I have purchased 3 of these in full and queen sizes for my law office, which has 2 futons that fold into full size beds and 1 sofa that folds into a queen size bed. These items are used as sofas most of the time and I was not worried about kids in my office. But I was worried about clients that come in and sit and spill cokes, coffee etc. These covers were easy to install and they appear to be holding up great so far.
