Review: Amazing result - I was shocked how well this worked! It saved my couch
Review: They work great. Save yourself some money from buying a whole new couch - I am not being dramatic when I say I was ready to buy a new couch. These inserts are great. I have a VERY old couch so I used 2 in the center cushion and one on the other side that is most often used and sitting on it now I really feel like I could have went without buying a new couch. Oh well. I will keep the inserts and use them for extra support under the new couch anyway
