Yes, two adults can fit comfortably in the back seat of a 2022 CX-5 with a car seat installed, but it will be a tight squeeze for three. The key is the type of car seat and where you place it. For the most comfortable arrangement, install the car seat behind the front passenger seat, which allows the passenger to slide their seat forward slightly to create more legroom for the adult sitting behind the driver.
The 2022 Mazda CX-5 offers 55.2 inches of rear hip room and 39.0 inches of rear legroom. While these numbers are competitive for the compact SUV class, they are best utilized by two passengers. A rear-facing infant seat takes up the most space, often forcing the front passenger seat to be moved forward significantly. A forward-facing convertible seat or a booster seat is less intrusive.
The best configuration is to place the car seat in the outboard seat behind the passenger. This leaves the remaining rear seat space for one adult, who will have adequate, though not generous, legroom. The center rear seat is very narrow and best reserved for short trips only. If you need to regularly transport two adults and a child in a car seat, the CX-5 works, but a midsize three-row SUV like a Hyundai Santa Fe or Kia Sorento would offer a more spacious solution.

We do it all the time. My wife sits in the back with our toddler on longer drives. With the forward-facing seat behind me, she has enough room. It's not limousine-level comfort, but it's perfectly fine for a couple of hours. You just have to be about it—put the taller adult in the front. Trying to fit a third adult back there, even for a quick trip, is a no-go. The middle seat is basically a last-resort spot.

As a taller person, I’m about 6'2", and I’ve been the adult in the back with a car seat. It’s manageable, but you’ll feel the lack of space. My knees were definitely touching the front seatback. The trick is to have the person in front of you be average height or shorter. If two tall adults are trying to sit one behind the other, it gets uncomfortable fast. For a school run or a short errand, it’s fine. For a road trip, I’d volunteer to drive.

Think of it like a puzzle. The CX-5 is a five-seater, but it's really built for four adults and a kid. The car seat one of the rear spots. That leaves one comfortable spot for an adult and one very cramped center spot. If you're just giving a friend a ride home, it works. But if you're planning a family vacation with two grandparents, you'll all be much happier in a larger vehicle. The CX-5 is great for what it is, but it has its limits.

I cross-shopped this exact scenario. The CX-5’s cabin is a bit narrower and more driver-focused than something like a CR-V. The CR-V feels more open in the back. That said, the CX-5 works. The seats are comfortable, which helps. Just know that if you use a bulky rear-facing seat, the passenger in front of it will lose a lot of their legroom. Once you switch to a forward-facing seat, it becomes a non-issue. It’s a short-term space challenge, not a dealbreaker.
