Mixsuper Under Seat Storage Liner for Ford F-Series Crew Cab (2015-2026 F-150, 2017-2025 F-250/F-350/F-450/F-550) – Black
Product description
What it is
The Mixsuper Under Seat Storage is a liner-style organizer designed to sit beneath the rear seat of full-size Ford trucks with 4-door Crew Cab configurations. It’s intended to maximize the space you already have, giving you a dedicated spot for tools, gear, and everyday essentials without occupying precious floor or cargo area.
Who it’s for

If you own a 2015–2026 F-150 SuperCrew Cab or a 2017–2025 F-250/F-350/F-450/F-550 Super Duty, this liner is meant to fit those full-size, four-door models. It’s a practical option for drivers who want to reduce clutter and access stored items more quickly from the cabin rather than digging through the bed or side compartments.
How it helps in daily use


The liner makes the often overlooked space under the rear seat usable. It creates designated compartments that help keep tools, small parts, and other items organized, so you don’t have to rummage around or carry loose items loose under the seat. Quick access from the cab side is a notable convenience when you need something fast during a trip or at a job site.

What stands out on paper
- Designed for full-size 4-door Ford trucks within the specified model years.
- Dimensions approximately 54.7 inches x 12.6 inches x 5.5 inches, which suggests a broad, shallow storage footprint that aims to maximize under-seat space.
- Built for durability with materials described as tough and long-lasting, geared toward daily use and the rigors of a truck environment.
- Black finish fits a wide range of interiors and is unlikely to clash with existing color schemes.
Considerations and limitations

The description notes a general “tough, long-lasting” build but does not specify exact materials or weight capacity. If you need to know whether it can handle very heavy or sharp-edged tools, you may want to confirm the weight rating or test fitment with your typical load. Also, the fit is limited to full-size, four-door models, crew cab configurations outside those years or non-4-door variants aren’t covered.


What it’s not perfect at
If your truck setup uses non-standard rear-seat configurations, or if you require sizable vertical compartments rather than a flatter liner, this option may feel limited. It’s also not a substitute for larger bed storage or dedicated tool chests when you need to transport bulky items frequently.

How to decide if it’s right for you
Conviene tener en cuenta whether you prioritize cabin-accessible storage that doesn’t intrude on floor space. This liner is more about organization and quick access than expanding load capacity. If you primarily keep loose items under the seat and want a cleaner cabin, it could be a good fit. If you frequently haul large gear or need rugged, heavy-duty dividers with explicit weight specs, you might want to compare with alternatives that provide explicit capacity ratings.
Practical use example



Imagine reaching for a roadside tool kit or a small jumper battery without kneeling on the floor or leaning into the cargo area. With items neatly compartmentalized under the seat, you can grab what you need in seconds, not minutes, which helps on longer trips or when you’re coordinating multiple gear pieces.
Quick comparison note
This under-seat liner targets a balance between maximizing unused space and preserving easy access. It sits between empty floor space and a full toolbox, offering a middle-ground approach for everyday organization without committing to larger aftermarket storage solutions.

FAQ snapshot
- Will this liner fit my 2015–2026 F-150 or 2017–2025 Super Duty crew cab? Yes, it’s specified for those models and years, assuming a full-size 4-door configuration.
- Can I store heavy tools? It’s described as durable, but exact weight capacity isn’t listed. Consider light-to-moderate loads and verify fit in your particular setup.
- Is assembly required? The base description implies a ready-to-use liner, with no detailed installation steps provided.
Final decision (Is it worth it?)
It makes sense if you want to reclaim under-seat space with a cleaner, organized interior and quick access from the cab. It may not be the best choice if you need heavy-duty weight ratings or a solution for non-standard cab configurations. If you prioritize a simple, cabin-focused organization approach and own a supported Ford crew cab, this liner is worth considering.
