The bolster is the whole reason this seat works. Firm foam runs around the rim, so a dog sits down inside a shallow bucket instead of sliding around on a flat pad, and there is something solid to lean against when the car turns. In our testing the difference showed up within a few miles: the dogs that fidgeted on flatter seats settled into this one and stayed down.
The installation is the other half of it. The seat belt threads underneath the removable cushion, so the belt is out of the way and nobody is sitting on a buckle, and the seat comes with two tethers — one for the harness, one spare. At 3.2 pounds it lifts out with one hand, which matters when you are swapping it between cars or clearing the seat for a grocery run. The front dips down low enough that a dog walks in rather than being lifted over the side.
Sizing is where to pay attention. The large is a 22-by-20-inch footprint rated to 35 pounds, roomy enough for two small dogs to lie down together, and the contoured back is shaped to sit against either a front or a back seat. The cover and cushion come out and go through the machine, and there is a side pocket for wipes — which sounds trivial until the first muddy ride.
The trade-off is space. At 22 by 20 inches it takes over most of one passenger seat, so if the back seat already carries two kids or another car seat, measure before you commit. A household with one ten-pound dog and a tight back seat can look at the folding PETSFIT instead. For everyone else, this is the seat we keep coming back to.
Bottom line: We recommend the K&H to almost everyone: the firm bolster keeps a dog settled in a way the softer seats here do not, and it moves between cars in seconds.
