Small dogs and cats rarely settle on a back seat. They slide about on bends, try to climb into the front, or sit in the footwell where they cannot see out and get more anxious by the mile. A booster seat gives them a box of their own, raised to window height and fixed in place.

This one hangs from the headrest on an adjustable strap and is held square by plastic support rods that slot through the sides, so it keeps its shape rather than sagging into the seat. The fabric is waterproof Oxford cloth in black with a white paw print, and the sides have mesh panels so air moves through. A short safety tether inside clips to your pet's harness, and a front pocket holds treats, a lead or poo bags. When you are not using it, the rods slide out and it folds flat.

• Waterproof, scratch-resistant Oxford fabric with mesh side panels
• Plastic support rods keep the sides upright
• Adjustable headrest strap and an inner safety tether
• Front pocket for treats and poo bags
• Folds flat for storage

On size and safety: the maker does not publish exact measurements, so treat this as a seat for small pets, a toy or small breed dog, or a cat, not a medium dog. Always clip the tether to a harness rather than a collar, so a sudden stop pulls across the chest and not the neck. Like most booster seats, it keeps a pet settled and in one place; it is not a crash-tested restraint.
