Couches and similar furniture pieces may slide on hardwood floors whenever you sit on or get up from the furniture, or bump into it. There are two different products that, when placed on the bottom of the couch legs, stop the couch from sliding without you needing to perform any real "handy work."
Measure the width and length of the bottom of each of the couch legs.
Add between ¼ and ½ inches to the two measurements. For example if the measured length was 1 inch and the measured width was ½ inch, the final values would be 1 ½ inches in length and 1 inch in width.
Cut the plastic furniture mats or gripper pads into the size (1½ inches in length and 1 inch in width for this example). Cut the mats or pads into the same shape as the bottom of the couch legs.
Lift each side of the couch and place or slide two cut furniture mats or gripper pads underneath the two legs on each end of couch. Make sure the legs of the couch are resting evenly on the mats or pads. If using gripper pads, place the ribbed side of the pads facing up toward the ceiling.
Sit on the couch to ensure the couch is not wobbly and to press the couch legs into the mats or pads.
Use caution when lifting heavier couches or ask a friend or family member for help when moving the couch to prevent injury.
