Got a saggy sofa? This Pinterest user has the fix!

"Fix it easy (and for under $20) with zip-ties! I uses the 11-inch long ones (100 pack for about $8) and it took 1.5 bags for a regular sofa. First pull off the bottom batting/fabric. Check the springs and make sure there are no broken ones. Start by zip-tying the S springs around the wooden frame (at the top and bottom of each S spring.) Then start on one side and zip-tie diagonally all the way across. Try it!"
