3 Across Installations: Which Car Seats Fit in a Buick Enclave?

The Buick Enclave is one of the Lambda SUVs produced by General Motors, along with its clones the GMC Acadia, Chevrolet Traverse, and now discontinued Saturn Outlook. The Lambda twins are together among the most popular large SUVs (or crossovers, if you will) that you can buy today in the United States. The Enclave competes with other mega SUVs like the Chevrolet Tahoe, GMC Yukon, Toyota Sequoia, and Nissan Armada among families who need–or simply want–something larger than a, say, Honda Pilot or Toyota Highlander, but who aren’t looking to spend as much money as they would in the luxury segment with a Mercedes Benz GL-Class SUV or Audi Q7. They’re cheaper while still offering lots of seating flexibility and room.

In the last few months, I’ve been able to put the Acadia and Traverse through their paces in terms of 3 across car seat installations. However, as is often the case, I still had more seats I wanted to try out. Fortunately, I was able to get a hold of an Enclave this weekend and have been trying out every seat available inside.

Being essentially the same vehicle with very slight interior and exterior trim changes, this list features all of the initial 3 across installations I got to work in the Acadia and Traverse as well as a few new ones I puzzled together in the Enclave. Before looking at the results, though, it’s worth reviewing which kinds of seats are appropriate for kids at different age ranges.

First of all, I suggest rear-facing from day one until you can’t anymore. Rear-facing is the way to go even if it takes you through the preschool years (ideally until 4!). Once you can’t fit your child in a rear-facing seat anymore, forward-face him or her in harnessed convertible or combination seats (ideally until 8!). Once your children outgrow their harnessed seats, it’s best to keep them restrained in high-back boosters until they’re physically and psychologically ready to use adult seat belt systems (which typically happens between 10 and 12). The overriding goal is safety, which comes from using certain kinds of seats at certain times.

With all that out of the way, here’s what I found in a nutshell: like the Traverse and Acadia, the Enclave is a huge SUV, which means you’re going to get most of your potential installations to work if you’re patient and make use of the strategies I suggest below.

The list isn’t complete, but it’s my goal to make it as complete as possible over time. If you find the list helpful when shopping for car seats, you can shop through my Amazon link below. I’ll add more seats as I test them over time.

Tips and Tricks:

The current and only generation of the Buick Enclave is 202 inches long and 79 inches wide, which means you’re going to be able to fit most seats you can think of in 3 across installations with enough effort and a bit of planning. However, there are a few things to be aware of that can make the job significantly easier or more difficult, depending on how you approach them.

First of all, if you have a 3 across setup in the 2nd row, it’s going to be very difficult for anyone to access the 3rd row. This is an issue in the Traverse, it’s an issue in the Acadia, and it’s an issue in the Enclave. You might want to install only a pair of seats in the 2nd row and then another 2 or 3 in the 3rd row if you need to install or use more than 3 car seats on a regular basis.

Second, the biggest challenge in 3 across setups in the 2nd row will be fitting a pair of seats on the driver and center vehicle seats, as there’s a 60/40 split to deal with. Once you overcome that, just about any car seat will fit on the passenger end.

Third, there’s only one top tether anchor available in the 3rd row for forward-facing seats, which means that you won’t want to have more than one forward-facing seat at a time in the 3rd row if at all possible (see here for why tethering forward-facing seats is essential).

Remember, as always, to use seat belt installations instead of LATCH to maximize available space.
