The VEVOR WMDY24154 is a back seat extender for dogs. It covers the rear seat and the footwell gap, creating a flat platform and a protective cover so your dog has more room to lie down or stretch out on car trips. It is meant for owners who want to keep seats clean and give a larger dog a stable place to ride.
What a seat extender does
A normal hammock-style cover hangs between the front and rear headrests. An extender adds a firm base that bridges the gap between the rear seat and the front seats, which turns the area into one flat bed. VEVOR says this adds about 40% more space and that the four raised side flaps help keep the dog from slipping off during sudden stops.
Hard bottom and weight capacity
The base uses three detachable honeycomb boards. VEVOR rates the cover at 350 lb, and says this is sturdier than the thin wooden boards used by some others and gives firm support for large dogs. Because the boards are detachable, the cover can be folded for carrying. A rigid base also stops the surface sagging into the footwell, which a soft cover may do.
Seven layers of material
VEVOR describes a seven-layer build, including:
- 600D Oxford fabric, described as scratch-resistant, with a PVC waterproof coating
- Two layers of thick PP cotton filler
- The honeycomb board
- 210D Oxford fabric
- A PVC non-slip mesh underneath
The idea is to keep the seat dry and clean and to protect seats and doors from claws and spills. Oxford fabric is a hard-wearing woven polyester commonly used in bags and covers, and the "D" number (denier) is a rough guide to thread thickness.
Mesh window, pockets and seat belt
A detachable mesh window has slider zippers. VEVOR says it lets you reach your dog during the drive. There are two storage pockets for pet supplies, and a safety belt to secure the dog. As with any pet restraint, follow the manual, and check local rules on how animals should be carried in a vehicle.
Size and fit
The cover is 53 x 24.8 inches (about 135 x 63 cm), with a height of 21.7 inches when set up. VEVOR says it fits most cars and mid-size SUVs, with adjustable straps for fitting. It weighs 7.9 lb (about 3.6 kg). A carrying bag is included, and installation is described as four quick steps.
Who it suits
It suits owners of medium and large dogs who travel regularly by car and want a flat resting surface. It also suits people who often take a muddy or wet dog in the car. Owners of very small dogs may prefer a booster or carrier.
What to check before you buy
- Your rear seat: measure the width and the gap between the seats against 53 x 24.8 inches.
- Headrests: make sure the straps can reach and the front seats can stay where they are.
- Your dog's size: check the dog fits comfortably and has a harness or restraint attachment suited to the safety belt.
- Cleaning: check the manual for cleaning instructions.
- Rear seat use: confirm that the layout still lets people use the seat if needed.
