Ford sold a lot of F-150s in 2020 and 2021, and plenty of them are now second-owner trucks with 70,000 to 130,000 miles on the clock. The seats are usually the first thing a new owner notices. Not because anything is broken, but because the driver’s side has a shape the passenger side does not. A flattened outer bolster, a shiny patch of leather, a lumbar knob that clicks and does nothing. Whether you are covering a good interior or trying to stop the decline, it helps to know how these two model years differ and where the wear actually starts.
The Two Model Years Share Almost Nothing
The 2020 truck is the last of the thirteenth generation. The 2021 is the first of the fourteenth, and the seat was redesigned along with the cab. The 2021 cushion is wider at the shoulders, the frame changed, and the plastic side trim that holds the power switches has a different profile. Ford also added Max Recline seats to Platinum and Limited trucks for 2021, which fold almost flat for resting at a job site.
That history matters when you order anything that has to fit. Patterns cut for a 2020 cushion pull tight across a 2021 seat base and leave the switch panel half buried. My honest read: the 2021 seat is the better long-term piece, mostly because the foam is denser and the bolsters are shaped to hold up under a heavier driver.
Bolsters Take the Brunt
Every entry and exit drags across the driver’s outboard bolster. Denim rivets, keys, a phone in a back pocket, and 200 pounds of body weight going over the same six inches of foam four times a day. By 90,000 miles the bolster is usually flat, and the cover material has a sheen that will not come out with any cleaner.
Press the bolster with your thumb and count how long the foam takes to spring back. Slow recovery means the foam is tired, and a cover will hide that without fixing it. An upholstery shop can add a layer of firm foam for a few hundred dollars, which is worth doing on a truck you plan to keep.
Lumbar: Manual Knob or Power Motor
An XLT from either year generally has a two-way manual lumbar knob on the side of the seat back. Lariat and above get ten-way power with a power lumbar bladder. The manual version almost never fails. The power version has a small motor and a plastic bladder that can leak or seize, and the symptom is a switch that moves the seat but does nothing for your lower back.
Test it before you buy covers, not after. Run the lumbar all the way in and all the way out and listen for the motor straining. If you add a thick foam-backed cover, expect less lumbar travel, because the cover eats an inch of the space the bladder was designed to fill.
The Switch Panel Sits Where Dirt Lands
Power seat switches live on the outboard side of the cushion, which is exactly where road salt, coffee, sand, and dog hair collect. The switches are not sealed. A dead fore and aft function on a six-year-old truck is often a sticky switch rather than a failed motor, and a blast of electrical contact cleaner fixes more of them than owners expect.
Any cover you fit has to leave that panel fully exposed. Look for a cutout shaped to the trim, not a universal slit. On the outboard side of the seat back there is also an airbag seam on some trims, and covering it is not negotiable.
What Fit Actually Means
Fit is where most of these purchases go wrong. Listings for 2020 f150 seat covers usually state which cab, trim, and seat type the pattern was cut for, and that detail matters more than the material. A SuperCrew with captain’s chairs and a SuperCab with a 40/20/40 bench are different seats, and a pattern that ignores the difference will wrinkle at the console edge within a week.
Even within one generation, the outline changes. Shoppers comparing 2021 f150 seat covers with the older set will find a different cushion shape, because the fourteenth-generation base and the Max Recline backrest changed it again. Ask about headrest posts, the fold-flat rear latch, and whether the cover has a strap or a tuck flap, since a flap that is too thick will not seat under the plastic trim.
The Rear Seat Ages Differently
Rear cushions get less body weight and more cargo. Tool bags, a car seat base, a dog, lumber with a sharp corner. The fold-flat latch on a SuperCrew is the part that fails first, and a cover that blocks the latch makes the seat useless for hauling. Check the latch before you cover anything, then lubricate it with a dry silicone spray rather than grease, which collects dust.
Car seat bases leave dents in the foam that never fully recover, and the indent shows through a cover within a month. If you haul kids daily, put a thin pad under the seat and keep the cover’s tuck flap clear of the anchor points. The rear headrests also rattle on some trucks, and a strap that crosses the posts will quiet them.
- Confirm the cab and seat type (bench, captain’s chair, 40/20/40) before ordering anything.
- Check that the power switch panel and any airbag seam stay fully uncovered.
- Press the driver’s bolster and time how slowly the foam recovers.
- Run the lumbar and all power functions through their full travel first.
- Clean and condition the seats before installation, never after.
Keeping the Seat Under the Cover
Vacuum the seams and treat leather with a conditioner before anything goes on. Grit trapped under a cover acts like sandpaper on the dye, and slick silicone dressings make the cover slide and bunch at the bolster. Re-tension the straps after two weeks, once the material has warmed up and stretched. A soft brush gets grit out of the seam faster than a vacuum nozzle, and it costs almost nothing.
Then leave it alone. Wash cloth covers twice a year with mild soap, wipe leather covers with a damp microfiber, and fix spills the same day. The seat underneath will still look like a 2020 or 2021 truck seat when the cover comes off, which is the whole point.
