I bought my dream sofa about 3 months ago, which is the famous cloud couch/modular couch, whatever you wanna call it.So, I’ve been dealing with each piece sliding every time I sit on it, esp if you’re doing *other* activities on it, they will just slide completely apart and you’ll fall thru. Well, I finally had enough and searched for a way to connect them without damaging my beloved sofa.I found these, and holy smokes, they work GREAT. I took advice from another reviewer, and bought two for each connection point, just to make sure it’s super secure and sturdy, and I am in love. They work great, don’t slide anymore. Even though my couch is on hardwood. I can’t rave enough, and I HIGHLY recommend using two for each contact point, especially if you own the 43” deep cloud couch.Just get them, they’re easy to install, and work phenomenally.
