That’s why we scoured for the best tips to prevent futon sagging, to keep you comfortable, and avoid any discomfort.

Why futons sag

Before we know the fix, it is good to understand what causes futons to sag. What are these? 

  • Stuffing used (pure cotton, foam, memory foam)
  • Repeated and prolonged use
  • Sitting or lying down in the same spot
  • Going over the recommended weight limit
  • Frames digging into the futon when used
  • Your sleeping habits

How to keep futons from sagging

Unlike in cartoons where characters pummel the lumps on their beds to fix and get them back to their perfect conditions, in real life, doing that would make it worse.

Here are some great tips you can follow to keep your futons from sagging:

Add support by placing a board under the futon mattress

Most of the time, futon mattresses sag because the slats supporting them are too far apart or thin, which is typical of cheaper metal futon frames.

When there’s not enough support, the weight isn’t spread evenly. This makes the slats press into the futon mattress, which can harm its structure.

You can prevent this by fitting a bunkie board or plywood on the slats before setting down the futon mattress. 

In addition to stopping sagging from the slats, the board will make the futon secure and keep it flat on the frame, so you can sleep comfortably and well.

Use toppers

Using a topper mattress may help reduce sagging and make your futon taller. They offer a more even sleeping area and an extra layer of comfort. 

The toppers are mostly made with foam, wool, down, or feathers with varying thicknesses.

If you are to buy a mattress topper, remember that a thicker futon made with denser material can offer better protection and longer usage.

Flip and rotate the futon mattress

To avoid lumps and fix a sagging futon, flip the mattress over and rotate it from top to bottom at least once a month.

This will even out the futon filling and ensure you do not sit or lie down in the same spot.

If you are a side sleeper, this practical tip is especially beneficial. 

It would allow you to rest the heavier parts of your body (hips and shoulder) on different areas of the futon mattress instead of on the same spots.

Add variation to how you fold the futon

Traditional Japanese and Western-style futons are all designed to be folded and tucked away. 

But if you fold the futon mattress the same way every day for years, it will make it wear out faster, especially in the middle, and it won’t last as long.

To fix this, all you have to do is to refold the futon in a reversed direction. Follow this as part of the futon’s daily maintenance to prevent sagging and keep it in good condition.

Straight from the users

According to Quorans, here are the tips that greatly helped them keep their futons from sagging:

  1. Rotate the Futon Mattress

Rotating your futon mattress helps distribute wear and tear. Aim to do this every three to six months, depending on how often you use it.

This simple step can extend the life of your mattress and keep it comfortable.

  1. Air It Out

If possible, take your futon mattress outside and let it air in the sun for a few hours.

This not only freshens it up but also helps kill any bacteria or mold that might have built up over time. It also safeguards against the presence of bed bugs in your futon.

It’s a natural and effective way to keep your mattress clean and hygienic.

What I recommend

I highly recommend the following tips based on my personal experience as a futon user. Let me share them with you.

  • Use a Mattress Cover

To protect your futon mattress from spills, stains, and dust mites, I suggest using a mattress cover. This protective layer not only safeguards the mattress but also extends its lifespan. 

It’s a small investment that can make a big difference in the long run to avoid a saggy futon sofa bed.

  • Use a board on top of the frame

Frequently, futon mattresses tend to sag, especially when the supporting slats are too far apart or thin, which is often the case with less expensive metal frames.

To prevent this issue, I suggest placing a bunkie board or a piece of plywood on top of the slats before laying down the futon mattress. 

This not only prevents sagging due to the slats but also ensures the futon remains stable and flat on the frame.
