Mixsuper Liner Under Seat Storage is a custom-fit 6-piece ABS organizer kit that tucks under rear seats to create secure, tidy storage for 2019–2026 Chevy Silverado and 2020–2026 Silverado/Sierra 2500HD/3500HD Crew and Double Cabs.

Make the most of the unused space beneath your truck's rear seats. This engineered underseat system provides a low-profile bin, a removable inner tray, a mesh pocket, and mounting hardware so tools, gear, and everyday items stay organized, protected from shifting, and easy to reach without sacrificing passenger room.

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

The kit is molded to match the floor contours of 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2020–2026 Silverado/Sierra 2500HD/3500HD — for Crew Cab and Double Cab models only. Each piece aligns with factory mounting points for a secure, factory-like installation.

• Vehicle-specific fit for listed model years and cab types.
• Includes mounting components for a snug, rattle-free install.
• Low-profile design preserves legroom and seat travel.

What components are included and how do they help keep things organized?

The 6-piece kit contains the main underseat organizer, a detachable inner storage bin for grouping items, a mesh pocket for small essentials, and necessary mounting hardware. Together they separate tools, safety gear, and everyday items so nothing slides around during drives.

• Main ABS underseat bin for larger items and long tools.
• Removable inner bin for sorting small parts or electronics.
• Mesh pocket for quick-access items like chargers or gloves.
• All mounting pieces included to secure the assembly.

What materials and durability features should I expect?

The organizer is injection-molded from high-strength ABS plastic for impact resistance and long-term wear. The material handles regular loading and unloading, resists moisture and common cabin conditions, and is simple to wipe clean.

• Sturdy ABS construction resists dents and abrasion.
• Moisture-tolerant surface for easy maintenance and wipe-downs.
• Removable inner bin simplifies cleaning and inspections.

How will this affect daily use and access to stored items?

The low-profile layout keeps stored items hidden yet within quick reach, delivering organized access without opening the bed or hauling gear out of the cab. The mesh pocket provides instant visibility for frequently used items while the inner bin can be lifted for loading or transport.

• Hidden storage reduces cabin clutter and improves safety.
• Quick-access mesh pocket for small essentials.
• Removable inner tray allows fast sorting and carrying to the jobsite.
