This one is great, easy to put up/take out, fully washable, quality fabric, and affordable! There are no side covers for the doors, downside of the taco, works just fine for us. It does sag a little in the middle/center console area, so the big dog can sneak a paw over when not buckled, but is easily fixed with a little tightening. Easy velcro slots for accessing seatbelts, and works with booster seats. Have had it for 2 years, going strong.
