Un-zip your couch cushion
Slide SagsAway inside the cushion cover and underneath the bottom of your cushion for a snug fit
Zip the cushion cover back up (you might need help temporarily compressing the cushion to re-zip it)
THE TIGHTER THE FIT..THE BETTER THE SIT!
Because this goes inside your zippered cover, you can customize for any size cushion.
This solution is all about compression of your remaining foam density.
You can customize SagsAway for any size seat cushion! Use a straight edge and a utitilty knife to trim the SagsAway insert to match the dimensions of your cushion.
SagsAway works by restoring the compression of your cushion's foam density, so coverage is required only for parts of the cushion that are sat on.
