresses support people who weigh around 230 to 250 pounds. Even when there’s no stated weight limit, you should consider your weight to get a mattress with the right firmness level for you.

Are mattresses that won’t sag very firm?

As we mentioned before, the level of a mattress’s firmness doesn’t determine if it sags or not. Even though firm mattresses are naturally stiffer than soft ones, they have no guarantee of lasting longer. For example, a firm mattress with the same construction, a soft mattress won’t last longer than its softer counterpart just based on firmness. Of course, mattresses that won’t sag can be very firm, as you can see from the products on our list, but the level of firmness is not responsible for the mattress sagging or not. In fact, you can easily find a reliable soft mattress that won’t sag.

Our verdict

After a thorough review of the best five mattresses on the market, you can agree with us that the top products are designed to provide you maximum comfort. Despite their different materials, the mattresses are designed to give an exceptional sleep experience. In our opinion, the Roma Latex Mattress is the best mattress that won’t sag thanks to the 100% Natural Dunlop latex content, making it easily our Editor’s Pick. It’s not only designed with organic materials, but it also offers you two different firmness levels that you can get by only a flip of the mattress.

Just behind this product is the Amerisleep AS5 Hybrid mattress, a Premium Pick that uses the Bio-Pur® material to relieve pain and pressure points. In addition to those two products, our Best Value pick – Layla Hybrid Mattress – combines an advanced coil system and a copper-infused foam that resists bacteria.
