Furniture items can be recycled in exchange for tokens using the recycling bin. To access this you will need to be in furniture decorating mode (tap the cushion icon on the bottom toolbar) and then when you tap and drag an item in your haven you can drag it down to the recycling bin icon in the lower left. The game will ask you to confirm this and tell you the amount of tokens you will receive.
Please note: This cannot be undone once recycled and due to the safeguard in place we do not reinstate furniture that has been recycled.
