These seat covers are easy to install. Unlike many seat covers, they don't have straps and elastic bands that you have to tie under the seat. Instead, they only have two short straps (more for the long back seat cover). They come with a sturdy round plastic buckle. Put a strap on a buckle. Then insert the buckle through the car seat, between the back of the seat and the bottom of the seat back. Do the same for the other strap. They hold the cover in place. The non-slip silicone backing also ensures the covers stay in place.
The plush car seat covers are fully washable. You can wash them under running water or rinse them or throw them in the washing machine. The plush fabric will not be damaged. Once you've washed them and they're dry, shake them well or blow them with a hairdryer. This will restore the fluffiness of the plush material. If you don't use them for a long time, you can simply roll them up for storage.
