Why Do You Need a Folding Tonneau Cover?

You’ve likely seen folding bed covers on several pickup trucks, but what’s the point? Folding tonneau covers are handy additions to every pickup, especially for those who rarely use the bed for hauling tools, building supplies, and oversized cargo. 

For items prone to water damage, like luggage, furniture, and groceries, a folding tonneau cover offers exceptional moisture and weather resistance, keeping your valuables clean and dry. Folding tonneau covers also offer security against thieves, protecting your valuable cargo while you leave your pickup unattended.

Most folding tonneau covers also offer simple, no-drill installation and ultra-low-profile designs, sitting practically flush with your pickup’s bed rails for maximum aesthetic impact.

Styles of Folding Tonneau Covers

Folding tonneau covers are offered in Hard-Folding and Soft-Folding variations. Most of our truck bed covers are tri-fold, featuring three panels, though some options come in quad-fold configurations. Check out our top styles below. 

Soft-Folding

Soft-folding tonneau covers are constructed from a large sheet of marine-grade vinyl or canvas material stretched over an alloy frame. Utilizing a series of hinges, these bed covers allow you to fold the cover towards the bulkhead for up to ⅔ bed access. However, removal and installation are quick and easy if you need access to the entire bed. Soft-folding tonneau covers typically offer a tool-free installation in under 30 minutes.

Hard-Folding

For added security, consider a hard-folding tonneau cover. Instead of using a vinyl or canvas-based material as the primary cover, hard-folding bed covers employ hinged, sturdy aluminum or composite panels for the main structure. These bed covers are also quick and easy to install. However, many offer full bed access and can be folded against the rear window, such as the BAKFlip MX4 and UnderCover Flex.
