How to Fix a Sagging Mattress With Plywood

A sagging mattress can be a major nuisance, causing discomfort and disrupted sleep. Over time, mattresses tend to lose their firmness and support, resulting in a sagging surface. While purchasing a new mattress may seem like the only solution, there is a cost-effective alternative that can help revive your sagging mattress – using plywood. In this article, we will discuss how to fix a sagging mattress with plywood and address some common questions related to this method.

Materials Needed:
– Measuring tape
– Plywood board(s)
– Saw (if required)
– Sandpaper (if required)
– Screwdriver
– Screws

Step-by-step Guide:

1. Measure your mattress: Start by measuring the dimensions of your mattress, including the length, width, and thickness. This will help you determine the size of plywood board(s) needed.

2. Purchase plywood: Visit a local hardware store or home improvement center to purchase the required plywood. Opt for a sturdy and thick plywood board that can provide adequate support to your mattress.

3. Prepare the plywood: If the purchased plywood board does not match the dimensions of your mattress, you may need to cut it to the desired size using a saw. Ensure that the edges are smooth and free from splinters by sanding them with sandpaper.

4. Clean your mattress: Before placing the plywood on your mattress, make sure to clean it thoroughly by vacuuming or spot cleaning any stains. This will prevent dirt and debris from getting trapped between the mattress and plywood.

5. Position the plywood: Carefully lift the mattress and place the plywood board(s) directly on the foundation or slats, ensuring that it covers the entire sagging area. If you have a queen or king-size mattress, you might need two smaller boards to cover the entire surface.

6. Secure the plywood: Using a screwdriver and screws, secure the plywood board(s) to the bed frame or slats. Make sure the screws do not extend beyond the plywood surface to avoid any discomfort while sleeping.

7. Test the difference: Place the mattress back on top of the plywood and lie down to test the difference. You should notice improved support and fewer sagging areas.
