To find out how much a memory foam mattress weighs, you’ll need to know what size mattress you have. Naturally, a king-sized bed will weigh more than twice as much as a standard twin bed. The weight of a memory foam mattress depends on several factors in addition to its size.

The overall design of these mattresses makes them heavier than traditional innerspring models. Contrarily, latex foam is comparable to memory foam in terms of density. If you’re still interested after that, keep reading and we’ll get into why it’s important to know how much a mattress weighs.

8 Benefits of a Memory Foam Mattress

#1 Body hugging comfort

In response to your body’s heat and weight, memory foam molds to your shape and becomes more supportive and comfortable. The visco elastic foam conforms to your body shape as soon as you lay down on it. Memory foam’s ability to contour to your body is what sets it different from other mattress materials.

#2 Ideal for all sleeping positions

Because of their adaptive properties, memory foam mattresses are suitable for people who sleep in a wide variety of positions, as their surface contours to their individual weight distribution. If you sleep on your stomach, you won’t have to worry about your spine bending out of alignment, and those who sleep on their backs or sides will feel the same amount of support.

#3 Superior motion absorption

Contemporary memory foam mattresses also have the added benefit of limiting motion transfer. Memory foam is a great option for couples because of its capacity to absorb energy and reduce the impact of movement. One partner can turn over and the other will not be disturbed.

#4 Less back and neck pain

In order to have a restful night’s sleep in a neutral spinal alignment, viscoelastic foam is ideal because it molds to your body’s unique shape. Long-term, this aids in lessening issues associated with persistent neck and back pain.

#5 Hypo-allergenic

A memory foam mattress is an excellent option for allergy sufferers. Polyurethane foam is resistant to dust mites, pet dander, and mold and mildew.

#6 Good pressure relief

Extremely firm mattresses can cause discomfort in the hips, shoulders, knees, and elsewhere. Because memory foam uniformly disperses body weight across the sleep surface, this problem is eliminated.

#7 Sag free and no sinkage

Painful pressure points can develop in the shoulders, hips, and knees on mattresses that are too firm. Memory foam solves this issue by distributing weight evenly over the mattress.

How Much Does A Memory Foam Mattress Weigh And What Affects It?

Memory foam mattresses can range in weight from 40 to 180 pounds. Memory foam mattresses can range in weight from super light to super heavy depending on its size and density. Those are the two to remember if you’re looking for a specific mattress weight.

For what reason does body weight matter when using a memory foam mattress? A fast rule of thumb is that the heavier the bed, the more weight it can support. A heavier mattress is preferable for heavier people or for people who share a bed.


Including regular mattresses, memory foam mattresses can be found in common sizes like twin, queen, and king. Weights outside the range we’ve indicated are possible on the larger or smaller beds offered by some manufacturers. As a result, a memory foam mattress for a twin bed might weigh anywhere from 40 to 60 pounds, while a queen-size mattress normally weighs between 120 and 160 pounds.

Conversely, a king bed, which can weigh anywhere from 130 to 180 pounds, is the heaviest of the three. These are, however, just ballpark figures; the actual weight of your bed will depend on a number of other factors, including the density of the mattress’s core and memory foam layers, as well as the materials used to construct the mattress. Expect something to weigh heavier not just because it’s thicker, but because of its whole size.


Densities of memory foam vary, but remembering what makes something heavier should be simple. Low-density foam mattresses weigh less than their medium- and high-density counterparts. This is due to the fact that increasing density makes the bed heavier and more cumbersome.

How Much Does Every Type of Mattress Weigh? - eachnight

Keep in mind that density is a measure of how many cells per square inch a piece of memory foam has, and that anything with a density of less than 4.0 pounds is considered medium or low density. Once you realize this, it will make sense to you why a memory foam mattress is heavier than an innerspring one.

Pocket coils are the internal mechanism of the latter, making it less dense and more open than memory foam. This is also the reason why a mattress with a pillow top is thicker than one without. However, because latex is used in most models’ construction, certain latex mattresses are heavier than memory foam.

How Much Do A Queen Mattress And Box Spring Weigh?

If we’re talking strictly about the typical weight of a queen-sized mattress, then that number is between 120 and 160 pounds. This assumes a typical queen size mattress of 60 inches by 80 inches. A box spring for a queen bed can range in weight from 60 to 105 pounds.

Remember to consider the type of material your queen-size bed and box spring uses. These are important to remember, especially when you have to ship or move your mattress. To be clear, though, heavier is not better when it comes to mattresses.

What Is The Average Weight Of A Mattress?

It’s important to think about the construction of your queen-size bed and box spring. Always keep these in mind when transporting or relocating your mattress. However, keep in mind that heavy does not always mean a better mattress.

It would be useful to think about your body type or the number of people who will be using it. It is possible for one person weighing 400 pounds or two people weighing 200 pounds to share a bed with a 400-pound weight limit. If you do a lot of traveling, it may be best to have something light and portable, such an air mattress, since portability is a consideration for certain people.

Should I Get A 10-inch Or 12-inch Memory Foam Mattress?

Memory foam mattresses come in a variety of thicknesses, and picking the right one will come down to your individual preferences and how you like to sleep. If you like to sleep on your side, a 12-inch model can provide additional comfort and support. If you prefer not to sink into your mattress or have mobility issues, however, a thinner mattress, such as one that is 10 inches or less in height, will be more convenient.

Memory Foam Mattress Do’s and Don’ts

Putting in the time and energy to maintain your memory foam mattress will pay off in the long run, when your bed continues to offer the ideal combination of softness and support for years to come.

Here are a few easy things you should and should not do to maintain the quality of your mattress:

1. Do Rotate It Regularly

When compared to many other multilayer foam mattresses, our memory foam mattresses are not meant to be flipped over. But to avoid depressions in places of concentrated pressure, we advise you to switch its orientation from head to foot every three months or so.

2. Don’t Get it Wet

Keep liquids from getting on the mattress’s surface if at all possible, as this can cause the foam to break down more quickly. If you tend to have accidents in bed, a mattress protector is a must.

3. Do Use a Suitable Bed Base

The bed’s base should be solid, level, and free of any large gaps. Slats on the base should be between 10 and 15 centimeters broad, with gaps of no more than 5 centimeters. The mattress will wear down faster over time if the gaps are too wide. Use this guide to select the appropriate bed frame for your mattress.

4. Don’t Keep it Near Strong Heat Sources

Memory Foam is a heat-sensitive material, which explains why it conforms so well to each person’s unique body shape. Therefore, it is recommended that you place your memory foam mattress in an area that is not directly in the path of any major sources of heat.

Similarly, the use of electric blankets or hot water bottles on a memory foam mattress is not recommended because the intense heat from these items might compromise the mattress’s performance and even its structure over time.

5. Do Protect it With a Washable Mattress Cover

Most of our mattresses include a cover that can be removed and washed to keep it clean and protect it from spills and stains. Keeping your mattress clean and fresh for longer can be achieved by washing it at 40 degrees.

6. Don’t Make Your Bed!

Finally, we recommend breaching a cardinal rule by not making your bed as soon as you wake up. By doing so, you’ll ensure that your mattress and bedding can breathe and that any moisture produced throughout the night may escape.
