How to Set Up Lumbar Support in a Truck Seat

Thirty-one years in a county bus garage will teach you two things about a lower back. It does not forgive a bent-over posture, and it does not care how tough you think you are. I retired in 2021. My back has been stiff and sore since about 2014, worst in the morning and worst again after a long sit. Not the kind of pain that drops you. The kind that makes you plant a hand on the truck door and stand still a second before you climb in.

For years my truck setup was a rolled bath towel wedged behind my hips. It felt fine for about ten minutes, then it slid down and I fished it back up one-handed at highway speed, which is a fine way to meet a guardrail. In March 2025 I swapped the towel for an Everlasting Comfort lumbar pillow and strapped it to the driver's seat of my 2016 F-150. Twenty months later it is still there. The drive to Chattanooga to see my grandkids runs about three hours up I-75, and I stop at Calhoun, roughly two hours in. For a long stretch I got out at that stop and stood beside the truck like a man twice my age, waiting for my back to unlock.

What follows is not a pitch. It is the setup I landed on after a week of moving straps, plus the parts I got wrong first, so you can skip those.

Step 1: Find the spot that actually needs the support

Sit in the driver's seat the way you sit when you are driving, not the way you sit in a waiting room. Both feet forward, hands on the wheel, back resting against the seat back instead of perched on the front edge of the cushion. Then slide a flat hand behind you and find the hollow at the small of your back, right around your belt line and maybe an inch above it. That hollow is where the support goes. Not your shoulder blades. Not the middle of your back.

My first attempt went too high, up around my ribs. It pushed my whole torso forward and I drove the first two miles feeling like I was reading a map laid out on the hood. The second attempt went too low, down behind my hips, which does nothing except make you feel like you are sliding out of the seat at every red light. The Everlasting Comfort pillow is 12.6 inches tall and 13 inches wide, so it covers the whole lower back and stops there. That size is helpful once the height is right, and completely useless until it is.

One thing worth saying plainly, because too much of what you read about this gear will not say it. A support pillow does not fix a back. Mine is better managed than it was in 2014, not fixed, and mornings are still the stiffest part of my day. What the pillow does is keep a truck seat from folding me into a shape my back dislikes for three hours at a stretch. It eases and it supports. That is a smaller claim than the packaging makes, and it is the true one.

Step 2: Set the height with the straps loose, then test it sitting still

Leave the straps loose enough that the pad slides up and down the seat back with a little push. Sit down, press your back into it, and walk the pad up or down until that hollow at your belt line is filled. Then get out, look at where the top edge sits relative to the seam of the seat back, and remember that height. You will want it again after you have moved the thing in and out of the house a few times.

The pad measures 3.5 inches from front to back at the widest, and that thickness changes where your hips end up relative to the pedals. So set the height first, then deal with the seat itself, which is the next step. Do not tune both at once or you will chase your own tail around a parking lot for an hour.

Sit still for a full minute with your back against it before you drive anywhere. What you are checking for is a broad push spread along the whole lower back. If you feel pressure in one small spot, as if a knuckle were parked there, the height is off. Move it an inch and try again. This part is dull, it is not interesting, and it matters more than everything else in this article.

Step 3: Strap it to the seat back, not to yourself

The Everlasting Comfort pillow has dual adjustable straps with extension pieces, and those extension pieces are the reason it fits around a full-size truck seat back instead of only a desk chair. Run both straps around the seat back, one above the other, and pull them snug. Snug means the pad does not shift when you push your back into it. It does not mean cranked down until the foam is dented.

The test I use is simple and takes ten seconds. Get in, sit down hard, then get out and look. If the pad has ridden up two inches, the straps are too loose. If it has left a hard crease across the seat back where it got crushed, they are too tight. Mine has sat at the same height since the spring of 2025 and I have not touched the straps since.

The straps also mean you can move it, which I do more than I expected. Mine lives in the truck, but on days I am not driving I sometimes carry it in and put it behind me in the recliner in the den. It weighs 1.5 pounds, so that is a one-hand job on the way to the kitchen.

It took about a week of moving those straps up and down before the pad sat at my belt line. The first drive after that, I got out at Chattanooga without the shuffle.

Step 4: Re-set the rest of the seat around it

Adding 3.5 inches of foam behind you pushes your hips forward, so the seat setup you had is no longer the seat setup you have. Recline the seat back one notch, no more than that. Move the seat base forward or back until your heel can rest on the floor with your foot on the pedal and a bend left in your knee. Then reset the mirrors, because your eye position moved when your torso did.

Do that adjustment sitting in a parking lot, not rolling down the road, and do it once instead of fiddling every trip. The one thing I would not do is recline so far that the weight comes off the pad. If you are leaning back like you are in front of the television, the pad is decoration.

A note on the wheel. With the pad in, my arms sit a touch closer to it than before. That was fine for me. But if the pad pushes you forward far enough that your arms feel cramped or your chest is close to the wheel, it is too thick for that particular seat, and a slimmer support is the better answer than a bigger one.

Step 5: Give it a week of small moves before you decide

Nobody gets the height right on the first try, and if you judge the thing on a five-minute drive around the block you will probably decide it is uncomfortable and put it behind the seat. It took me about a week of moving it up and down half an inch at a time. The memory foam is firm out of the box. Mine softened a little over the first month, then held, and it has not gone flat in twenty months of daily sitting. Everlasting Comfort uses a removable cover on it, which matters more than you would think after a summer of short sleeves and sunscreen.

What to watch for during that week: whether you stop noticing it, or whether you keep shifting your weight to get away from it. Stopping noticing is the good outcome, and most people who set it up right get there by the end of the week. Keep shifting means the height or the angle is wrong. Move it before you give up on it.

And be honest about what it is for. On a ten-minute run to the hardware store I do not think about it at all, and that is fine. It earns its place on the three-hour drive north and the long haul back. If your longest sit is fifteen minutes, this is not the problem you need to solve.

What Else Helps

The pillow is one piece of a routine, and the rest of the routine is not optional. My physical therapist, Anita, gave me a home stretching program back in 2022 and I still do it. She is also the reason I asked before buying a back brace and a stretcher instead of just ordering them off the internet. If your back pain is new, getting worse, or running down a leg, see a doctor or a physical therapist before you buy anything at all. Gear is not a diagnosis, and a pillow is not one either.

The habit that helps me most has nothing to do with a product. I walk 30 minutes around the neighborhood most mornings. On drive days I get out at Calhoun and take a lap of the truck stop instead of sitting in the cab with a coffee. It adds about eight minutes to the trip, and I get out of the truck at my daughter's place standing straighter than I used to.

At home, a heating pad draped over the arm of the recliner gets used most evenings for twenty minutes, and a massager comes out after yard work. Neither of those comes in the truck. Neither of them is doing the pillow's job, and the pillow is not doing theirs.

The brace and the stretcher are the two I would ask about before buying. Anita told me the brace was fine for heavy days but not for all day, and she told me to start the stretcher on the lowest level and stay there a while. I did both and I am glad I asked. Left to my own judgment I would have worn the brace from breakfast to supper and made things worse.

Who This Suits, and Who Should Skip It

This setup suits anyone who sits for long stretches in a vehicle seat that was built for durability rather than for a back. Truck seats, work vans, older sedans with foam that has given up. It suits anyone who has been using a rolled towel or a folded jacket and is tired of fishing it back into place at highway speed. And it suits a person who wants a small, honest improvement rather than a promise.

It also suits the passenger side more than people expect. My wife Lorraine rides with it on the long trip to Chattanooga when I am not using it, and the Everlasting Comfort pillow straps to her seat back just as well as mine.

Skip it if your pain is new or getting worse, if it travels below the knee, or if you have never had it looked at. Skip it if your cab is tight enough that 3.5 extra inches puts your chest on the wheel. And skip it if what you actually want is to drive nine hours without stopping. Stopping and walking is free and it does more for me than any product I own.
