However, if you plan to use it as a place to host guests, you can have more throw pillows on your sofa to decorate it. Additionally, you can consider whether the sofa will be your primary seat for the room or an accent sofa for decoration in the room.
This will also play a role in the number of throw pillows you will need. The shape and placement of the throw pillows matter. For example, you can use square throw pillows to visually layer the sofa.
Lumbar throw pillows has a different shape than square throw pillows and take up less of the depth of the seat. Therefore, they can be beneficial on deep sofas if you want to provide support for your guests backs without taking up much of their seat depth. The arrangement of the throw pillows will affect the total count of the throw pillows.
