WeatherTech
WeatherTech's 30 by roughly 18 inch mesh panel blocks the gap between front seats without a rigid frame and can accommodate seats that are not aligned. Headrest clips and lower straps connect to suitable seat-frame points, while a storage pocket adds utility. It is a soft deterrent, not a chew-proof barrier or collision restraint.

Kurgo
Kurgo reinforces its nylon and mesh panel with horizontal, vertical, and metal support rods, giving more shape than a basic fabric deterrent. The 27 by 22 inch panel fits fixed or removable headrests and includes a cup holder, but Kurgo excludes two-door cars and minivans. The brand's own travel guidance distinguishes containment from restraint, so pair it with an appropriate harness or secured crate.


4Knines
4Knines is explicit about what this approximately 19 by 22 inch quilted mesh panel is: a deterrent, not a chew-proof safety barrier. Quick-release clips and adjustable straps make it simple to remove for washing, while the official page directs owners toward a harness or travel crate for a safe ride. It suits calm dogs that only need a visual boundary, not determined climbers or chewers.


Walky Guard
Walky Guard clamps to adjustable rear headrest posts and publishes a useful 34-56 inch width and 12-18 inch height range. Its powder-coated steel frame weighs about 5 pounds and can leave the parcel shelf in place. The brand expressly excludes fixed headrests, a middle seat-belt box, and small dogs that may pass between bars.

PetSafe
PetSafe's tension frame is useful when headrest-mounted hardware will not work, spanning 32-49 inches wide and 33-57 inches high between a stable cargo floor and suitable headliner contact points. Rubber caps and a storage pouch improve usability, but the installation must never press against glass, a moving sunroof, or an unsuitable headliner. It is not a dog restraint.

Pawple by Arf Pets
Pawple supplies broad steel-mesh coverage at a much lower price than premium exact-fit or anchored barriers. The 35.5 inch center panel expands to roughly 59.5 inches with two side panels and mounts without tools to rear headrests. Measure the actual headrest span and lower and side gaps, especially for small dogs, and use a separate collision restraint.
