Your sofas and chairs get a lot of use with your family. Keep your furniture looking like new by periodically rotating and flipping the cushions on this furniture that allows them to keep their shape and eliminate sagging or worn out pieces.
Flip each seat cushion and move the one originally on the right to the left and move the one on the left to the right. If you cushions are down, you can also unzip the cover and fluff them up a bit. You should also flip and rotate the seat back cushions as well.
Here is a video from Room and Board that shows how it is done.
