How to Anchor Furniture Onto Concrete Flooring

Look at each piece of furniture to see how it will best be attached to the floor. The straps and connectors you use depend upon the type of furniture. For example, a chair with a tube running along the concrete as its base would use upside down U-shaped straps that fit over the tubes on each side. A picnic table with the traditional four legs would use right-angle straps on at least two legs, with one side of the strap screwed into a leg and the other into the concrete.

Set your furniture into place. Removing the screws to move the furniture at a later time is possible but it will leave holes in the concrete surface that will need to be patched.

Fit the strap or bracket to the piece of furniture where appropriate. Look for a strong spot that will prevent the furniture from twisting and breaking if someone picks it up. Some furniture might be large enough to require multiple connections.

Mark the spot on the floor where the anchor screw will go and then remove the furniture. Drill the appropriate sized hole into the concrete to match your screw. Hold the drill steady to ensure that it does not drift to either side, making the hole larger than you want. Clear away the dust and debris.

Place the furniture back on the pad and the strap over the hole. Set the screw into the concrete hole through the hole in the strap and screw it into the hole. Test the furniture by attempting to pick it up.
