Review on Ultimate Protection: MZhugz Cat Couch Protector - Heavy Duty Anti-Scratching Mat for Sofa, Easy Installation by Tina Wells

Seems to help prevent scratching of furniture. However, they may also lack the ability to attach themselves firmly to furniture. There are no instructions on the packaging, so you have to guess that the velcro straps should go around the legs of the furniture. This is a serious problem for people with disabilities, rendering them partially unusable, causing the lid to dangle somewhat for this reason. Also, the product descriptions don't tell the buyer that you must have furniture with removable cushions in order for it to be attached properly, otherwise you'll have to make your own modifications.
