What makes this bed stand out is its versatility. You can change the firmness to your liking — just unzip the cover and change the first two layers (Soft and Medium, respectively) until you have your preferred sleeping style.

Now, natural latex has many resourceful uses. 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. What’s more, latex has tiny little pores, which contributes to the mold and dust-mite-resistant properties of the bed, so you can sleep soundly and allergy-free.

  • offers decent edge support and a uniform surface;
  • plush pillow-top for better cradling;

Dreamcloud has surely claimed its place among the top-rated mattresses that don’t sag. Because nothing says ‘anti-sagging’ more than five-layers, a hybrid mattress, and a cloudy-plush feel.

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

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. Plus, 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 pressure relief and contributes to its luxurious look.

One of the last options 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 nice pressure relief.

The mattress packs three layers under the polyester cover, resulting in a soft to medium feel.

Restless sleepers and partners, here’s something to cheer you up: 

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

Highlights

  • temperature-neutral design;
  • optimal firmness level for almost any sleeper;
  • great spinal support thanks to the zoned system;

Who said a good mattress needs a four-figure price tag? Initially made for athletes and people with a demanding lifestyle, who knows the value of solid night’s sleep, the Zoma outperforms some of the more expensive models on the market with ease. 

So, what makes this mattress stand out?

First, there’s a zoned comfort layer that turns the Zoma into a cozy cradle. The zones adjust to your natural curves, with the parts designed for shoulders and legs featuring a triangular pattern that helps evenly distribute your weight.

The dense foam base keeps the construction uniform and absorbs excess motion, which is great if you share a bed with somebody and want to sleep soundly. And the transitional layer is designed to be responsive to your body curves and relieve pressure points in any position you choose.

The whole construction feels temperature-neutral and doesn’t make you sleep hot. The mattress is encased in a soft cover that feels cool to the touch and creates a breathable layer under your body.

To sum up, the Zoma didn’t disappoint in any way. It feels supportive, has a uniform surface, and delivers refreshing sleep. Oh, and it won’t make your credit card faint.

Why Does a Mattress Sag?

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

So, what can contribute to faster sagging?

  • Poor foam quality. All types of foam tend to soften and lose their resilience over time, and with cheaper quality foam, it tends to happen 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 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 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 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. A mattress is designed for sleeping only, so if you often use your laptop, watch TV, or read while sitting on it, the risk of sagging can increase. 
  • Both corners at your feet. Indentations there may appear if you have pets and allow them to sleep with you.

Keep this in mind:

Try utilizing the surface more evenly if you can. You can also try rotating the mattress to promote even weight distribution and prevent premature sagging.

How Will a Saggy Mattress Impact Your Sleep?

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

  • Tossing and turning. When the surface of your mattress loses its uniformity, you will need more time to find a comfortable position to sleep. Also, you may find the positions you once felt relaxed in start causing stiffness and pain in your lower back or neck (1).
  • Insomnia. Spending hours rolling in your bed from side to side can impact your overall sleep quality and duration. This could even lead to anxiety and worry about getting to sleep.
  • Headaches. When your mattress doesn’t provide proper spine alignment and support, your neck and shoulders 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 you guessed it — most US homes have detectable levels of dust mite allergen in their bed. [2] So, if you start noticing you’re getting a sniffly nose or sore and dry eyes when you wake up, your saggy bed could be the one to blame.

Poor quality of sleep caused by all these factors can trigger a whole host of chronic disorders that can contribute to a decline in overall health. So, if you think the root cause of these issues could lie 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

Pay attention, because I’m going to outline the main features that stop a mattress from sagging. The first one is the mattress type.

Today, there are many types of mattresses on the market. Although most of them can be initially uniform and supportive, not all of them stay so for years to come. Let’s dive into 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, the intensity of use, and temperature of the room — may have an impact on how fast your foam mattress loses its resiliency.

Polyurethane Foam

Polyfoam is a cheaper version of memory foam as it requires far less manufacturing resources. It’s also 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 saggy mattresses: 

Polyfoam typically starts losing its shape a lot faster than viscofoam.

Latex

The most long-lasting mattress material nowadays (3), latex, is 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 greater resiliency and more supportive properties.

Hybrid

Hybrid mattresses feature a coil system as the base layer. The other layers are typically foam, latex, or other 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 the important part here.

Innerspring

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

Air Mattress

Most air mattresses tend to lose some air during the night due to temperature fluctuations, so they generally become softer and sag more deeply. But in the case of a sagging air mattress, it’s easily fixed 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 keep your water mattress in good shape, it can offer uniform support, literally forever. 

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

To find a mattress that stands the test of time, without the dreaded saggy bits, you first need to check a few key components. 

Choose the Right Foam Type

Despite some issues with heat retention, high-density foam remains the most durable 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 untimely sagging.

If your budget allows, choose a latex mattress. It may have an unusual feel at first, especially if you’re used to sleeping on foam mattresses, but latex lasts longer than most other mattress materials.

Check Foam Density

To ensure you’re purchasing a quality mattress, it’s important to look at the foam density. Foam density is how much one cubic foot of foam weighs. The higher the number, the denser, and hence, more immune to sagging the foam will be.

Here is the foam density range for each type of foam:

  • polyfoam: 1.7 pounds per cubic foot or higher;
  • memory foam: 3–4.5 pounds per cubic foot for comfort layers, 4.5–5 pounds per cubic foot for base layers;
  • latex: greater than 5 pounds per cubic foot.

Go for the Higher Coil Count and Lower Steel Gauge

If you prefer mattresses with coils, such as hybrids and innerspring, then the main parameters you should check are steel gauge and coil count. Opt for higher coil count as the surface will be more uniform and responsive to your body weight. Choose a lower steel gauge because the coils are thicker and this will have better durability.

Make Sure the Mattress Has Solid Edge Support

Generally speaking, 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 a bed has proper edge support is to check the user reviews.

Wrapping Up

Anti-sagging properties of the mattress are influenced by many factors, with the most important being the quality of the materials and mattress construction. Look for models made of denser foams, natural latex, and those with higher coil count and reinforced perimeter, as these typically last longer than others.

Now, let me introduce my champion mattress. I enjoyed every single night spent sleeping on the Nectar. Despite being rather affordable, the quality of this mattress was built to last. Moreover, it offers adaptive support and impressive pressure relief. The Nectar could work for various types of users, and I’m sure it will help you sleep soundly all night long.

And if you want a bouncier option — which is also environmentally friendly and hypoallergenic, by the way — then go with the Botanical Bliss. Its natural latex is dense and durable, and I’m positive that this mattress will serve you well for years to come.
