The average weight of a mattress is between 50 and 150 pounds. Mattress weight depends on the size, thickness, and materials. An innerspring Twin mattress weighs around 40 pounds while a King latex mattress weighs up to 180 pounds or even more. Consumers almost never complain about their mattresses being lightweight, but you will come across complaints about heavy mattresses just because they’re too difficult to move around. Not every quality mattress is heavy, but almost every heavy mattress means that it is made up of a lot of material and has good quality and durability.
Average Mattress Weight
Let’s take the Queen size as a common mattress size since it’s the most popular one among shoppers. A Queen mattress can weigh 70 pounds if it’s an innerspring mattress and up to 90 pounds if it’s made of memory foam. A Queen hybrid can weigh over 100 pounds whereas a latex Queen size mattress can weigh around 140 pounds or more.
The average weight varies greatly and this is because of three main factors – mattress size, mattress type, and mattress thickness.
Factors That Play a Role in Mattress Weight
Mattress Sizes
Mattress size determines the space within which a manufacturer can construct a mattress. If it’s a small one, less material will fit and it will therefore be a light mattress. However, don’t forget that material type also plays a role. Below is a table showing the weight of different mattress sizes. Depending on the particular materials in a mattress, it may weigh a few pounds more or less than what’s in the table. Still, this should give you a good idea of how much a mattress weighs.
- Twin mattresses are the smallest of the mattress sizes, just 38 by 75 inches and they weigh around 40 to 45 pounds. The twin bed frame is typically a choice for a child or a teen.
- Twin XL mattresses are pretty much the same but 5 inches longer. This adds a couple of pounds so a Twin XL weighs around 43 to 48 pounds. Twin XL beds are good for single sleepers who don’t need a lot of room to spread around.
- Full mattresses weigh between 50 and 60 pounds. They are as long as a Twin but wider. With the size of 56 by 75 inches, this bed is ideal for a couple of kids or even a couple of petite adults. Some people can’t decide between a Full and a Queen bed, but we have a guide for that.
- Queen-size mattress weight is a lot higher. With 60 by 80 inches, it can be as heavy as 160 pounds. The lowest average weight can be around 120 pounds. Queen mattresses are the most popular mattresses as they offer just enough space for most people and are not as luxurious and expensive as larger mattresses.
- King mattresses weigh anywhere from 130 to 180 pounds. It’s 76 inches wide and 80 inches long. This super-wide mattress may be a good solution for a large couple or those who frequently share the bed with their small kids.
- California King mattresses have the same area as King mattresses and they would normally weigh the same. They are narrower and longer – 72 inches by 84 inches and as such make the perfect mattress for a really tall couple or a couple who likes to have a dog sleeping at their feet in a way that allows plenty of sleeping space for everyone.
Mattress Types
Construction plays a big role in mattress weight and this list gives you a quick look into which materials are light and which are heavy.
Airbeds and air mattresses are the lightest mattresses because no material can beat the weight of air. Some of them can go on your bed frame but bear in mind that airbeds are much less durable than other mattresses.
Innerspring mattresses are the least heavy of the traditional mattress types. They have a coil system and a thin top of foam or other soft material. Those with a higher number and thickness of coils are heavier. Still, the air pockets between those coils make them pretty lightweight.
Memory foam mattresses typically weigh more than the innerspring ones because their entire body is full of material. On top of that, memory foam mattresses are typically made up of several foam layers, some of which are quite dense and heavy.
Hybrid mattresses typically contain steel coils and a thick comfort layer. The complex construction makes some hybrids very heavy.
Latex mattresses weigh even more because this natural type of foam is denser and heavier than artificial foam. Latex beds are the heaviest – a King size latex mattress can weigh about 200 pounds.
Mattress Thickness
Don’t forget about the mattress thickness – a high-profile mattress weighs more than a thin low-profile one. Beds that are around 13 inches tall use up much more materials and therefore weigh more. A difference between a high and a low-profile mattress can be measured in tens of pounds.
Some sleepers prefer tall beds but if mattress weight is your concern, you shouldn’t ignore mattress thickness.
Why Do People Prefer Light Mattresses?
The main reason behind wanting to buy a lightweight mattress is usually with the person who has to deal with moving it around. If you’re not the one changing the sheets, rotating the mattress, or moving the entire bed to clean, you probably won’t really care about the mattress weight. After all, there are some really good, relatively thin and lightweight mattresses out there.
Should I Buy a Heavy Mattress?
The main pro of a heavy mattress is that it’s very likely of high quality and durability. Heavier mattresses tend to be firmer, but don’t take this as an absolute rule. There are soft memory foam mattresses out there that are also heavy.
Downsides include difficulty moving the mattress around and real trouble for those who have to ship the mattress by themselves.
In general, don’t go for the weight itself – look for high-quality mattresses or at least the best compromise.
FAQs
The heaviest mattress would be a Cali King or King size bed made of latex and with a high profile, because both Kings fall into the category of oversized mattresses and latex foam is the heaviest mattress material. So the actual weight of such a mattress can go up to over 220 lbs!
A mattress can weigh between 20 and 80 kilograms, depending on the size. A Twin can be about 18-22 kilograms, while a King or a Cali King mattress typically weighs between 60 and 80 kilograms.
Tempur-Pedic mattresses are known to be on the heavy side. This is because they are made of many dense foam layers. They actually take pride in their super-dense foam a cube of which weighs a little over 5.3 pounds. Normally, you’d find a memory foam mattress with a density of around 3-4 pounds per cubic foot.
You probably don’t want a mattress so heavy that you can’t move it by yourself or lift it when you’re changing sheets.
Here’s a really bad idea: browsing for bed frames and mattresses separately without checking the mattress weight and frame weight limit. If you need a new mattress that would fit into a bed frame from a different manufacturer, you should check weights and weight limits. This way you’ll be sure that your bed frame isn’t too weak and that it won’t break under the weight of yourself and your heavy mattress.
Finally, shoppers who want a high-quality mattress shouldn’t focus on weight too much. They should research what mattress types there are and how to know which one’s right for them.
There is a weight limit to every mattress regardless of the mattress type or size. Mattresses usually hold between 230 and 500 pounds of weight.
If your body weight is below 200 lbs. or your and your partner’s combined weight doesn’t exceed 230 lbs, you don’t have to worry about the weight limit. Otherwise, be sure to know how much your bed can hold.
If you need to know the exact weight limit of your particular mattress right now, skip the guesswork and visit the website of your manufacturer. There you’ll find the weight limit of your model.
