2nd Backrest Mat for 2017-2023 GMC Acadia - All-Weather TPE Protection

In this review of the 2nd Backrest Mat for 2017-2023 GMC Acadia, the bottom line is simple: it is best for Acadia owners who want tough, all-weather protection with a tailored fit. The reviewer found the mat's custom design for Denali, SLE, SLT and AT4 trims and the thick TPE construction to be the single biggest reason to buy, since it stops dirt, salt and moisture from reaching the rear seatbacks while remaining easy to clean and durable for year-round use.

Key Features

• Upgraded Attachment: Retains hook-and-loop fasteners and adds a custom buckle and lanyard to reduce slippage and keep the mat in place.
• All-Weather Protection: Waterproof and non-slip surface shields the backrest from dirt, sand, rain and snow and is simple to wipe clean.
• Easy Maintenance: The material is easy to rinse or wipe down and does not trap smells, making it practical for frequent use.

Who It's For

This mat suits GMC Acadia owners who carry kids, pets, gear or outdoor equipment and need a robust, form-fitting barrier for the rear seatbacks.
