Leveling your truck mattress with the included pads is one of the smartest ways to get a great night’s sleep in your truck bed. It stops you from rolling into the wheel well and keeps your sleeping surface flat and comfortable.
I remember the first time I tried it, I thought I just needed to stack the pads under the low spots. In my experience, the real trick is to start with the pads under the mattress itself, not just under the sleeping bag, for the best support.
Fix Your Truck Mattress Gaps
Those included leveling pads never seem to fill the deep gaps between the truck bed and your mattress properly. You end up with hard spots and uneven support that ruins a good night’s sleep. The Designs International 6.5″ Thick Foam Mobile Mattress Semi uses dense, supportive foam that molds perfectly to your truck bed’s contours without sagging.

Why a Level Truck Mattress Matters More Than You Think
I learned this lesson the hard way on a camping trip with my kids. We were so excited to sleep under the stars, but by 2 AM, my youngest had rolled right into the wheel well.
He was frustrated, tired, and crying. That ruined the whole trip for everyone.
The Real Cost of an Uneven Sleeping Surface
When your truck mattress isn’t level, you don’t just feel uncomfortable. You wake up with a stiff neck or a sore back.
In my experience, a bad night in the truck bed can make you want to sell the whole setup. Nobody wants to waste money on a camping trip that ends in misery.
How a Simple Fall Changes Everything
Think about the last time you tried to sleep on a slope. You probably spent the whole night fighting gravity.
For kids, it is even worse. They are lighter, so they slide around more.
Why the Included Pads Are Your Best Friend
Those pads that came with your truck mattress are not just extra fluff. They are designed to fix the exact problem of uneven truck beds.
- They fill the gaps around wheel wells
- They stop you from sliding toward the tailgate
- They create a flat surface for your sleeping bag
In my experience, using them correctly turns a miserable night into a great one. It is the difference between a trip you remember fondly and one you want to forget.
How I Actually Level My Truck Mattress with the Included Pads
Honestly, this took me a few tries to get right. I used to just throw the pads in the truck bed and hope for the best.
That never worked. I would always end up with a lumpy sleeping surface.
Finding the Low Spots First
Before you do anything, lay down in your truck bed without the mattress. Feel around for all the dips and bumps.
I found that the biggest problem spots are usually near the wheel wells and the tailgate. Mark those areas with your hand so you remember where to put the pads.
Stacking the Pads in the Right Order
The included pads are not all the same thickness. I learned to put the thickest pad right on the deepest dip.
Then I layer the thinner pads on top to create a smooth ramp. This stops the mattress from feeling like a seesaw.
Testing Before You Commit
After you place the pads, put your mattress back in and lie down on it. Roll from side to side to see if you still slide.
If you feel any tipping, adjust the pads until everything feels flat. This five-minute test saves me from a night of tossing and turning.
If you are tired of waking up with a sore back or sliding into the wheel well every single night, what finally worked for my family might be exactly what you need.

What I Look for When Buying Replacement Pads for My Truck Mattress
Over the years, I have tried a few different sets of pads. Not all of them work the same way.
The Thickness of the Pads
Thicker pads are not always better. I once bought a set that was too thick and it pushed my mattress up too high.
That made the sleeping surface feel like a mountain. Now I look for pads that are just thick enough to fill the gap without creating a new bump.
How Well They Stay in Place
There is nothing worse than a pad that slides around while you are trying to sleep. I always check if the pads have a non-slip backing.
One time, my pad slid right out from under me in the middle of the night. That taught me to look for something with grip.
The Shape and Size of Each Pad
Not all truck beds are the same size. I look for pads that come in different shapes so I can fit them into tight corners.
Rectangular pads work great for the center, but wedge-shaped ones are better for the wheel wells. Having a mix helps me get a perfect fit every time.
How Easy They Are to Clean
Camping gets dirty. I look for pads that I can wipe down with a damp cloth.
If a pad soaks up mud or rain, it will smell bad by the end of the trip. A waterproof outer layer saves me a lot of hassle.
The Mistake I See People Make With Leveling Pads
I see this all the time at campgrounds. Someone pulls out their truck mattress, tosses the pads in the bed, and just throws the mattress on top.
They think the pads will magically fix everything. That is the biggest mistake you can make.
The real problem is that people put the pads under the wrong part of the mattress. They stack them all in one spot, usually near the tailgate, and leave the wheel well completely empty.
This creates a huge slope that makes you slide toward the cab all night. I learned this the hard way after a miserable night in a national park.
Instead of guessing, you need to lay down in the empty truck bed first. Feel where your body dips and put the pads directly under those spots.
Start with the thickest pad on the deepest dip, then layer thinner pads around it. This creates a smooth, flat surface instead of a lumpy mess.
If you are tired of waking up with a stiff neck because your pads keep sliding around, what I grabbed for my own truck might be exactly what you need.

The One Trick That Changed How I Level My Truck Mattress
Here is the tip I wish I had known from day one. Do not just place the pads under the mattress and call it done.
You need to put your sleeping bag or blanket on top of the mattress and lie down again. The weight of your body will show you exactly where the pads are still off.
I discovered this by accident one rainy night. I had set everything up, but something still felt wrong.
When I lay down with my sleeping bag, I felt a hard ridge right under my hip. I got up, shifted one pad a few inches to the left, and the problem disappeared.
The weight of your body changes how the pads compress. A pad that feels flat under your hand can feel like a rock under your back.
So always do a final test with your full weight on the mattress. It takes two minutes and saves you from a night of tossing and turning.
My Top Picks for Leveling Your Truck Mattress the Right Way
After testing a few different setups, I have two recommendations that I personally trust. These are the ones I would buy again for my own truck.

The Kogler Premium 7-Inch Thick High-Density Foam Semi-Truck RV is the thickest pad I have ever used. I love how it fills the deepest dips around my wheel well without needing extra layers underneath. It is perfect for anyone with a big gap in their truck bed.
The only trade-off is that it takes up more storage space when not in use.

Frequently Asked Questions about How Do I Level My Truck Mattress with the Included Pads?
Do I really need to use the included pads, or can I skip them?
I learned the hard way that skipping the pads is a bad idea. Without them, your mattress will sag into the wheel well and you will slide around all night.
The pads are designed to fill those gaps. In my experience, using them makes the difference between a good night and a miserable one.
How do I know where to place the pads under my mattress?
Start by lying down in your empty truck bed without the mattress. Feel for the deepest dips, usually near the wheel wells and the tailgate.
Place the thickest pad directly under those low spots. Then add thinner pads around it to create a smooth, flat surface for your mattress.
What is the best way to level my truck mattress with the included pads for a pickup with deep wheel wells?
Deep wheel wells are tough because one pad is rarely enough. I have found that stacking two pads on top of each other works best for those big gaps.
If you are tired of fighting those deep wheel wells every night, what I grabbed for my own truck finally solved this problem for me. It fills the space without needing a dozen layers.

Can I use the pads from my old truck mattress on a new one?
Yes, you can usually reuse the pads if they are still in good shape. I have moved my pads between two different truck mattresses without any issues.
Just make sure the pads are clean and not flattened out. Old pads that have lost their shape will not fill the gaps properly.
Which truck mattress leveling pads won’t let me down when I am camping in rough terrain?
Camping on uneven ground makes leveling even more important. You need pads that stay put and do not slide around when you toss and turn.
For rough terrain, I recommend what finally worked for my family because it has a non-slip bottom that grips the truck bed. It stays in place even on steep angles.

How often should I replace the leveling pads?
I replace my pads about once a year if I camp frequently. Over time, the foam compresses and loses its ability to fill gaps.
If you notice your mattress feeling lumpy again, it is probably time for new pads. A fresh set makes a huge difference in comfort.
