Our Reviews of 5 Top-Rated Mattresses That Won’t Sag

Best for High Profile

Dreamcloud

Dreamcloud

Dreamcloud had surely claimed its place among the top-rated mattresses that don’t sag. Because nothing says ‘anti-sagging’ better than this five-layer hybrid mattress with a cloudy-plush feel.

All layers from top to bottom are crafted with comfortable sleep in mind. The combination of materials with different firmness and density levels allows this mattress to contour your body perfectly.

The patented innerspring coil system is the supportive core of the Dreamcloud bed. It enhances the overall breathability of the construction, so the mattress won’t make you sleep hot. Besides, the coils are encased in foam to absorb shock from movement and let you sleep peacefully.

Along with that, the mattress features a cashmere pillow-top that adds some amount of pressure relief and contributes to the luxurious look.

Overall, I loved the Dreamcloud. It may suit people who want a really thick mattress which, aside from giving proper support to their spine, will also look and feel luxurious.

Best for Edge Support

Winkbed

Winkbeds

The next candidate in my review of the best mattresses that don’t sag is the Winkbed. This mattress is available in four firmness options, including the one that is designed for heavy sleepers and couples. And each of them performs great in terms of uniform support of all your body curves.

The surface of the mattress is divided into 5 or 7 zones — depending on the firmness option you choose — and each zone has a slightly different firmness so that your body is supported more effectively.

Another great feature is breathability. Again, depending on the firmness option, the proper airflow is possible due to either the ‘coil-on-coil’ construction or the combo of latex and pocketed springs. Both of these configurations do their job perfectly and keep you cool at night. Aside from that, the coil block also comes with sturdy edges, which makes the Winkbed mattress a good option for people who share a bed with their partner.

Overall, if you need a mattress that won’t sag after years of sleeping, the Winkbed is one of the best options that the market can offer.

Best Eco-Friendly Option

Avocado

And here comes another hybrid option on my list of the best mattresses that don’t sag. The Avocado mattress is the holy grail for those who care about the environment but also want to get a high-end mattress. 

The supportive core of the Avocado is made from upcycled steel coils, so you can imagine its durability. The pocketed coils can also offer you pinpoint contouring and have reduced motion response compared to a solid spring block.

For cushioning and comfort, there’s a layer of Dunlop latex with a medium feel. This is just the right level of firmness to accommodate any sleeper regardless of their sleep position

Finally, I love that the company doesn’t use adhesives and other potentially harmful ways to keep the mattress layers together. Instead, it binds the layers with strong wool threads that go all the way from the bottom to the upper layers and are made into cute wool rosettes on the top of the mattress.

Overall, I had a very refreshing sleep on the Avocado mattress. It can make a perfect fit for those who are trying to live the all-things-gree lifestyle.

Best for Versatility

Botanical Bliss

Botanical Bliss

Time to welcome one more eco-friendly option in my review of the best mattresses that don’t sag. The Botanical Bliss literally stands for its name: it’s made of natural latex, which is produced from  the sap of rubber trees, and has a layer of organic wool, which can make your nights blissfully cool and comfortable.

What makes this bed stand out is its versatility. You can change the firmness to your liking — just unzip the cover and swap the first two layers (they are Soft and Medium, respectively) so that you could adjust your mattress to your sleeping style.

Now, natural latex is awesome for many things. It allows for proper air circulation inside the mattress and offers outstanding durability and edge support, which is crucial if you sleep with a partner. Along with that, latex has tiny pores, and this contributes to great mold and dust-mite-resistant properties of the bed, so you are totally protected during your sleep.

To sum up, the Botanical Bliss is a perfect choice for those who don’t know yet how firm they want their mattress to be. It is adjustable, offers close conforming, and sleeps cool.

Best for Pressure Relief

Puffy

Puffy

And the final candidate in my selection of top-rated mattresses that don’t sag is the Puffy. It’s an all-foam model with a pretty simple construction, which, nevertheless, can offer you superb support and pressure relief.

The mattress packs three layers under the polyester cover, resulting in a soft to medium feel. There’s a gel-infused foam layer for cooler sleep, a foam transition layer for better load distribution and precise contouring, and, finally, a dense foam base for good motion absorption and overall stability of the construction.

Now, restless sleepers and their partners can cheer up at this part: 

The Puffy has incredibly low motion transfer so any movements will be absorbed right from the start. And no, it won’t suck you in like quicksand — you will still be able to easily transition between sleeping positions.

As a sum up, I’d like to say that the Puffy is a reasonably priced mattress with an awesome ability to relieve your pressure points, maintain spine alignment, and last longer than other all-foam models.

Why Does a Mattress Sag?

I hate to break it to you, but no mattress will remain uniform and supportive forever. All the beds eventually start to sag, and the quality of materials, along with how well the mattress is made, is the factor defining how quickly this happens. 

So, what can contribute to faster sagging?

  • Poor foam quality. All types of foam tend to soften and lose resiliency over time, and with cheap ones, it happens even faster. Budget manufacturers use polyurethane or less dense memory foam that has a significantly shorter lifespan and is more prone to forming indentations.
  • Uneven load. If you tend to utilize one particular area of your mattress for sleeping, this may lead to indentations in this area, which will make the surface uneven and reduce its supportive properties.
  • Improper utilization. Placing a foam mattress near the heater or in a room with high humidity can damage the materials and make them more prone to sagging.

And finally, if your mattress is close to hitting the 10-year-old mark, chances are it has already started sagging, even if you don’t see or feel it yet.

Most Common Places for Saggy Spots to Appear

To determine if your mattress is actually saggy and it’s time to replace it, you need to inspect the most common places for indentations to appear.

Here they are:

  • The area right under your body. If you share a bed with your partner, you might actually have two similar indentations on both sides of the mattress. 
  • Edges. Saggy edges often are a result of sitting at the edge of your mattress. In fact, a mattress is designed for sleeping only, so if you often use your laptop, watch TV, or read while sitting on it, a risk of sagging increases. 
  • Both corners at your feet. Indentations there may appear if you have pets and allow them to sleep with you.

Bottom line?

Try utilizing the surface more evenly. You can also try rotating the mattress to promote even weight distribution.

How Will a Saggy Mattress Impact Your Sleep?

How Will a Saggy Mattress Impact Your Sleep

Your body can adapt to nearly anything, including pretty uncomfortable conditions. However, it will still signal you that something’s not right. In the case with a sagging mattress, look out for the following sleep-related signs:

  • Tossing and turning. When the surface of your mattress will lose its uniformity, you will need more time to find a comfortable position to sleep. Also, you may find that the positions which once felt relaxed start causing stiffness and pain in the lower back or neck.
  • Insomnia. Spending hours rolling in your bed from side to side will impact your overall sleep quality and duration. This might even lead to uncontrollable anxiety episodes prior to bedtime.
  • Headaches. When your mattress cannot support proper spine alignment, your shoulders and neck are the ones that suffer the most. Squeezed nerves and blood vessels in these areas can result in tension headaches or migraines.
  • Allergies. Saggy spots make a great place for all the nasty things to build up. That includes organic particles, which are the food for dust mites. And dust mites are the most common bedroom allergen in the US homes. So, if you start noticing troubled breathing or sore and dry eyes upon awakening, your saggy bed could be the one to blame.

Poor quality of sleep caused by all these factors can trigger a host of chronic disorders and worsen your overall health. So, if the root cause of these issues lies inside a saggy mattress, be sure to replace it with a new one as soon as possible.

The Most (And the Least) Sagging Mattress Type

The Most (And the Least) Sagging Mattress Type

Now, I want to outline the main features that make a mattress that doesn’t sag. And the first one I’d like to mention is a mattress type.

Today, there are many types of mattresses on the market. Although they can be initially uniform and supportive at the beginning, not all of them can stay so for years to come. Let me comment on each type in more detail.

Memory Foam

The most common material for mattresses, memory foam is quite unpredictable when it comes to sagging. The density and firmness are determining factors here. But other things — such as mattress foundation, intensity of exploitation, and even temperature in the room — may have an impact on how fast your foam mattress will lose its resiliency.

Polyurethane Foam

Polyfoam is a cheaper analog of memory foam, as it requires fewer resources to be manufactured. It also has an open-cell structure, which allows it to retain a little less heat compared to memory foam. Yet, this structure is the culprit when it comes to durability: 

Polyfoam typically starts losing its shape way faster compared to viscofoam.

Latex

The most long-lasting mattress material nowadays, latex is, basically, the vulcanized sap of rubber trees. Despite having an open-cell structure like polyfoam, latex has smaller cells and thicker cell membranes, which results in great resiliency and supportive properties.

Hybrid

Hybrid mattresses feature a coil system as the base layer, combined with other materials, such as foam, latex, or fibers. Coils are more rigid compared to foam, so they can help keep the surface uniform for a longer time, preventing the upper foam layers from developing indentations. But of course, the quality of the material that the coils are made of is important here.

Innerspring

Traditional innerspring beds have a simple construction. Unlike the hybrids, they only feature 1-2 comfort layers above the spring block. They also are the firmest and pretty long-lasting, but their overall durability, just like with hybrids, depends on the coil count and steel gauge used for making springs.

Air Mattress

Most air mattresses tend to lose some air during the night due to temperature fluctuations, so they become softer and sag more deeply. But it’s the easiest case of sagging, as you can fix it by simply adding more air. Unless the cause of deflating was a puncture. Then you would first have to patch your air mattress properly.

Water Mattress

Waterbeds are great when it comes to cradling because a layer of water encased in vinyl is the most adaptive material ever invented. Also, if you maintain your water mattress in good shape, it will be able to offer uniform support literally forever. Just learn to regulate the water pressure inside.

How to Choose a Mattress That Won’t Sag in the First Years of Use?

How to Choose a Mattress That Won’t Sag in the First Years of Use

Finally, let’s clear out a few important things to look for in a quality mattress that won’t sag so that you could enjoy good sleep without having to replace your bed every couple of years.

Choose the Right Foam Type

Despite some issues with heat retention, high-density foam remains the most durable and sturdy among synthetic materials, compared to polyurethane and infused foams. If your mattress has a base layer made of high-density foam, chances are it will serve you longer without sagging.

“If your budget allows, buy a latex mattress. It may have an unusual feel at first, especially if you’re used to sleeping on foam mattresses, but latex is more long-lasting than any other mattress material.”

Check Foam Density

To make sure you get a quality mattress, you need to look at foam density. This parameter shows how much one cubic foot of foam weighs. Here are the numbers you need to look for in different types of foam:

  • memory foam: more than 4-5 pounds per cubic foot;
  • polyfoam: 1.7 pounds per cubic foot or higher;
  • latex: more than 5 pounds per cubic foot.

The higher the number is, the denser, and hence, more immune to sagging the foam will be.

Go for the Higher Coil Count and Lower Steel Gauge

If you prefer mattresses with coils, such as hybrids and innersprings, then the main parameters you should check are steel gauge and coil count. Opt for higher coil count (this means that the surface will be more uniform and responsive to the weight of your body) and lower steel gauge (this means thicker coils and better durability).

Make Sure the Mattress Has Good Edge Support

Generally, if your mattress has coils, it should also have a reinforced perimeter frame to keep the edges sturdy. The best way to know for sure if the bed has proper edge support is to check user reviews. 

“Choosing a foundation that pairs with your mattress will also allow you to prevent sagging.”

Wrapping Up

A mattress with an anti-sagging design is a great investment in the quality of your sleep and your overall health. You can try one of the models I’ve reviewed above, or find your perfect bed on your own, as you’re equipped with all the information for that. Now, as usual, I’d like to announce my favorites. I totally enjoyed sleeping on the Avocado mattress. Despite its simple construction, this bed remains comfortable and doesn’t provoke any pain even after years of active use. And the combo of long-lasting latex and upcycled coils adds up to its durability. But if you aren’t a fan of a bouncy feel, you should try the Puffy. Its foam construction looks very promising and can support your spine properly aligned for years to come. So, why did you decide to replace your mattress with a non-sagging one? Which model from the list appeals to you the most? Let me know in the comments!
