Futon Frame, Mattress, and Sheet Sizes

What Is A Futon Frame, Mattress?

It is a piece of furniture with sleeper and sofa functions. In essence, it is a mattress that has been set up on a frame. The structure can be collapsed into a bed-like shape or folded up into a couch or sofa. The popularity of futons is a result of their adaptability.

Because you don't need a bed and a couch, they are ideal for tiny rooms. They may easily be converted into a bed when necessary, making them ideal for guest rooms as well. Now that you know what a futon is, let’s check out some futon mattress dimensions. Just the most common sizes though.

Twin 39” X 75”

A modest spare bedroom or small apartment would be the perfect place for a twin-size futon. That's because it is appropriate for little adults or kids.

I'd advise using a space that is at least 7 feet by 10 feet in size. This will ensure comfortable use with a twin-size futon mattress.

Full/Double 54” X 75”

For two smaller kids, a full futon mattress, also known as a double, would be ideal. The majority of people would imagine a futon of this size if you asked them to describe one. It is the most frequently used size for use in medium to large spare rooms.

To ensure comfortable use while using a full-size futon mattress, I'd advise a room size of 10 feet by 12 feet.

Queen 60” X 80”

Do you have a spacious spare room or open-concept living area? A queen-size futon might be the right choice for you! 2 average-sized people can comfortably sleep on a queen-sized futon mattress.

I would advise a required room size of 10 feet by 14 feet to ensure comfort. This will be whilst using queen-size futon mattresses.

King 76” X 80”

The largest width size offered for a futon mattress is a king. It can easily accommodate two people of just about any size. A spacious master bedroom or open-concept living area is the ideal place for a king futon. Usually, only tri-fold futon frames are able to accommodate the size of a king and larger.

I'd advise at least a room size of 12 feet by 14 feet. This is to help guarantee pleasant use when utilizing a king futon mattress.

California King 72” X 84”

The total surface area of a California king futon mattress is equal to that of a king. However, it is thinner and longer.

For tall people who prefer the extra length but don't require the width of a conventional king, it is ideal.

I'd advise a room of at least 14 feet by 12 feet. To encourage comfortable use when using a California king futon mattress.

What To Check For When Purchasing A Futon Mattress?

As with everything we purchase, research needs to be done. In order for you to make the right choice when purchasing, be on the lookout for these important factors.


For futons, I would suggest memory foam because it offers the added support. That is something smaller frames wouldn't be able to.

You can also consider a:

  • Innerspring
  • Cold foam
  • Hybrid mattress

Hybrid mattresses would be your best bet if you prefer something firmer. That’s because it contains both coils and foam layers. Next are the classic Japanese futons. These are known as shikibutons. Shikibutons are made with cotton padding and generally have numerous layers.


The thickness of a futon mattress can range from 2 inches to 8 inches. If you would like your futon to bend into a sofa, anything over 8 inches thick will be tough to bend. If you are keeping it traditional, Japanese futons fall on the thinner side. Also take note that if you intend on placing your futon on a base, it is not unusual to feel the frame's bars. This is an easy fix, a slightly thicker futon mattress topper will do the trick.


Although Japanese futons were designed to be on the floor, western futons weren’t. So firmness is a question of preference. However, if you plan on getting a Western futon, I would advise getting a firm one. This just allows both sleepers and sitters to enjoy it with plenty of support.

Styles Of Futon Mattress

Japanese and Western styles are the 2 primary subcategories of futon mattresses.

Japanese Futon Mattresses

Shikibutons, or traditional Japanese futons, differ slightly from regular futons. But because of the variations in design, they are a very adaptable product. Japanese traditional futon mattresses are rectangular. They are slim, nd have foldable cushions that are usually stuffed with cotton. The cushions on these futon mattresses offer users padded support and comfort.

When it's bedtime, people in Japan place these futons on top of a tatami which is a straw mat. They then cover themselves with a blanket and a thin pillow. When they wake up, their futons are placed outside the sun. This is to clean and rid it of bacteria.

Western Futon Mattresses

In contrast to their Japanese cousins, western-style futons often resemble short sofa beds. They frequently have western mattress-size dimensions and can't be folded. In addition, they are put up and placed on a slatted base. This eliminates the need to move them frequently to let them air out. Usually, they are constructed of cotton, foam, or an innerspring core. They provide a more comfortable resting experience. This makes them well-liked in the west.

How To Convert A Futon From Sitting To Sleeping Mode?

There are several procedures for changing it from seating to sleeping mode and back. This will depend on the sort of futon you have.

  • You must take out the seat and rear pillows from bi-fold and tri-fold futons. This needs to be done prior to folding the structure in half or smaller
  • It can take a few more steps to convert a loveseat futon into a compact bed
  • The mattress and bedding can be added once the frame has been folded
  • You must perform the opposite action to return the futon to its sitting position

Alternatives To Futons

There are several futon substitutes that have comparable functionality, including:

Sofa beds: A bed is concealed inside of a sofa bed. Like a futon, they can switch from a sitting to a sleeping position.

Day Beds: Day beds, also known as trundle beds. They are primarily made for sleeping but can also double as daytime seats. Typically, they contain a trundle bed underneath that can be pushed out. This is to provide more sleeping space.

Murphy Beds: When not in use, Murphy beds are made to be folded up and stowed away. They cost more but take up less room than a futon.

What Weight Capacity Does A Futon Have?

The weight capacity for queen futons ranges from 200 to 300 pounds. This, however, depends on the brand and design of your futon.

It's recommended to get a futon with a weight limit of at least 400 pounds if you intend to use it as a bed for two people. If you're unsure, always consult the manufacturer's instructions.

Is Sleeping On A Futon Safe?

Yes, organic futons pass all testing requirements. Using one while sleeping is completely safe. Some individuals even say that they are more comfortable than standard beds. However, it's always better to start by talking to your doctor if you have any health issues.

To lessen off-gassing, be cautious when selecting a futon frame and mattress. Especially if it is made of non-toxic materials.

How Can I Prevent My Futon Mattress From Moving?

The most common reason for a sliding futon mattress is an uneven frame. You can correct this by leveling the futon by adjusting the legs.As an alternative, you can get specialized grip tape or clips to prevent the mattress from moving.
