I know the frustration of crawling into your truck bed at night only to find your feet hanging off the edge. It makes a good night’s sleep feel impossible when your mattress seems built for someone shorter.
Most truck beds are exactly 6.5 feet long, but the actual sleeping space shrinks when you add a bed liner or a tonneau cover. A standard truck mattress often measures just 75 inches, which leaves tall people like us with very little room to stretch out.
My Head Hung Off The Edge
I kept waking up with my shoulders crammed against the truck wall and my head dangling off the mattress edge. Every night was a battle to find a position where my feet didn’t press against the tailgate. The Hoggisleep 7 Inch Semi Truck Mattress gives you the full 80 inches of length so you can stretch out completely without your head or feet hitting metal.
I swapped to the 80-inch Hoggisleep mattress and finally sleep with my head on the pillow instead of the truck floor: Hoggisleep 7 Inch Semi Truck Mattress 32×80 Foam

Why Sleeping on a Too-Short Truck Mattress Ruins Your Rest
I remember the first time I tried sleeping in my truck after a long hike. I woke up at 3 AM with my calves cramping because they had no support.
My feet were pressed against the tailgate, and my head was jammed into the wheel well. It was miserable, and I knew I had wasted money on the wrong setup.
The Real Cost of a Bad Night in Your Truck Bed
When your mattress is too short, you don’t just lose legroom. You lose deep sleep.
In my experience, tossing and turning all night makes the next day feel twice as hard. You end up groggy, sore, and regretting your camping trip before it even starts.
I have seen friends give up on truck camping entirely because they could not get comfortable. That is a shame when a simple fix could have changed everything.
How a Short Mattress Affects Your Body
Lying with your legs bent or your feet hanging off puts pressure on your lower back. I have woken up with a stiff neck more times than I can count.
Your spine needs to stay straight for proper rest. When it curves because of a short mattress, you wake up feeling like you got hit by a truck.
- Your hips sink into gaps, causing lower back pain
- Your shoulders get cramped against the truck walls
- Your legs go numb from poor circulation at night
I learned this the hard way after three bad nights in a row. Now I help others avoid the same mistake.
How to Fix a Truck Mattress That Feels Too Short
After my first few miserable nights, I realized I had to make a change. The standard mattress just was not built for someone my height.
I started looking for solutions that would give me a few extra inches without breaking the bank. Honestly, what worked for us was simpler than I expected.
Adding a Bed Extender or Tailgate Gap Filler
One of the easiest fixes is to fill the gap between your tailgate and the mattress. I used a rolled-up sleeping bag for a while, but it kept slipping.
A proper gap filler keeps your feet supported and stops your mattress from sliding around. In my experience, even adding six inches of space changes everything.
Choosing a Mattress Designed for Tall Sleepers
Not all truck mattresses are the same length. I learned to look for ones that are at least 80 inches long instead of the standard 75.
Some brands make custom sizes that fit specific truck beds perfectly. Measuring your actual sleeping space before you buy is the smartest move you can make.
- Measure from the back of the cab to the closed tailgate
- Subtract a few inches for the wheel wells and bed liner
- Look for mattresses labeled “tall” or “extended length”
You are probably tired of waking up with your feet hanging off the edge and a sore back that ruins your whole day. Honestly, what finally worked for us was switching to a mattress built for taller truck campers.

What I Look for When Buying a Truck Mattress for Tall Sleepers
After making the wrong choice once, I got smart about what actually matters. Here is what I check before I buy anything now.
Actual Sleeping Length, Not Bed Length
Your truck bed might be six and a half feet long, but your sleeping space is shorter. I always measure from the back of the cab to the tailgate, minus the wheel wells.
One friend bought a mattress that fit his bed perfectly, but his feet still hit the tailgate. He forgot to account for the plastic bed liner eating up two inches.
Foam Density and Support
A thin foam mattress might feel fine in the store, but it sags after a few nights. I look for high-density foam that holds its shape under my weight.
Cheap foam also gets soft in hot weather and hard in cold weather. In my experience, a denser foam keeps you comfortable no matter the temperature outside.
Portability and Storage When Not in Use
If you use your truck for work during the week, you need a mattress that stores easily. I prefer ones that fold or roll up without damaging the foam.
Some mattresses come with straps or a carry bag, which makes a huge difference. I learned this after struggling to shove a bulky mattress into my garage every Monday morning.
The Mistake I See People Make With Truck Mattress Length
The biggest mistake I see is people assuming their truck bed length equals their sleeping space. They buy a 75-inch mattress for a 78-inch bed and wonder why their feet hang off.
I made this exact error myself. I measured my bed, bought a mattress that matched, and still ended up cramped because the wheel wells and tailgate gap ate up my legroom.
Ignoring the Wheel Wells and Tailgate Curve
Most truck beds have wheel wells that stick into the sleeping area. Your mattress cannot sit flush against the cab if those bumps get in the way.
I once helped a friend who lost four inches of usable space because his mattress hit the wheel wells. He had to slide it forward, which pushed his feet right off the edge.
Not Testing the Setup Before a Trip
Another common mistake is waiting until you are at the campsite to find out your mattress is too short. I always lay my mattress in the truck bed and lie down on it before I leave home.
This takes five minutes and saves you from a miserable night. In my experience, a quick test at home reveals problems you would never notice just looking at measurements.
You are tired of waking up with your calves cramping and your back aching because your feet have nowhere to go. That is exactly why I finally switched to a mattress that actually fits my height.

One Simple Trick That Gave Me Six Extra Inches of Legroom
Here is the tip I wish someone had told me years ago: sleep diagonally across your truck bed. I know it sounds odd, but it works better than you think.
By angling your body from one corner to the opposite corner, you gain several inches of usable length. I tried this during a rainy camping trip when I was desperate, and it completely saved my night.
The trick works best if you have a wide truck bed, but even in a standard size, it helps. I now angle my mattress pad slightly so I naturally settle into that diagonal position.
How to Make the Diagonal Sleep Position Work
I place my pillow in the upper left corner of the bed and let my feet point toward the lower right corner. This simple shift gives my legs the extra room they need to stretch out fully.
You might need to rearrange your gear or storage bins to make room. In my experience, the extra comfort is worth rearranging a few items before bed.
One caveat: this works best if you sleep alone. If you share the truck bed with a partner, you will both need to angle in opposite directions or find a longer mattress instead.
My Top Picks for Tall Sleepers Who Need More Truck Bed Room
After testing a few options and talking to other tall campers, I found two mattresses that actually solve the length problem. Here is exactly what I would buy if I were you.
Mytee Products 5.5 Inch RV Mattress 30×78 Luxury Foam — Perfect for Standard Beds
The Mytee Products 5.5 Inch RV Mattress 30×78 Luxury Foam gives you a full 78 inches of sleeping length, which is three inches more than most truck mattresses. I love that the high-density foam does not sag after a few months of regular use. This mattress is ideal for someone with a standard six-and-a-half-foot bed who just needs those extra inches.
The only trade-off is the 30-inch width, which might feel snug if you are used to sprawling out.
- Width: 30" | Length: 78" | Thickness: 5.5"
- Color: Gray | Material: Polyurethane Foam | Pinstripe Cover
- FMVSS302 Grade Cover | Double Sided Quilted Cover
Designs International 5.5″ Thick Foam Mobile Mattress Semi — Best for Custom Fit
The Designs International 5.5″ Thick Foam Mobile Mattress Semi is my pick for anyone with a unique truck bed shape or wheel well layout. I appreciate that the foam is firm enough to support my back but still soft enough for side sleeping. This one works great if you need to cut or trim it slightly to fit around bumps in your bed.
Just know that it does not come with a cover, so you will need to buy one separately.

- Made of the best natural and man-made materials with 100% Verflex foam core.
- Hypoallergenic and environmentally safe.
Conclusion
The real fix for a too-short truck mattress is knowing your actual sleeping space, not just your bed length.
Grab a tape measure and lie down in your truck bed right now — that five-minute test will tell you exactly what size mattress you need to finally sleep comfortably.
Frequently Asked Questions about Why Does My Truck Mattress Feel Too Short for My Height?
How do I measure my truck bed correctly for a mattress?
Start by measuring from the back wall of the cab to the inside of your closed tailgate. Do not include the tailgate itself if it folds down.
Then subtract two to three inches for wheel wells and any bed liner thickness. This gives you your true sleeping length, not just the bed length.
Can I use a regular twin mattress in my truck bed?
A regular twin mattress is 75 inches long, which is the same as most standard truck mattresses. It might fit, but you will have the same length problem if you are tall.
I have tried this myself, and the twin mattress left my feet hanging off just like a truck mattress did. You are better off finding something longer than 75 inches.
What is the best truck mattress for someone over six feet tall who needs more legroom?
If you are over six feet tall, you need a mattress that is at least 78 inches long to keep your feet supported. I found that the longer options make a huge difference for my own comfort at night.
That is exactly why I switched to a mattress built for taller sleepers instead of settling for a standard size. It gave me the extra inches I needed to finally stretch out fully.

Will a mattress topper help if my truck mattress feels too short?
A mattress topper adds comfort but does not fix a length problem. It will not give you extra inches for your feet to rest on.
I tried using a topper hoping it would help, but my legs still hung off the edge. You need a longer mattress, not a thicker one, to solve this issue.
Which truck mattress won’t let me down when I am camping in cold weather?
Cold weather makes cheap foam get hard and uncomfortable, which is the last thing you want after a long day outside. I look for high-density foam that stays soft even when temperatures drop.
After testing a few options, what I grabbed for my own cold-weather trips held up perfectly through freezing nights. It kept its shape and support no matter how cold it got outside.

Can I cut a longer mattress to fit around my wheel wells?
Yes, you can cut some foam mattresses to fit around wheel wells or other bumps in your truck bed. I have done this with a sharp electric knife, and it worked well.
Just make sure the mattress has solid foam inside, not a gel or memory foam layer that might crumble. Cutting a high-density foam mattress is easy and gives you a custom fit.
