Size Information
- Size (one size): 50.4 in (width) × 24.2 in (depth). Width runs left‑to‑right across the back seat; depth is front‑to‑back on the seat surface.
- Best for: Covers most truck and SUV rear seats. Spacious for medium and large dogs — comfortable for many breeds such as Beagles, Cocker Spaniels, Bulldogs, and Labradors. Depending on how your dog lies down, this is generally suitable for dogs up to about 70–80 lbs.
- How to check fit (quick): 1) Measure the usable flat area of your rear seat: seat width (side‑to‑side) and seat depth (front‑to‑back). 2) Compare to the extender: it needs roughly 50.4 in width and 24.2 in depth to sit flat. 3) Measure your dog from nose to base of tail (or stand length) to confirm they can lie comfortably within the 24.2 in depth.
- Tip: If your rear seat is narrower than 50.4 in the extender will still work but may sit across the seat cushions; if depth is less than 24.2 in the dog will hang slightly toward the seatback—both are normal and often still comfortable for travel.
