The instructions were fairly clear when it came to putting this on. However, on our couch I couldn’t figure what to do with the elastic pieces that are supposed to be secured. The cover itself comes in 5 pieces. One for each seat, and 2 for armrests. There is no specific one for each seat, so you can place on whatever one you’d like. 
The material is super soft, as you can see the dogs were already a fan of the soft material.
