Are you struggling with your mattress constantly sinking in the middle? Do you wake up every morning with back pain and aches? Let’s put slats in your bed.
Putting slats in a bed is an essential step to ensure proper support for your mattress and enhance the stability of your bed frame.
Whether assembling a new bed or replacing damaged slats, understanding the process can make the task straightforward and manageable. With the right tools, clear instructions, and patience, you can securely position slats for a comfortable and durable sleeping surface.

This guide on how to put slats in a bed will walk you through the necessary steps to complete the task efficiently. Let’s get started.
What Are the Benefits of Putting Slats in a Bed?
Before we dive into the process, let’s first understand why putting slats in a bed is essential.
- Proper Support for Your Mattress: A sturdy and well-positioned set of slats ensures that your mattress receives even support throughout its surface. This prevents sagging or sinking in the middle, which can lead to discomfort and poor sleep quality.
- Enhanced Stability: Slats are a foundation for your bed frame, providing additional stability and preventing it from shifting or wobbling while you sleep.
- Improved Air Circulation: Placing slats in your bed allows for better air circulation underneath your mattress, reducing the risk of mold and mildew growth.
- Cost-Effective: Buying a set of slats is more cost-effective than purchasing a new box spring or foundation for your bed.
What Will You Need?
Before you begin, make sure you have the following tools and materials on hand:
- Measuring tape
- Saw (if cutting slats to size)
- Sandpaper (to smooth any rough edges)
- Screws or nails (depending on your bed frame)
- Screwdriver or hammer
Once you have all the necessary tools and materials, it’s time to start putting slats in your bed.

8 Easy Steps on How to Put Slats in a Bed:
Step 1: Measure Your Bed Frame
Start by measuring your bed frame’s inside width and length with a measuring tape. These measurements will determine the size of the slats you need. Ensure accuracy by measuring from one side to the other at both the head and foot of the bed, as some bed frames may not be perfectly rectangular.
When cutting the slats to size, write down these dimensions to ensure they will fit snugly within the frame. If your bed frame has a central support rail, remember to account for it when measuring and installing the slats. Proper measurements are crucial for preventing gaps or misalignment, ensuring the slats adequately support your mattress.
Step 2: Cut the Slats to Size
Using the measurements you recorded, cut the wooden slats to the correct length with a saw. Ensure that each slat is cut evenly to avoid gaps or uneven support. If you purchased pre-cut slats, double-check their size against your measurements to confirm they fit properly.
Smooth the edges of the slats with sandpaper to prevent splinters or damage to the bed frame. Accurate and well-prepared slats are essential for creating a sturdy and reliable foundation for your mattress.
Step 3: Position the Slats on the Frame
Place the slats evenly across the bed frame, consistently spaced for optimal support. If your bed frame includes a central support rail, position the slats so they rest securely on it, dividing the weight evenly.
Use a measuring tape or spacer to maintain equal gaps between the slats, as uneven spacing can cause weak spots in the foundation. Ensuring proper placement will help distribute the mattress’s weight evenly and improve its durability.
Step 4: Secure the Slats in Place
Once the slats are positioned evenly, secure them to the bed frame to prevent shifting or movement. Depending on your bed frame design, this may involve using screws, nails, or brackets to hold the slats firmly in place.
If screws are required, pre-drill small holes to prevent the wood from splitting, and then carefully fasten each slat. For frames with built-in slots, ensure that the slats are fully inserted and locked into position. Properly securing the slats ensures the bed frame remains sturdy and prevents unnecessary wear or noise over time.

Step 5: Test the Stability of the Bed Frame
After securing the slats, test the stability of the bed frame to ensure it is correctly assembled. Carefully press down on different areas of the slats and wiggle the frame gently to check for any movement or creaking.
If you encounter instability, revisit the slats and fastenings to verify that everything is securely in place. Ensuring a stable frame not only provides better support for the mattress but also increases your bed’s overall longevity and safety.
Step 6: Attach the Headboard (If Applicable)
If your bed frame includes a headboard, this is the point to attach it. Align the headboard with the designated slots or mounting points on the frame, and ensure it is positioned evenly.
Use the provided screws, bolts, or brackets to secure the headboard tightly to the frame. Check that all connections are properly tightened to prevent wobbling or instability. A securely attached headboard enhances the bed’s appearance and provides additional support for sitting up comfortably.
Step 7: Place the Mattress on the Frame
Carefully lift the mattress and position it evenly on the bed frame. Ensure that the mattress aligns appropriately with the edges of the frame and does not overhang.
Adjust the mattress to sit flat and level, providing a stable and comfortable sleeping surface. Double-check that the frame supports the mattress thoroughly, especially if using slats, to avoid sagging or uneven distribution. With the mattress in place, your bed is now ready for use.
Step 8: Add Bedding and Final Touches
Once the mattress is securely in place, it’s time to add your bedding. Start with a fitted sheet, ensuring it wraps snugly around the mattress. Next, layer on a flat sheet followed by blankets, a comforter, or a duvet, depending on your preferences and the weather.
Arrange pillows neatly at the head of the bed, adding decorative cushions if desired for an extra touch of style. Take a moment to smooth out any wrinkles or folds in the bedding for a polished look.
By following these 8 simple steps, you can easily add slats to your bed frame and create a sturdy foundation for your mattress.

5 Things You Should Avoid
- Using the Wrong Size Slats: Ensure the slats are the correct size for your bed frame. Slats that are too short or too long may cause instability, leading to a weak foundation for your mattress.
- Not Securing the Slats Properly: Avoid leaving the slats loose or unsecured. Failing to fasten them to the bed frame can result in shifting and an uneven sleeping surface.
- Ignoring the Weight Capacity: Be cautious of the slat material and design to ensure they can handle the weight of the mattress and sleepers. Using weak or flimsy slats may cause breakage over time.
- Spacing Slats Too Far Apart: Make sure slats are evenly spaced with minimal gaps. Excessive spacing can cause sagging or damage to your mattress, reducing its longevity.
- Skipping Installation Tools: Don’t install slats without the proper tools, such as measuring tape, screws, or a screwdriver. Using the wrong tools or skipping them entirely can result in an improper fit or assembly.
Do Bed Slats Need to Be Screwed in?
Bed slats are essential to any bed frame, providing support for your mattress and ensuring a comfortable sleep experience. While there are different types of slats available, including flat, curved, or sprung slats, one question that often arises is whether or not they need to be screwed in.
The short answer is yes – bed slats do need to be screwed in for proper installation and stability. This is especially important if you have a platform bed frame or a bed without traditional side rails. The slats may shift and move around without proper securement, causing an uneven sleeping surface and potentially damaging your mattress.
Screwing in bed slats also helps distribute weight evenly and prevent sagging or breaking of the slats over time. It is essential to use the correct screws and tools for installation, as using the wrong ones can also lead to improper fit and potential damage.
In addition, screwing in bed slats may also be necessary for safety reasons. If you have young children or pets that may jump on the bed, securing the slats can prevent accidents such as falling through gaps between slats or having a loose slat break under weight.

Conclusion
How to put slats in a bed may seem like a simple task, but it is crucial to ensure proper installation and avoid potential issues.
Once the bed frame is ready, position the slats evenly across the base, ensuring they are aligned and provide full coverage for mattress support. Use the appropriate screws and a power drill or screwdriver to attach each slat to the frame or designated rail securely. Double-check that all slats are fastened tightly to avoid any movement.
Finally, inspect the bed for stability and ensure the slats are correctly installed before placing the mattress on top. Taking these steps provides a safe, durable, and comfortable sleeping surface.
