I LOVE this sectional. It fits my deck perfectly. Yes, you need something to hold it together. I bought zip ties and use those, super cheap. You could also get clips. But it’s such a comfortable sectional. Working from home, I’ve spent many days out there already working on my laptop and it’s comfy. I looked at a lot of patio couches and I’m so glad. Not sure how it will hold up with it rains but so far I’m pleased.
