How Much Does A Mattress Weigh

Getting a new mattress should be a simple task, but it often feels like anything but. There are hundreds of mattresses to choose from, all from different brands, and they come in different sizes, thicknesses, and weights.

For seniors, part of getting the right mattress is finding the right weight. Mattresses are heavy and can be hard to move, so this is important!

How much does a mattress weigh? And how should you go about choosing the right mattress size and dimension for your needs? Read this brief article to find out!

How Much Does a Queen Mattress Weigh?

Queen-size mattresses are quite likely the most common mattress size in the world. They’re large enough for two people to feel comfortable but not so large that they take up all the floor space in a small bedroom. The standard dimensions of a queen mattress are 60 inches wide by 80 inches long. This size means they’re on the heavier side, but certainly not the heaviest.

More important than the length or width of the mattress is the thickness and materials. Innerspring mattresses tend to be the lightest because they have lots of air pockets and negative space. On the heavy side are memory foam and latex mattresses which are essentially thick slabs of dense foam.

A thin, lightweight queen mattress like the Linenspa 8-Inch Medium-Firm weighs just under 60 pounds, while an ultra-thick memory foam option like the Novaform Comfort Grande weighs about 100 pounds. This falls right in line with the average range, but some mattresses can be lighter (as light as 40 pounds) while others much heavier (140+ pounds)!

How Much Does a King-Size Mattress Weigh?

King-Size mattresses, as you’d expect, are the heaviest of the heavy. It’s very hard to find them in a thickness less than 8 inches; most are between 10 and 16. King mattresses are built to be ultra-luxurious and provide the most comfortable sleep possible. This means that the manufacturers likely aren’t too worried about weight when designing king mattresses.

The dimensions of a King mattress are similar to the Queen but much wider. They are 76 inches wide and 80 inches long- 16 inches wider than any other mattress type! They’re perfect for people who like (or need) a lot of room to spread out on their bed. But, this extra width combined with the fact that most king mattresses are on the thick side makes them the heaviest and hardest to move.

On the lighter side, you can find a King size mattress like the Linenspa 6-Inch Mattress (one of the few King mattresses that is less than 8 inches thick)- which weighs 57.7 pounds. That’s abnormal for a King mattress; an average model weighs about 100 pounds. The heaviest King mattresses, like the Stearns & Foster Lux Estate, weigh close to 200 pounds!

How Much Does a Twin Mattress Weigh?

Twin mattresses are, of course, the lightest. They’re usually quite thin, in addition to their smaller dimensions (75 inches long and 36 inches wide). Twin mattresses are, for the most part, very simple and emphasize comfort and efficiency over luxury.

Lightweight innerspring twin mattresses like this one from Classic Brands weigh just 35 pounds. Heavier models, such as this one from Dynasty Mattress are still lighter than most Queen and King mattresses, weighing only 55 pounds.

Twin mattresses are the best way to save space in a small bedroom- but only if you know you’ll be sleeping alone. If you’re with a spouse or partner, a twin mattress simply won’t cut it.

How Thick Should a Mattress Be?

Mattresses, of course, come in all shapes and sizes. There are mattresses that are as little as 6 inches thick; others, though, are 16 inches or more! On top of that, the price you pay for a mattress is largely dependent on how thick it is. So, what is the best thickness for a mattress? What’s too little, and what’s too much?

The average thickness of a mattress is 10-14 inches; the vast majority of popular, high-quality mattresses are in that range. A 6 or 8-inch mattress, while affordable, isn’t always a good idea. Especially if you’re a heavier person, it’s very easy to sink to the bottom of a 6-inch mattress and feel like you’re sleeping on a rock.

When a mattress is too thick, it can be hard to get into/out of because it’s too high up. More than that, ultra-thick mattresses are very expensive, and the extra inches are rarely necessary. If you want to get good value from your mattress purchase, it’s wise to stick within that 10-14 inches range!

Mattress Types and Thickness

Certain mattress types work better with different thicknesses. Memory foam mattresses work the best when they’re between 10 and 12 inches thick. This makes them thick enough to support the user without sinking and thin enough that it doesn’t feel like being trapped in the foam.

The thickness of an innerspring mattress has a great effect on its overall comfort. The thicker it is, the softer it is and therefore more comfortable for most people.

The best innerspring mattresses are often 14-16 inches thick, and some might even be 20 inches thick! If you’re a firm sleeper, though, you’ll want to err on the thinner side so that you get the firm sleeping surface you desire.

How to Know Which Mattress Size You Should Buy For Your Needs

Bedroom Space

If you’ve recently moved or it’s been a long time since you evaluated your bedroom, you may want to consider how changing the size of your bed could maximize the space. For people with small to medium-sized bedrooms, a King bed will be way too large; it will take up too much space and leave the room feeling cramped and cluttered.

If, on the other hand, have a very large bedroom, a Full or Queen bed might seem too small. The goal is to create a nice balance between floor space and bed space. If you think your bedroom could use an update, consider changing mattress sizes to fit the space!

Sleeping Surface Space

If you’ve been using a bed fit for two people for many years but no longer need to (or if you’ve been using a single-person bed that now feels too small), it’s time to make a change. Getting the right bed size helps you feel more comfortable and secure as you sleep. Too big a bed and you can feel “lost” on the sleeping surface.

If your mattress is too small, you (as well as your spouse or partner) will constantly feel as though you’re going to fall off the edge. Before buying a new mattress, take a look at your current sleeping space and ask yourself whether or not you have too much space, not enough, or just the right amount!

Mattress Size and Price

Getting a new mattress is always expensive; downgrading to a smaller size can save you lots of money. In fact, downgrading from a King to a Queen or from a Queen to a Full bed is a great way to knock up to $400 off the price of the mattress! This means you can get a much nicer mattress and pay far less for the smaller size.

Just like mattress thickness, the size of the mattress you choose has a big impact on the price you pay. If you don’t actually need a King bed and you want to save some money, it is always worth it to downgrade! Of course, if you simply want the luxurious and large sleeping surface of a King mattress, you should go for it- but be prepared to pay!

Tips for Buying the Best Mattress for Your Needs

Comfort is King

It may sound silly to say, but the way a mattress feels is actually the number one indicator that it will be a good choice and beneficial to your health. Whether it’s firm or extra-soft, 6 inches thick or 16, all you want to do is find the mattress that works best for you. A mattress- even a nice one- that doesn’t fit the body is a leading contributor to poor sleep quality.

When you are sleeping, your body needs to be comfortable enough to decompress, enter the deepest stages of the sleep cycle, and recover from the day’s aches and pains. If it doesn’t fit, you’ll be tossing and turning all night. If the mattress you test out feels amazing the first time you lay in it, the chances are high that it’s the one for you! Don’t second-guess your body’s natural response!

Temperature Regulation

This is something that many people don’t think about until it’s too late. If the mattress you choose does a poor job of regulating body heat, you are going to feel hot and uncomfortable at night no matter what you do.

There are many mattresses that feature excellent temperature regulation- keeping you cool but not cold- and many options are very affordable. If you think that temperature regulation will be important to you, don’t forget to confirm that the mattress you’re considering will be up to the task!


Most mattresses are by no means light- they typically weigh between 40 and 150 pounds. If you’re concerned about lifting and moving a mattress yourself, there are many high-quality mattress options that are still relatively light. More importantly, getting the right mattress size for your needs is a great way to make sure you don’t get one that is too heavy, too thick, or too large!
