Mattresses have different sizes. It is only expected they have different weights. It is not that simple, though, because other factors influence the weight of your bed apart from the size. Bedroom designs, especially the choice of mattress foundations, can become tricky if mattress weight is not considered. Hence the need to know “how much does a mattress weigh?”.
In this article, factors that affect mattress weight will be discussed to have insight into their mattress weight and, in extension, bedroom designs. However, contrary to popular belief, weight is not the only determinant in knowing quality mattresses.
Key Takeaways:
- Airbeds and Twin-size mattresses tend to be the lightest in weight, while latex and California King mattresses tend to be heaviest.
- Mattress weight affects the foundation and ease of cleaning the most, as some foundations can handle more weight than others, and lighter mattresses are easier to move than heavier ones.

Mattress Weight By Type
Different types of mattresses command different weights. The material with which they were made and the constituents of the mattress influence mattress weights. For instance, what an innerspring queen size mattress weighs will be different from what a latex queen size mattress weighs provided they have the same age.

How Much Does a Mattress Weigh After 10 Years?
A mattress can gain some weight over 10 years, affected by several factors such as an accumulation of body fluids, fungi, dead skin cells, dust mites, and compressed foam. However, all of these factors contribute minorly to your mattress weight and will only affect it by a few pounds.
Old mattresses tend to be heavier because of the accumulation of debris like dead skin cells, skin oils, dirt, and whatnot in the foam(1). Also, after a long time, foams begin to lose their structures. As a result, the foams get compressed permanently, adding weight to the mattress.
Factors such as dust mites can add to an accumulation of weight, as a 2-year pillow can contain as much as 10% extra weight simply due to dust mites and their life cycle (2). A great way to reduce this type of weight gain is by flipping, rotating, and vacuuming down your mattress (3).

Why You Should Consider Mattress Weights
There are some reasons why you should know how much your full size mattress weighs.
Apart from the ease at which you can move a light mattress, other reasons you should be aware of what your mattress weigh are:
- The mattress foundation;
- Cleaning and design of the mattress;
- Setting up a mattress.
The Mattress Foundation
In a situation where you want to replace your king-size mattress, or any other size, how much a king-size bed weighs and what type of king-size mattress you are getting should be foremost on your mind because of the mattress foundation.
Apart from saving you extra expenses on a new foundation, it saves you the stress of sleeping on an unbalanced bed.
Mattress Cleaning and Design
Now and then, we want to change the look, design and even clean our bedrooms and mattresses. It’s no news that lighter mattresses will save you time and energy. Even if your bed is heavy and you know what your mattress weighs, you can prepare for times like this and even get extra hands if necessary.
Setting up a Mattress
Setting up a mattress can be affected by the weight of the mattress in several ways, as a lighter mattress is easier to move than a heavier mattress. If you’re planning on moving, or have issues moving mattresses, consider a lighter mattress to make setting up more accessible. Moving a heavier mattress is possible, but moving it from one place to another may require more assistance.
My Experience With Mattress Weights
In my experience, I have always found weight plays a role, as smaller and lighter mattresses are much easier to move by myself than heavier and larger mattresses. This happens quite frequently when I review mattresses, and I always notice the weight of the mattress changes how the set-up process goes, as well as how supportive and durable the mattress feels overall.
How Does a Mattress's Weight Affect a Mattress?
A mattress's weight can affect the mattress in several ways, such as:
- Its support;
- Its durability.
The Mattress Support
A mattress affects its support (such as a bed frame or foundation) in its weight, as heavier mattresses may cause too much strain on the support system. This can lead to a damaged frame, a sagging mattress, or uneven support over time.
The Mattress Durability
A mattress affects its overall durability as heavier mattresses that lack the internal support to hold heavier materials may lead to damaged integrities and cores over a shorter time.
FAQ
What is the heaviest mattress size?
The heaviest mattress size is the king-sized mattress based on the surface area alone. However, this is not the only determining factor of a mattress weight.
Does a dense mattress mean better quality?
The answer is no. Weight is a byproduct of a good mattress, but the denseness does not indicate better quality. Other variables that affect a mattress's weight, like the materials it's made of, must be considered to determine the mattress's quality.
How do you calculate the weight of a mattress?
The easiest way to calculate the weight of a mattress is to approximate it using the mattress dimensions and material. To calculate, measure and multiply the length, width, and height of the mattress. Then, take that number and divide it by 1728 (the number of cubic inches in a cubic foot.) Find the weight per cubic foot for the material of your particular mattress. Then, multiply the total volume of the mattress by the weight per cubic foot of the material. This will give you the approximate weight of the mattress.
Conclusion
While some factors determine mattress weight, the mattress weight in itself doesn't resolve the quality of the bed. And, in extension, the quality of sleep.
