Verdict

The BAKFlip MX4 Hard Folding Tonneau Cover for the 2021 Ford F150 5'7" bed delivers a solid mix of style, ease of installation, and improved functionality compared to earlier versions. It’s a great choice if you want a secure, sleek cover that offers full bed access without removal and is lighter than previous models. However, if you live in a colder climate or require completely watertight performance under heavy rain, you might want to carefully consider potential minor leaks and latch issues. For those seeking a very rugged option with enhanced locking or cold-weather resilience, exploring other tonneau covers might be worth it, but overall, the MX4 remains a premium, popular pick.

Top pro:
Installs relatively easily with clear instructions and helpful YouTube videos, typically taking about 45 minutes to 1.5 hours.
Top con:
Some users report minor leaks near the tailgate corners and recommend applying additional sealant for better water resistance.
