So You Want to Put Car Seats in Your 2020 GMC Sierra 1500 ...

Car seats have met their match when it comes to full-size pickup trucks. Case in point: The 2020 GMC Sierra 1500 crew cab swallowed each of our bulky car seats — rear-facing infant seat, high-back booster seat and a convertible installed in rear- and forward-facing modes. The GMC Sierra 1500 also fit our three car seats across its backseat with ease.

The Sierra's cavernous rear seat easily handled our rear-facing infant and convertible seats. And because there's so much legroom, there was no need to move the front passenger seat forward to accommodate either of these large car seats. The booster seat fit well in the Sierra, but the seat belt buckle is floppy, making it difficult for kids to buckle up independently.

Installing the forward-facing convertible seat went well, but parents new to pickup trucks or convertible car seats might be flummoxed by the tether anchor setup. Once the convertible seat is installed in the rear seat, you'll need to run the tether strap through the tether loop directly behind the rear seat's head restraint, and then take the tether hook and connect it to the tether anchor next to the car seat. If you're confused, make sure to consult the owner's manual
