Mixsuper Liner Under Seat Storage is a precision-fit 6-piece ABS organizer that tucks under rear seats of 2019–2026 Chevy Silverado and 2020–2026 Silverado/Sierra HD models to keep tools and everyday items sorted and accessible.

When truck cabins fill up, the neglected space beneath rear seats is a simple solution for neat, out-of-the-way storage. This Mixsuper Liner kit delivers a molded organizer, removable inner bin, mesh pocket and mounting hardware engineered for Crew Cab and Double Cab Silverado 1500 and Silverado/Sierra 2500HD–3500HD trucks. Built from impact-resistant ABS, the system resists moisture and daily wear while creating quick-access zones for small gear, safety items, and maintenance tools.

How does this under-seat organizer fit my Silverado or Sierra?

The tray is made to match the exact under-seat footprint of 2019–2026 Chevy Silverado 1500 and GMC Sierra 1500, and 2020–2026 Silverado/Sierra 2500HD and 3500HD Crew Cab or Double Cab models. Installation uses included mounting components so the unit stays secure beneath the seat without altering factory seats.

• Model-specific contours for a flush, low-profile fit
• Designed for Crew Cab and Double Cab seat layouts only
• Includes bolts and brackets for a stable install

What components are included and how do they make organization easier?

The 6-piece set combines multiple storage types so you can separate large items from small essentials. Use the main molded tray for bulkier gear, the removable inner bin for sorting, and the mesh pocket for visible, fast-grab items.

• Main under-seat organizer holds larger tools and supplies
• Detachable inner bin for modular sorting and easy cleaning
• Mesh pocket for fast-access items like gloves, chargers, or maps
• Mounting hardware secures the kit under the seat

What is the build quality and how will it stand up to truck use?

Constructed from high-strength ABS plastic, the Mixsuper Liner resists impacts, scratches, and moisture commonly encountered in trucks. Its rigid structure protects stored items and maintains shape even when loaded with tools or equipment.

• ABS construction for impact and wear resistance
• Water-resistant surface reduces corrosion risk for tools
• Rigid walls prevent deformation under load

How does this affect passenger comfort and cargo access?

Installed beneath the rear seat, the organizer preserves passenger legroom and the main cargo area while adding discreet storage. Because it sits low and flush, it won’t interfere with seat folding or passenger comfort.

• Low-profile design keeps footwell area free
• Does not impede seat movement or folding functions
• Quick access to stored items without opening truck bed or cab storage

Who is this for: The Mixsuper Liner under-seat storage is ideal for Silverado and Sierra owners who want to reclaim wasted space and keep small gear, tools, or personal items tidy and accessible. It suits tradespeople, outdoor enthusiasts, and everyday drivers who need organized storage without sacrificing cabin comfort or altering factory interiors.
