I purchased these for the first time three years ago after seeing them on my aunt's couch. I get the Deluxe pet sofa and loveseat. Along with the armless loveseat. I have larger furniture that is very boxy. I also have two large dogs 75lbs and three boys 8, 12, and 16. These covers have protected my furniture without question. Nothing gets through to the cushions. Including slime, vomit, drinks, yogurt, lol, you name it. Nothing has gone through. These covers fit perfectly. For the most part they stay in place. I do have to make adjustments when they are laid all over. But the covers do not slide down or lift up. They stay completely in place. I just have to adjust the pillows from kids and dogs. The covers hold up really well. Everything washes out of them. They don't fade, or pill. Look exactly the same way they did the first day I put them on. I have purchased a few sets now. For dogs and kids I highly recommend. I do not use the bars.
