### ⭐⭐⭐⭐⭐ Wonderful support for a couch
*by S***L on September 11, 2026*

The boards work wonderfully on my couch. Some have said they’re a little hard, I agree. But I think that’s mostly due to the bad shape of my cushions. My couch is a strange size so I had to order a longer board. The seller was extremely helpful in this regard. He answered my questions, thoroughly, and quickly. Because of the design of the board we were able to fold down a piece of it. It then fit my couch great!
