I bought these to put under the Love Sactional seat and use as an ottoman as I wanted it to roll. I measured the screw in the leg from the love bag and figured I bought equal sized rolls (1/4). However, they were too small and I had to use tape to hold them tight enough so they wouldn't fall out. After that everything was perfect. I hated trying to pull the ottoman closer and this was the perfect solution. They can easily be replaced with a leg the next time I want to rearrange the sofa. I can't tell if it's not 1/4, I probably measured it wrong.
