I purchased this about a year ago and used it about 5 times. Unfortunately, the size didn't quite fit my dog. It's well-made, elevates their view, and they ride very calmly in it. I always put a bath towel or something similar down before use, so I don't think there's any dirt, but just in case, I've removed and washed the cover. The bottom cushion is reversible, so I think it's comfortable year-round. Please note that this has been stored at home and inspected by an amateur, so there may be oversights. Please refrain from purchasing if you are concerned. ◇ Prevents your dog from entering the driver's seat while driving. ◇ Prevents your dog from falling under the seat. ◇ Provides peace of mind with a height where you can see your dog. ◇ Also serves as a comfortable place for your dog. ● The cover can be hand-washed after removing the frame. ● Features a reversible cushion with a scratch-resistant fabric side and a boa side. ● Internal size (approx.): 36 x 26 x 21cm ● Weight (approx.): 3.3kg ● Standard pet weight (approx.): Up to 10kg ※ Suitable dog breeds: Papillon, Toy Poodle ● Includes one lead to prevent jumping out. ※ For accident prevention, do not attach to a collar. ※ Cannot be used with headrest-integrated seats.
