There are connectors that come with the hardware that can be used to lock all pieces together. However, I slept on this with my 9 yo nephew and had no problem with the pieces slipping apart without the connectors and I like the flexibility of being able to pull them apart to make a conversation circle. These are not made of your grandmother's wicker. These are wicker resin and are substantial pieces of furniture. The cushions have a high friction backing that holds them in place well. I was thinking I would sew some lanyards to the cushions because we can have wind, but I do not think that this will be necessary. I am happy with it and find it is staying in place beautifully. Exceeded expectations for my needs.
