Finding your best mattress that won’t sag is vital as a sagging mattress can cause health issues, for example, back pain and other joint pains. Mattresses provide us with support for roughly 1/3rd of our life, while we sleep, so you shouldn’t take any chances with a sagging mattress.

In this guide, we’ve looked at the ideal features for a top-quality soft or firm mattress that won’t sag. The type of mattress, such as whether or not it is hybrid in design, is vital. On top of this, the height and size, and its compatibility with your bed, is also crucial. The firmness of the mattress is very important, and some people have a different preference when it comes to how firm the mattress is. Of course, the mattress also needs to be durable, and we’ve explored durability issues and the warranty of the mattress in each of our reviews.

Top 10 Mattresses that Won’t Sag Review 2021

1.

The WinkBedEditor’s Choice

Features
  • Mattress type: hybrid
  • Height profile: 14.5 inches
  • Firmness: Soft (4.5), Luxury Firm (6.5), Firmer (7.5), Plus (8)
  • Materials: pocketed coils, 8 PCF polyfoam, 1.5 PCF polyfoam, 1.5 PCF gel polyfoam, foam-encased pocketed microcoils, cotton lumbar pad (for Soft, Luxury Firm, and Firmer versions)
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King
  • Warranty: lifetime limited

More features: SleepCalm motion isolation technology; proprietary lumbar layer; Extra-Edge support; 120-night trial

The WinkBed has a clever design and makes it to the top of our list due to the fact that it is versatile, and suitable for almost everyone.

It’s available in all of the sizes you would expect. It also has a limited lifetime warranty, and is available in a multitude of firmness designs so you can choose whether you want a soft or firm mattress.

It is prevented from sagging due to the “high-density foam and triple-tempered wear-resistant springs”. There is also extra edge support so not only does it not sag in the middle, it avoids sagging at the edges.

Seven different layers of this mattress are included. Each has its own purpose in terms of keeping the user supported and keeping the mattress breathable.

What do we love it for? The multiple layers within, providing an exceptional level of support. There is one specific layer that is designed for lumbar support making this one of the best mattresses that won’t sag in the middle, but also that provides plenty of back support.

What could be better: This is a little expensive for some. While it lives up to expectations with features, not everyone wants to spend that much.

Features
  • Mattress type: hybrid
  • Height profile: 13 inches
  • Firmness: soft / medium / firm
  • Materials: base support foam, individually encased coils, 1swirl visco-elastic memory foam, hyper-elastic TitanFlex foam, copper-infused CopperFlex foam
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King, Split Cal King, Short Queen, RV King, RV Bunk
  • Warranty: 10-year limited

More features: advanced cooling technology; up to 1,032 individually encased coils; 120-night trial

The Brooklyn Aurora Hybrid offers a hybrid design which gives plenty of support and an advanced cooling system. One of the great things about this is the fact that it has comparable features to the WinkBed mattress but at a much lower price point.

Choose between three different firmness options, all of which have over 1,000 individually encased coils to help with any issues around sagging.

It might sound like all of this would make it firm, but hyper-elastic TitanFlex™ foam gives a responsiveness and elasticity that feels great.

Luckily, the advanced cooling also means you don’t have to worry about overheating if you go for this option. It’s available in all of the mainstream sizes, too.

What makes it stand out? We really like the cooling features and functions, which means that these mattresses are great for warmer climates. On top of that, they also cost a lot less than some competing models, meaning exceptional value.

What could be better: The firmness ratings are usually on the “firm” side, so you might want to opt for something a little bit softer than you would go for with other brands.

3.

Helix PlusBest for Heavy People

Features
  • Mattress type: hybrid
  • Height profile: 13 inches
  • Firmness: medium-firm
  • Materials: DuraDense foam, XL wrapped coils, firm memory foam, Helix Dynamic foam, Ultra Dense 4 lb foam
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King
  • Warranty: 15-year limited

More features: 100-night trial; Soft Touch Design

The Helix Plus is another hybrid mattress that has a focus on big and tall people. It is 13 inches in size and designed to stop sagging even if the pressure of heavy people using it is applied. You don’t have to worry about this.

It has a medium firmness, and the ultra-dense foam gives support, but also stops it from being impacted by a larger person (or people) on top.

The latex-foam hybrid alternative material can contour to your body to give a comfortable “memory” feel.

XL springs also give that extra bit of support so you don’t need to worry about larger people using this model of mattress.

Why did it make our list? This allows larger built people to rest easy, knowing that their mattress won’t start to sag over time. We also like the firm foam design which gives excellent comfort.

What could be better: Unfortunately, it does come at an extra cost due to the fact that it is built to be exceptionally firm, even when under pressure. It is also a bit too firm for some people’s tastes, with no softness option.

4.

Awara Organic Luxury Hybrid MattressBest Organic Mattress

Features
  • Mattress type: hybrid
  • Height profile: 13 inches
  • Firmness: medium-firm
  • Materials: zoned multi-gauge pocketed coils, Dunlop latex, organic cotton and New Zealand wool cover
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King
  • Warranty: lifetime limited

More features: soft base layer with 4 reinforced handles; even weight distribution due to zoned coils; 365-night trial

You can feel at one with nature with this exceptional model of mattress made with totally organic materials. It is made out of Sri Lankan latex with an impressive New Zealand woolen cover to give a lot of comfort.

It’s available in all of the sizes you would expect and has a medium-firm design. This might be the best soft mattress that won’t sag, though. Even though the rating is not “soft”, the wool cover gives it a softer feel.

The coils within are cleverly zoned to give an even weight distribution, and four reinforced handles make it easy to install and to rotate when you need to.

The New Zealand wool also wicks away moisture and conversely to what you might expect, this is quite a cool mattress to use.

What are our favorite features? The organic materials mean that this is an excellent option for those worried what is going into their mattress. The wool is also a nice touch and gives it a softness.

What could be better: This mattress does have a slight odor to it which can linger for some time. This is common with some mattresses, and will go over the weeks, especially if you keep the room well ventilated.

5.

Layla Hybrid MattressBest Flippable Mattress

Features
  • Mattress type: hybrid
  • Height profile: 13 inches
  • Firmness: soft / firm
  • Materials: copper-gel memory foam, airflow support foam, Infinity Edge individually wrapped coils
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King
  • Warranty: 10-year limited

More features: 120-night trial; flippable firmness; washable cover

The Layla mattress won’t sag, and it has gained a very high rating due to the fact that it is flippable. We don’t mean you have to flip it periodically to keep it at its optimum level of support, either. “Flippable” means that one side is soft and one is firm, you can choose which is best for you or even alter it at different times to suit your current health condition or any back pain.

The airflow support helps to keep it cool, while individually wrapped coils offer plenty of support even for larger people.

The washable cover is a nice extra touch, and this ensures the mattress won’t get an unpleasant odor over time.

Though this is sold just as a mattress, you can buy it with a foundation from Layla, so you can buy the whole bed from the brand if you wish.

What do we love it for? The flippable design is definitely the number one benefit of this mattress. Neither side will sag over time, and you have the choice of whether you want firm support or a little more soft comfort while you are sleeping.

What could be better: The “firm” layer could be a little more firm for some peoples’ preference. This comes down to each person’s personal needs however. Also, a cheaper option would be welcome.

6.

Amerisleep AS1Best Firm Mattress

Features
  • Mattress type: all-foam
  • Height profile: 10 inches
  • Firmness: firm
  • Materials: memory foam, HD polyfoam
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King, Split King
  • Warranty: 20-year limited

More features: open-cell design; cooling foam and cover properties; 100-night trial

Are you looking for a firm mattress that won’t sag? The Amerisleep could give you exactly that option.

This is an all-foam mattress which has memory foam as well as polyfoam in the design. It also has an open cell design to help with coolness.

The design is pretty slimline at 10 inches, compared to some of the other options on this list which are 13 inches. It gives a very firm feel overall and some people with back issues prefer this level of support.

A 100-night trial and 20-year warranty make this mattress even more of an appealing option.

Why did it make our list? If you are looking for a firm model this could be ideal. It has a responsive foam design which a lot of people really enjoy, or even need to get the right level of support from their mattress.

What could be better: For a foam model this is pretty breathable and cool, but not quite as good as some hybrid options. The thin yet firm design is not ideal for everyone.

7.

Spindle Natural Latex MattressBest All-latex Mattress

Features
  • Mattress type: all-latex
  • Height profile: 10 inches
  • Firmness: medium / firm
  • Materials: latex, eco-wool batting
  • Sizes available: Twin, Twin XL, Full, Queen, King
  • Warranty: 10-year limited

More features: GOTS and Oeko-Tex certified; 365-night trial

Another organic model of mattress made out of latex, with eco-wool batting.

It manages to avoid VOCs, chemicals that are flame retardant or synthetic materials, and you can see why this is so popular.

This is a spindle mattress, and there is no denying the fact that spindle divides opinion, even the manufacturers claim that this is not for everyone.

It comes in the mainstream sizes of bed, and has a 365 night trial so you don’t have to worry too much about whether it will be suitable for you.

The manufacturers have GOTS and Oeko-Tex certification for this model of mattress, which means they are ecologically sound and good for the environment.

The manufacturer’s site has a clever questionnaire to help you work out whether you want the soft, medium or firm options.

Why did it make our list? This is available in different firmness options so that you can get the right model for you. It doesn’t sag, and it is good for the environment with no synthetic materials.

What could be better: The spindle design isn’t for everyone. Some people simply don’t enjoy the texture. However, no mattress is to everyone’s preference. The organic materials also make this quite an expensive model.

8.

PlushBeds Luxury Bliss MattressBest Luxury Mattress

Features
  • Mattress type: hybrid
  • Height profile: 12 inches
  • Firmness: medium / med-firm
  • Materials: pocketed coils, organic Dunlop latex, organic cotton cover quilted with organic wool
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King, Split King (2)
  • Warranty: 24-year limited

More features: GOTS certified organic cotton cover; 100-night trial

Plush beds believe that the answer to firmness and quality is a lack of chemicals. The manufacturer makes some bold claims about their undeniably quality mattresses; “Say goodbye to chemical-filled sagging foams, and say hello to luxurious, organic sleep on an organic hybrid latex mattress for you & your family.”

The organic dunlop latex and cotton cover do a fantastic job of keeping this mattress firm, it is one of the best mattresses that won’t sag in the middle or around the sides, and the 25-year warranty gives even more protection for people purchasing it.

Materials include Global Organic Textile Standard approved wools and cotton, so they are high-quality as well as ethically sourced.

There’s a 100-night trial, and this is a medium/medium-firm mattress.

Why is it special? As well as being ethically sound, this mattress gives decent value and a responsive design. The cotton gives a comfortable layer on top, while coiled springs conform to the shape of your body.

What could be better: This isn’t the best mattress for people who are looking for something to help them stay cool. It can run a little hot.

9.

Bear Hybrid MattressBest Cooling Mattress

Features
  • Mattress type: hybrid
  • Height profile: 14 inches
  • Firmness: medium-firm
  • Materials: high-density support foam, pocketed coils, comfort foam, cooling-gel foam
  • Sizes available: Twin, Twin XL, Full, Queen, King, Cal King
  • Warranty: 20-year limited

More features: 100-night trial; Greenguard Gold certified, Celliant Infrared Yarn Technology

The bear hybrid is a very thick and high model of mattress with a 14-inch design, and within this it packs a number of layers including a cooling-gel foam. This helps it to stay very cool and means that the bear hybrid is a great choice for hotter climates.

The fiber top is hand quilted with plenty of comfort, and a foam, combined with cooling gel, is a good choice for all sleep positions. There is another type of foam, “transition foam” which helps with the airflow, too.

The edge coil system means a bouncy and firm feeling even at the extremes of the mattress.

This is a durable and comfy model with a medium-firm design and has a great responsiveness to go with the coolness.

It is Greenguard Gold certified for quality and materials and comes with a 20-year warranty.

What stands out? The coolness is undeniably one of the huge positives for this mattress. It has a hybrid design which does a good job of being breathable, but still gives plenty of support.

What could be better: It’s on the soft side of medium-firm, but this is about personal preference. The break in period is also quite long for a mattress.

10.

Idle HybridLongest Trial

Features
  • Mattress type: hybrid
  • Height profile: 14 inches
  • Firmness: medium / luxury firm / medium and luxury firm on different sides
  • Materials: contouring foam, cooling buoyancy foam, transition foam, pocketed coils
  • Sizes available: Twin, Twin XL, Full, Queen, King, Split King, Cal King
  • Warranty: lifetime limited

More features: 1,000 smart support coils; natural fire-resistant barrier; flippable mattress; 18-month trial

Maybe you are prone to changing your mind, or maybe you just want a long time to make your decision. The 18-month trial on this is the top benefit of the Idle hybrid.

As well as this, it includes multiple types of foam to go with the pocketed coils and give support and comfort.

It is a flippable model, meaning that you can choose between a softer firmness on one side and a harder on the other.

The 1000 quantum wrapped coils give this a great responsiveness.

The anti-sag features are good, and the manufacturer offers a lifetime warranty, even if there is a body impression left on the mattress you can still make a claim. Some manufacturers do not allow this.

It’s fairly good value for money and the flippable design is always a bonus.

What do we love it for? The fact that you can flip this to give you your ideal mattress firmness is great. On top of this, the unprecedented 18-month trial period means you can test it out longer than its competition.

What could be better: It doesn’t do a great job of staying cool, and the edge support could be a little better in an ideal world.

Things to Consider

Buying a mattress is not something most people have done in recent years, and there is no denying the fact that the technology behind them has come a long way. There are an incredible amount of options now, and some key improvements that make it possible to get decades of use out of a mattress rather than having to constantly replace it. It’s an investment.
Our buying guide is designed to help you to make the right choice.

What kind of mattress are less prone to sagging?

Hybrid and latex mattresses are less prone to sagging than competitors. It comes down largely to the quality of materials. For example, if you have a mattress with low quality coils these can start to sag either in the middle or around the edges.

Hybrid models often use responsive foam and latex, and the buoyancy of these gives extra support to prevent sagging.

Features to consider before you buy a mattress

What are some of the features to think about before you make your purchase?

Type of mattress

The type of mattress is one of the biggest considerations. Some people prefer a foam or spindle mattress, but a lot of the best mattresses for anti-sagging are hybrid models including layers of foam, latex and other materials.

Materials

As you will see from reading our mattress reviews, there are so many different materials that get used in the manufacture of mattresses. Memory foams, cooling foams and even “transition” foam are all popular, as well as latex materials, and even coatings such as cotton or lambswool, as found in the Awara Organic Luxury Hybrid Mattress.

The quality of materials is vital, and the ethics of where the materials are sourced can be a big deal, too. We’ve only recommended ethical mattresses.

Mattress profile height

The height of the mattress is commonly between 10 and 14 inches. Though they will fit your bed based on what size it is (queen, king, etc.) you might want to think about how high you actually want the mattress to be, too. A 14-inch model might give more spring, or more support for a larger individual using the bed.

Mattress firmness

Firmness is another vital buying consideration. Some of the mattresses are flippable meaning that you can choose between a firmer and softer side. Most of the products on this list are either medium or medium-firm in their rating, as this helps them not to sag.

Different people have their own preferences when it comes to firmness and how much support and hardness they want on the mattress. For back problems, you might want a firmer mattress that still contours to your body.

Sizes available

Top 10 Comfy and Durable Mattresses That Won't Sag for Years to Come

We’ve mentioned on all of the mattresses reviewed which sizes are available. Size needs to be matched up with the base or bed frame that you have or are planning to buy. Most mattresses come in twin, king, and queen sizes, but some other sizes such as California King might be harder to come by, and you may have less choices of which mattress to buy.

Warranty and sleep trial

It is common for mattresses to come with very long warranties. A 10-year warranty sounds like an incredible amount of protection, but products like the PlushBeds Luxury Bliss come with much longer warranties. In this case, 25 years.

Price

You need to match up your mattress to your budget. Luckily, there are some good value models such as the Brooklyn Aurora Hybrid, giving plenty of quality without breaking the bank. As you delve into some of the more extravagant materials such as lambs wool, you may find that the products cost a little more. Remember that they might last you decades, though.

FAQ

By its nature, foam will sag on a long enough timeline. It is not the material that is the most important thing here, though. It is the quality of the foam that is vital. As long as you get a solid, high-end memory foam or other foam product, the mattress should not sag for as long as you use it.

Hybrid mattresses combine a number of different materials, split into layers. Commonly, memory foam, latex, and gels are used alongside the spring system that sits underneath. Hybrid mattresses can allow manufacturers to add more solidity and layers to address sagging or comfort.

Latex is a very long-lasting material. This doesn’t automatically make them the best choice though, as it boils down to quality. A poorly made, synthetic latex probably won’t last as long as a well-made foam.

Our Verdict

The WinkBed comes top of our list. It has an exceptional design with seven layers, including motion isolation to make users feel exceptionally comfortable, as well as well-supported. It comes in a number of different firmness options so you can choose which suits you. We’ve rated it 9.9/10.

Next on the list at 9.7/10 is the best value pick, the Brooklyn Aurora Hybrid, it is affordable yet made largely from high-quality foams that could last many, many years without any sagging.

Next on the list of the best mattresses that won’t sag is the Helix Plus, which is designed to be a hefty and supportive mattress, ideal for larger people to use due to the fact it can handle a lot of weight without starting to sag. We’ve rated it 9.6/10.
