How to Fix a Sagging Dresser Drawer Bottom in 10 Minutes

If you own flat-pack furniture, you are likely familiar with the dreaded sagging drawer bottom. Over time, the thin hardboard panel at the bottom of the drawer bows under the weight of your clothes, eventually slipping out of the shallow grooves on the sides. Suddenly, your drawer is unusable, catching on the frame below it every time you try to open it.

You do not need to buy a new dresser or purchase expensive replacement parts. You can permanently reinforce a sagging drawer bottom in about 10 minutes using basic household tools and scrap materials.

Tools and Materials Needed

• A wooden paint stir stick (or a sturdy wooden ruler/yardstick)
• Two small wood screws (about 1/2-inch to 3/4-inch in length)
• A screwdriver
• Wood glue or hot glue
• A handsaw or utility knife (to trim the wood stick)

Step 1: Empty and Align the Panel

Remove the drawer entirely from the dresser and empty all of its contents. Turn the drawer upside down on a flat surface. Locate where the thin bottom panel has bowed and slipped out of its guiding grooves. Gently push the panel back into the grooves on the front, back, and side panels of the drawer until it sits flat and square.

Step 2: Size Your Support Slat

To prevent the bottom from bowing again, you need to install a central support beam underneath it. Take a wooden paint stir stick or a wooden ruler and lay it across the bottom of the drawer, running from the front frame to the back frame. Mark the stick where it meets the solid wood or MDF edges of the drawer frame. Use a utility knife or a small hand saw to cut the stick to this exact length.

Step 3: Secure the Support Slat

Apply a thin line of wood glue or hot glue along one side of your newly cut wooden slat. Place the slat glue-side down directly across the middle of the sagging drawer bottom, running from front to back. Press down firmly to bond it to the sagging panel. Next, drive a small wood screw through each end of the slat directly into the solid front and back frames of the drawer. Make sure your screws are short enough that they will not pierce all the way through to the outside of the drawer front!

Step 4: Reinforce the Grooves with Glue

While the drawer is still upside down, run a generous bead of wood glue or hot glue along the entire perimeter where the bottom panel meets the side grooves. This acts as an extra layer of structural support, preventing the panel from shifting or sliding out of the tracks in the future.

Step 5: Reinstall the Drawer

Allow the glue to dry completely (about 30 minutes for wood glue, or just 5 minutes if you used hot glue). Once dry, flip the drawer over and slide it back into your dresser. You will find that the bottom is now rigid, perfectly flat, and fully capable of holding your clothes without bowing again.
