What Is A Futon? 

So what exactly is a futon? This question is a little bit more complicated to answer than it might seem. The word futon originates in japan. In the Japanese language, futon means bed. This gives us a bit of a hint as to what a futon is.

However, nowadays there are different styles of futons. When some people say the word futon, they might be referring to the traditional Japanese bed, or they might be referring to the western futon. So what’s this difference? 

A traditional Japanese futon is made up of three parts. It is made up of a futon, shikibuton, and a kakebuton. The shikibuton is a mattress, the kakebuton is a comforter, and the futon is a thin cotton pad. 

However, a western-style futon is slightly different. A western-style futon is considered to be a sofa that also functions as a bed. A western-style futon is made up of a futon frame, a futon mattress, and a slipcover. This is the type of futon we are referring to when answering this question. 

Will A Full-Sized Mattress Fit On A Futon Frame? 

Futons convert into beds that are able to sleep people comfortably. So with that in mind, the short answer is yes you are able to fit a full-size mattress on a futon frame. Futon frames are the size of a standard bed. So as long as your mattress is a standard size, then it will fit on the futon frame. 

When it comes to making sure the full-sized mattress fits on your futon frame, you need to check the measurements on your futon frame. A full-sized mattress is 54 inches x 75 inches. The size of a full-sized futon is also 54 inches x 75 inches. This means they are a perfect fit for each other. 

However, you can get different-sized futon frames. Futons can come in sizes single, twin, full, and queen-sized. If your futon frame is a single or twin (38 inches x 75 inches) then your full-sized mattress will be too big for your frame.

If you have a queen-sized futon (60 inches x 80 inches) then your full-size mattress will be too small. That being said your full-sized mattress will fit on a queen-sized futon, it just won’t be flush as it is too small. 

So depending on the size of your futon frame, a full-sized mattress will fit on the futon frame. The question is, should you put a full-sized mattress on a futon frame? 

Should You Put A Full-Sized Mattress On A Futon Frame? 

You might be thinking that since your full-sized mattress fits your futon frame that you can go use it on your futon. Unfortunately, it isn’t that simple. There are many things you need to consider before you decide to use a full-sized mattress on your futon frame. 


If you wish to use the futon frame for both a bed and a sofa then a full-sized regular mattress is not the best choice. Regular full-sized mattresses are made to be sturdy, durable, and flat. That means they were not designed to be folded and bent like futon mattresses are.

They are made from completely different materials. 

Futon mattresses are made from compressed materials put into layers. These materials are often wool, organic cotton, and latex. These materials are bunched together to keep them secure inside the futon mattress. They are firm, but not too firm that they cannot be folded. 

However, regular full-sized mattresses are made to be extremely firm and oftentimes have springs in them. They are thick and heavy, making them almost impossible to fold in half. 

So if you were planning on using the full-sized mattress on the futon frame as a sofa as well as a bed it won’t work. You can put a full-sized mattress on the futon frame if you wish to use the futon as a bed only. Although this depends on the type of frame.

Type of Frame

As we said before, using a full-sized mattress on a futon frame is possible depending on the type of frame. Metal and wood frames should usually work for putting a full-sized mattress on a futon frame, but some frames might not. 

This is because futon frames are not designed to take the weight of a full-sized mattress. Futon mattresses are lighter and so futon frames are made with this in mind. There shouldn’t be too much of an issue when looking at metal futon frames as metal is quite durable.

However, you should always check to see if your futon frame supports your full-sized mattress. 

Frequently Asked Questions

How Can I Check My Futon Frame Supports My Full-Sized Mattress?

Can I Put A Memory Foam Mattress On A Futon Frame? 

The answer to this question is very similar to what we’ve already learned about futon frames. In some instances, you can put a memory foam mattress on a futon frame if you are only using the futon as a bed.

You cannot use the memory foam mattress on the futon frame when it is converted to a sofa. Although, you need to consider what type of memory foam mattress you are putting on the futon cover.

If you are going to use a memory foam mattress topper, then you need to consider the fact that memory foam mattress toppers are only as comfortable as what is supporting them. 


The short and simple answer is yes, you can fit a full-sized mattress on a standard or full-sized futon frame. Although, in most cases you will not be able to use the futon the way it is intended to be used.
