A quilted back seat cover with stiff panels that bridge the footwell, so your dog gets a firm, level platform across the back seat ("hard bottom", 4Knines' term). XL is 60 in wide, for full-size trucks and large SUVs (per 4Knines). Not for captain's chairs.

  • Door panels that zip open
  • Seat belt openings
  • Waterproof bottom layer (per 4Knines; seams and zippers aren't watertight)
  • Hose or wipe it; machine-wash gently without the panels

Help your dog in and out: it's a higher step. Not made for chewing; don't use with heated seats on. Also in Regular (54 in).
