A sensory crash mat is a crash mat that can be used like a bean bag to increase sensory input and help kids.

{And adults} increase proprioceptive awareness and decrease over-reaction to sensations over time.


I did some research online to find the cheapest way to make a sensory crash mat. Those resources are long gone, but here is what I did that has stood the test of time with not just one boy, but three!

A crash mat needs to be big enough to lay on or fall into and deep enough that no part of the body ever hits the floor.

I started with the cheapest futon cover I could find online. I couldn’t find the one I used, but here are some inexpensive choices in a ton of colors {affiliate link}.

I then went to a local foam company {Yes! There was one down the street I found after some Googling}.

The difficult part was to figure out how many foam blocks the futon cover would need. I did some calculations that I basically needed three levels of blocks – give or take a few – to assure that no part of the body was touching the floor.

I chose a medium density foam that was 6 inches thick and had them cut 80 cubes {6 inches x 6 inches x 6 inches}. Through this process, I identified several places I could do this online, but none of them could come close to meeting the price of my local company plus then I could pick them up and not have them shipped. Foam is not inexpensive. I think my cubes ended up to be in the $150 range.

If you don’t have the ability to make your crash mat, consider getting a giant bean bag chair/sofa.

We put our foam cubes into the futon cover and zipped it closed…a crash mat is born!


I made this crash mat nearly 7 years ago while my son was in Occupational Therapy for Sensory Integration Dysfunction {also known as Sensory Processing Disorder}. At that time, his body was interpreting sensory input in a way that made his reaction to it very unpredictable. I like the term “out-of-sync” because that was really what it looked like from the outside. If you have not read the Out-of-Sync Child by Carol Kranowitz, I highly recommend it {affiliate link}.

A simple hug or hand grab by me would be interpreted by his body {subconsciously!} as an attack which resulted in wild over-reactionary responses. In the early years, this looked to a parent as temper tantrums, but the more I researched it, the more I realized that his body felt under assault and he was in self-preservation mode.

What a hard thing to add to childhood!

Everywhere we went was a battlefield – people bumping into him, kids touching him, play equipment moving back and forth, loud noises, wind…I could go on and on. These things most kids don’t even notice, but for him they were obstacles that had to be overcome before any rational thought could exist.

He was constantly on fight or flight mode.


There are many aspects to our sensory systems, but the one that was most under invasion here was proprioception. I think of proprioception as our body’s knowledge of where we are in space. When all systems are go, we know innately that when we are sitting down:

  1. We feel input from our feet on the floor.
  2. That tells our brain that our knees are bent to around 90 degrees.
  3. This is confirmed by the pressure being felt through the buttocks and thighs from the chair.
  4. Our spine sends in constant positioning cues from the resistance of the back of the chair – we can automatically notice if we are slouching or sitting up straight.

Our neck knows exactly which way to move and bend from all this input to keep our eyes level and head upright.

But what about when any one of those cues goes awry? What if the brain skipped the foot information? Or the back? All of a sudden, the whole body is out of whack…and might even think it is falling.

When I started realizing that my child had the sensation that he was falling all the time, his behavior suddenly started making more sense. He was insecure with his place in the world in a literal way.

To give his body additional clues, he would intentionally bump into things and wear his clothing extremely tight. These things helped him get more information about where he fit into the world.

One of the things that we could do for him at home is provide easy ways for him to get more sensory input. I made a crash mat.


Because additional information in any situation can be helpful when not overwhelming, a crash mat can help a kid make more sense of where his body lay. The soft, but firm foam cubes give more stimulation than a solid surface while varying degrees of pressure are felt throughout. At first, it was something my son could only tolerate for a short period. But it was our go-to bean bag in the TV room and a fun place to relax and read a book. After some time and conditioning to the extra stimulation, his body started reacting positively to it.

It was also a safe place to “crash”. If he wanted to throw himself onto something or jump off a surface, having this below was better than the alternative.

We still use this crash mat as a bean bag alternative. It has held up well and was definitely worth the time and effort. My son has tackled many of his sensory issues in a way that most people would never suspect what he once dealt with.

I love that he now can identify times that he needs a little crash time.


As if parenting wasn’t complicated enough, sensory issues can often manifest as crazy behavior. Once I realized that some of my child’s acting out was because he couldn’t help it, it helped me react in a supportive vs. demanding way. I am not alone in this. In fact, there is a series of posts investigating different kid behaviors in the light of sensory issues hosted at Lemon Lime Adventures.


The wonderful thing about sensory issues is that they don’t require medication or often even extensive medical care – there are things that you can do everyday at home as part of family play to decrease sensitivities and increase body awareness.

The Sensory Fix Tool Kit {affiliate link} was put together by a mom who has first-hand knowledge of what helps along with experts in the sensory field. Not only are there products that will help you decode your child’s behavior, but it is also supported with a year’s worth of printables.

The more we learn from each other about how to help our kids, the better!
