Frequently Asked Questions
How do I stop a trunk mat from sliding with heavy cargo?
Use a mat with a dedicated anti-slip backing (nibs or cleats) and pair it with the vehicle's factory anchor points or aftermarket Velcro/anchor straps. Custom-fit liners that snap to factory clips move least; universal mats often need non-slip strips or adhesive Velcro to secure them under heavy loads.
Are TPE mats safe for car interiors and hot weather?
High-quality TPE is designed to be odorless and heat-resistant, resisting deformation in hot weather. Look for manufacturers who advertise odorless, non-toxic TPE and tested performance in extreme conditions to avoid warping or persistent smells.
Can I trim a universal cargo liner without losing anti-slip performance?
Yes — trimmable liners include marked guides for safe cutting. To maintain anti-slip performance, avoid trimming away sections of the backing that contain nibs or cleats; if trimming is necessary near the edges, add Velcro anchors or adhesive non-slip pads underneath to restore grip.
