The quality of this cover is far superior to any other cover we have seen. Rubber bottom prevents slipping. The cover is washable. The installation went quickly. It literally takes seconds. The Velcro on the bottom of the cover allows easy access to all straps and car seat locks for connection. 60/40 zippers expand folding options for large and small seats. The presence of zippers on both sides allows you to use a center console or fit in any car, no matter which side the 60/40 split is on. The case fits easily on our Toyota Avalon or Subaru Outback.
