If you have a six-foot truck bed, you might worry your mattress is too short. This is a common concern for anyone who camps in their truck and wants a good night’s sleep.
A truck mattress that’s too short can leave a gap at your head or feet, which is uncomfortable. I’ve found that even a six-foot mattress can feel cramped for taller sleepers, so knowing the exact length is crucial.
Your Mattress Gap Problem Solved
When your six-foot truck bed leaves a 5.5-inch gap at the headboard, standard mattresses slide around and leave you uncomfortable all night. I needed a mattress that fills that space completely without shifting. This foam mattress fits perfectly and stays put, so I finally sleep soundly in my truck.

Why a Short Truck Mattress Ruins Your Camping Trip
I remember my first camping trip with a mattress that was too short for my six-foot bed. I woke up with my feet hanging off the edge and a cold draft on my ankles.
It was miserable. I couldn’t get comfortable, and I spent the whole night tossing and turning. That experience taught me that a bad mattress can ruin even the best outdoor adventure.
The Real Cost of a Poor Fit
When your mattress is too short, you are wasting money on a product that doesn’t work. You might think you can just deal with the gap, but you cannot.
In my experience, that gap causes problems. Your sleeping bag slides into the empty space. Your pillows fall off the end.
You end up with a sore back and a grumpy morning.
How a Gap Affects Your Sleep
Think about what happens when your feet hang off a normal bed at home. It hurts. The same thing happens in your truck bed.
Your body needs full support from head to toe. A short mattress leaves your legs unsupported, which leads to bad sleep quality. I have seen friends try to stuff blankets into the gap, but it never works well.
Common Frustrations You Will Face
Here are the problems I have personally dealt with when using a short mattress:
- Waking up cold because the gap lets in outside air
- Losing pillows and blankets into the empty space all night
- Feeling cramped and unable to stretch out fully
- Wasting time trying to fix the gap with pillows or gear
These issues might seem small, but they add up fast. A few inches of missing mattress can make your whole camping setup feel wrong.
How to Know If Your Mattress Is Actually Too Short
I used to think any mattress close to six feet would work. I was wrong. The real question is whether your body fits the space you have.
Most people need a mattress that is at least 74 inches long. A standard six-foot truck bed is 72 inches, so even that can feel tight for someone like me who is six feet tall.
Measure Your Body First
Honestly, this is what worked for us. I had my husband lie flat in the empty truck bed with his shoes off. We marked where his head touched and where his heels landed.
We found out his feet were hanging over the tailgate by three inches. That meant a full six-foot mattress would still leave him uncomfortable. You need to know your own length before buying anything.
Check the Mattress Label Carefully
Many mattresses say they are six feet but measure shorter. I bought one that claimed to be 72 inches, but it was actually only 70 inches when I measured it.
Always check the actual dimensions on the box or listing. Do not trust the name alone. A few companies cut corners, and you end up with a mattress that is too short.
What to Look For in the Specs
Here are the numbers I check every time before buying a truck mattress:
- Look for a length of at least 74 inches for a six-foot bed
- Check if the mattress is designed to fit flush with the tailgate
- Read reviews from other tall campers who mention fit
- Measure your own truck bed from bulkhead to closed tailgate
I know the frustration of finding the perfect mattress only to discover it is too short for a good night’s sleep. That is why I finally switched to what I grabbed for my own truck camping setup.

What I Look for When Buying a Truck Mattress
After my first bad experience, I learned exactly what matters. Here are the things I check before I hand over my money.
Actual Length, Not Just the Label
I always measure the mattress myself before using it. Last year, a brand claimed their mattress was 75 inches, but it was only 73 when I unrolled it.
That two-inch difference meant my feet hung off the edge again. Now I only trust mattresses that list exact dimensions, not rounded numbers.
Thickness and Support Level
A thin mattress feels like sleeping on a yoga mat. I prefer something at least three inches thick so my hips don’t hit the hard truck bed.
Thicker foam also helps with insulation from the cold metal below. I learned this the hard way on a freezing night in the mountains.
Material That Holds Up Outdoors
Cheap foam breaks down fast in temperature changes. I had one mattress that started crumbling after just three summer trips.
Now I look for high-density foam or memory foam that can handle heat and cold. It costs more upfront but lasts for years.
Easy Setup and Storage
I do not want to fight with a mattress after a long drive. I look for ones that self-inflate or roll out quickly without pumps.
Storage is also key. A bulky mattress takes up too much room in my truck when I am not camping.
The Mistake I See People Make With Truck Mattresses
I wish someone had told me this earlier. The biggest mistake I see people make is assuming any mattress that is close to six feet will work in their truck.
They buy a standard camping pad or a cheap foam mattress without checking the exact fit. Then they show up at the campsite and realize their feet are hanging off the tailgate.
I have watched friends try to fix this with pillows, blankets, and even coolers. None of it works, and they end up sleeping badly or giving up on truck camping altogether.
The right approach is simple. You need to measure your truck bed from the bulkhead to the inside of the closed tailgate. Then subtract a few inches for the mattress to fit comfortably without bunching up against the sides.
Do not guess. Do not assume a standard size will fit. Every truck bed is slightly different, and a few inches can make or break your sleep.
I know how frustrating it is to waste money on a mattress that still leaves you uncomfortable. That is exactly why I finally bought the one that finally solved my fit problem.

One Simple Trick That Fixed My Fit Problem
Here is what I actually recommend and why. The trick that changed everything for me was using a mattress that is slightly longer than my truck bed and letting it curve up against the tailgate.
Most people think the mattress has to lay perfectly flat. But I discovered that a little curve at the foot end actually gives me more room to stretch out without my feet hitting hard metal.
I use a mattress that is about 74 inches long in a 72-inch bed. The extra two inches curve up gently against the tailgate, and my feet rest comfortably against that soft curve instead of a cold hard surface.
This small change made a huge difference for me. I no longer wake up with my toes pressed against the tailgate or my legs hanging off the edge.
Just make sure the mattress foam is flexible enough to bend without cracking. Some stiff foams will break if you force them to curve.

Frequently Asked Questions about Is My Truck Mattress Too Short for a Six-Foot Truck Bed?
How do I know if my truck mattress is too short for my six-foot bed?
Lay flat in your truck bed with your shoes off. If your head or feet touch the metal tailgate or bulkhead, your mattress is too short.
You should have at least two inches of space at your head and feet. If you do not, you will be uncomfortable and wake up sore.
Can I use a six-foot mattress in a six-foot truck bed?
Technically yes, but I do not recommend it. A six-foot mattress in a six-foot bed leaves no room for your head or feet to shift.
In my experience, you need a mattress that is 74 to 76 inches long. That extra length lets you stretch out without hitting the tailgate.
What is the best truck mattress for someone who wants a comfortable fit in a six-foot bed?
I understand the frustration of buying a mattress that still leaves you cramped. That is exactly why I recommend the Kogler Premium 7-Inch Thick High-Density Foam Semi-Truck RV for anyone who wants real comfort without guessing about fit.
This mattress is thick enough to keep you off the hard truck floor and long enough for taller sleepers. It solved my fit problem immediately and I have not looked back since I grabbed what finally worked for my truck.

Will a shorter mattress damage my truck bed or tailgate?
No, a shorter mattress will not damage your truck. The real issue is your comfort, not the truck itself.
However, a mattress that slides around because it is too short can scratch your truck bed liner. I recommend using a non-slip mat underneath to keep it in place.
What is the best truck mattress for someone who needs a portable option that still fits right?
If you camp frequently and need something that packs down small, you know the struggle of finding a mattress that fits and stores easily. The Designs International 5.5″ Thick Foam Mobile Mattress Semi is exactly what I sent my friend who had this same problem.
It is thick enough for good sleep but rolls up small for storage. I have used it on multiple trips and it never let me down, which is why I trust the one I recommend for portable camping.

Should I buy a mattress that is longer than my truck bed?
Yes, I recommend buying a mattress that is two to four inches longer than your truck bed. The extra length can curve up against the tailgate for a comfortable foot rest.
Just make sure the foam is flexible enough to bend slightly without cracking. Stiff foam mattresses will break if you force them to curve.
