How Big Is A Futon Mattress


What Is The Size Of A Futon Mattress?

You have many futon mattresses’ sizes to choose from, but the most common ones are full or double. Because futons mattresses are not what one typically uses as the main bed, you can assume that king and queen futons are not common. It’s also worth noting that there might be some variations with the dimensions you can expect in a futon size for every manufacturer, so you should measure the mattress yourself if you’re buying or making a frame for it. 

Another consideration with futon mattress sizes is their thickness. Some futons are as thick as six inches or more to feel like a regular bed mattress. However, the average thickness in these mattresses ranges from two to four inches. 


Are futons and beds the same size?

In a way, bed and futon sizes are the same. However, you want to check your futon’s specific dimensions when buying accessories like bed frames or sheets. Some users also find futons significantly smaller than a bed they’d like to use for sleeping. 

Nonetheless, there is no reason why one can’t use a futon mattress as their primary bed. You can select the futon with the ideal thickness and construction to suit your needs. The key is to research the perfect setting for your sleeping position as futons might not be a good match in terms of support for some people.


Are There Different Sizes Of Futons?

Much like bunk beds, futon mattresses come in different sizes, including twin and twin XL. The former is 39 inches wide and 75 inches long, while the latter is slightly bigger than 39 by 80 inches. What about a full-size futon mattress?

A full-size futon measures 75 inches long and 54 inches wide, and if the manufacturer offers larger ones like king and queen, they will be 76 by 80 inches and 60 by 80 inches, respectively. As you notice, a standard futon mattress has a good size to double as a couch. Futons are excellent options for households with limited space or as a backup bed for guests since two people can share one. 


What Is The Average Size Of A Futon?

Let’s say that you are shopping for a futon mattress. If you want to assume the dimensions you’ll get, most retailers and stores sold full-sized futons. This size is versatile because you can use it as a bed, but you can also fold it up to be used as a couch. 

If you’re buying a frame for your futon, you can get a similar size to ensure a good fit. For example, a full-sized futon is best for a full futon frame and so on. You can also check if your store offers other sizes as discussed earlier. 


Bi-fold vs tri-fold

You can distinguish futon mattresses into bi-fold and tri-fold. From the name itself, a bi-fold futon will make two separate pieces by folding once, while a tri-fold futon will fold into three pieces by folding twice. Please use this difference when selecting a bed frame. 


What Size Sheets Fit A Futon?

Now that you know how to pick the right bed frame for your futon, you can apply the same principle when buying sheets for it. If you’re using a twin-size futon, then a sheet for a twin mattress would suit it best. Again, you must still check both products’ dimensions to avoid issues with their fitting before you order. 


What is a futon pad?

Another futon accessory that you might stumble upon is a futon pad. Think of it as similar to a mattress topper since you put it on top of the futon and improve its overall feel. The question is, do you need to get a futon pad?

It would be a good investment to use one with your futon because it helps protect the mattress in the long run. Your futon will be less subjected to wear and tear, and you can improve its comfort. However, consider if the added bulk is something you like, or if a traditional cover will suffice for your futon. 


Is Sleeping On A Futon Bad For You?

Sleeping on a futon shouldn’t be bad as long as you select the right one for your sleeping position and body type. Remember that they come in different sizes and materials. However, most futons are quite similar to a giant quilted pillow, so it might not support some users correctly. 



If you are limited in space, you can consider a futon. But how big is a futon mattress? The typical full-size futon is 75 inches long and 54 inches wide. 

However, other sizes come in twin, twin XL, and some manufacturers even have king and queen futons. These mattresses have the same dimensions as beds, but please check the futon yourself to avoid fitting issues.
