The best under-seat storage boxes
The rear footwell is the only dry, lockable, out-of-sight space on a work truck that costs nothing to use. These are the four boxes worth putting in it.
Our top pick: the Rough Country Under-Seat Storage — Silverado / Sierra (2019-2022).

Rough Country Under-Seat Storage — Silverado / Sierra (2019-2022)
Rough Country's under-seat box for the 2019-2022 Silverado and the 2500/3500 HD trucks.
Tap any row for the full write-up. Prices come straight from Amazon and are never typed in by hand.
If you want one lockable box in the cab rather than a bin on the back seat, the Rough Country under-seat box for a 2019-2022 Silverado or Sierra is the one we would fit first: it is a moulded box made for a specific cab rather than a universal tub, it publishes a model number you can check against your truck, and it is the only pick here published as lockable. This page ranks four ways to use the rear footwell, from that box down to a seat-back organizer for the truck nobody makes a box for.
Under-seat storage is the one upgrade on this whole site that adds space without taking any. Everything else on a work truck trades: a tool box eats bed floor, a drawer system raises the load height, a rack adds wind noise. The void under a crew cab's rear bench is already there, it is already dry, it is already behind locked doors, and on most trucks it is holding nothing but a jack bag and a winter's worth of grit.
Fit a hard box if your truck has one made for it and you want to lock something away out of sight. Fit a seat-back organizer instead if your problem is paperwork, meters and small tools rather than theft. The mistake is buying a universal tub for a cab it was not shaped for — it will not sit flat, and the seat will not fold onto it.
How we ranked these
Four criteria, scored 0-10 and published on every card. The weighting here is unusual because fitment matters more in this category than anywhere else on the site: a box that is close to right is a box that stops the rear seat folding, which is worse than no box at all.
Fitment honesty. Whether the maker names the truck, the cab style and the years, or hides behind “fits most trucks”. The published fitment line is reproduced on every card below, exactly as the maker states it.
Security. Whether the box locks at all. Most do not, and a box inside a locked cab already sits behind one barrier — but there is a real difference between out of sight and actually secured.
Usable shape. Deep and narrow beats wide and shallow under a seat, because the cushion limits height, not width. A box that uses the full footwell depth holds a cordless kit; one that does not holds gloves.
Seat function after fitting. The test nobody runs before buying: does the rear bench still fold up or down the way it did? On a crew cab that fold is how you carry anything tall indoors, and losing it is a daily annoyance.

Good to know. Model and year specific. Buy the generic box if your truck is not on the list.

Cut for the 2015-2026 F-150 SuperCrew and Crew Cab footwell, and listed with a detachable bin and a mesh net inside it. Correct fit is the whole value in an under-seat box — a generic tub rocks on the floor ribs and rattles for the life of the truck — and the lift-out bin is what makes a box this shape usable rather than a pit.

Why we picked it

+Sits flat on the floor ribs
Good to know. SuperCrew and Crew Cab only; the SuperCab footwell is a different shape. The maker publishes no material, no dimensions and no lock, so if you need a box that is published as lockable, the Rough Country box is the one on this site that states it.

A hard box that fills the void under a crew-cab rear seat. That space is completely wasted in every crew cab and it is the single best place in the truck for recovery straps, a tool roll and a first aid kit.

Good to know. It reduces the usable rear footwell. If a passenger regularly rides back there with boots on, they will notice.

Duck canvas organizer that hangs off a seat back. Simple, and it solves the specific problem of a passenger seat buried in paperwork, tape measures and a hard hat.

Good to know. Hanging weight on a seat back means the whole thing swings on a corner. Load it with paper, not with sockets.

Read that table and the pattern is obvious: this is a category where makers publish fitment and almost nothing else. That is survivable, because fitment is the only specification that can make the purchase fail outright. It does mean you should measure the footwell before you order anything, which takes a tape measure and thirty seconds.
Measure the footwell first — two numbers
Both measurements are taken with the rear seat in its normal down position, because that is the position the box has to live under.
Depth, front to back, from the back of the front seat rail to the base of the rear seat cushion at its lowest point. This is the number that decides whether a box swallows a cordless kit case or only loose hand tools.
Height under the cushion lip, at the shallowest point rather than the deepest. Footwells are not flat and the cushion is not level; a box sized to the deepest point will foul the seat at the front edge and stop it folding.
If the numbers come out tighter than the box you were looking at, the honest answer is a seat-back organizer instead. That is not a consolation prize — on a truck where two people share the cab daily it is often the better purchase, because nothing has to come out of the way before somebody sits down.
What belongs in a cab box, and what does not
The cab is dry, climate-controlled and lockable, which makes it the right home for exactly the things a bed box is wrong for.
Put in it: meters, lasers, levels, battery packs and chargers, a first-aid kit, documentation, anything with electronics in it, and the one cordless tool you need most often.
Keep out of it: anything wet, anything oily, anything that smells of fuel, and anything heavy enough to become a projectile. A heavy unsecured box in a footwell is a hazard in a collision, and that is not a theoretical concern.
Leave in the bed: everything dirty. The point of cab storage is that it is the clean, dry end of the truck — fill it with jobsite grime and you have simply moved the mess inside.
They are not competitors, and anybody telling you to choose has misunderstood both. A drawer system solves reach and volume in the bed; an under-seat box solves having one dry lockable place for the expensive, small things. The under-seat box costs a fraction of what a drawer system costs and is the better first purchase on a truck that has neither.
If the bed is the real problem — climbing over the tailgate to reach the bulkhead, tools loose on the floor — that is the category to spend in instead. Drawer systems ranks the bed-side answers, and cab organizers covers the console and seat-back end of the same problem.
Where we would start, in one sentence
Measure the footwell, buy the hard box made for your exact cab if one exists, and if it does not, buy a seat-back organizer and stop looking — a universal tub wedged under a seat it was not shaped for is the one outcome here that nobody is happy with.
Questions people actually ask
What is the best under-seat storage box for a truck?
The one made for your exact cab. On a 2019-2022 Silverado or Sierra that is the Rough Country box, which publishes a model number and is listed as lockable; on a 2015-2026 F-150 SuperCrew it is the DiffCar box. If no maker lists your cab, a seat-back organizer is a better buy than a universal tub.
Do under-seat truck storage boxes lock?
Some do and most do not. Of the picks here only the Rough Country box is published as lockable. Remember the box sits inside a locked cab already, so the lock is a second barrier rather than the only one — but it is the difference between out of sight and actually secured.
Will an under-seat box stop the rear seat folding?
A correctly sized one will not. A box sized to the deepest part of the footwell often does, because the cushion is not level and the box fouls the front edge of the fold. Measure the height at the shallowest point under the cushion lip, not the deepest.
Is under-seat storage worth it on a work truck?
It is the cheapest storage upgrade on the truck, because the space already exists and you lose nothing by using it. It will not replace a bed box or a drawer system — it is where the meters, chargers and lasers live, not where the hand tools go.
Can I fit an under-seat box in a regular or extended cab?
Usually not a hard box, because the footwell behind a regular cab seat is a fraction of a crew cab's and most listings are written for crew and SuperCrew cabs. A seat-back organizer or a console organizer is the realistic answer there. Cab organizers covers both.
