Sofa Bed Leveling Guide

1 Clear the Area and Inspect the Frame

Remove all cushions, bedding, and stored items from the sofa bed. Pull it away from the wall so you have access to all sides. Inspect the frame for any visible damage, such as cracked wood, bent metal, or loose joints.

If you find structural damage, address it first. Refer to our guide on sofa bed joint construction to understand how your frame is assembled. For metal frames, check our metal frame sofa bed guide. For wooden frames, see solid wood frame sofa beds.

2 Identify the Problem Area

Place a spirit level on the seat frame (not the cushions) and check both front-to-back and side-to-side. Note where the bubble is off-center. Then, check each leg individually by placing the level on top of the leg or using a measuring tape from the floor to the bottom of the frame.

Common causes of unevenness include:

• Uneven flooring (tiles, hardwood planks, or carpet transitions)
• Worn or damaged leg glides
• Missing or loose leveling feet
• Warped frame components
• Improper assembly after moving

If you recently assembled the sofa bed, review our sofa bed assembly guide to ensure everything was installed correctly.

3 Start with the Simplest Fix: Shims

For minor unevenness (less than 1/4 inch), shims are the quickest solution. Slide a wooden or plastic shim under the shortest leg until the frame is level. Use the spirit level to confirm.

Tip: Trim excess shim material with a utility knife so it doesn't stick out. For a cleaner look, use rubber or cork shims that grip the floor better. If your sofa bed has coasters, you can also place shims under the coasters for a temporary fix.

4 Install Adjustable Leveling Feet

Adjustable leveling feet are the most reliable solution for uneven floors. They screw into the bottom of the sofa bed legs and can be raised or lowered by turning them. Most sets cost between $15 and $40.

To install:

• Check the diameter and thread type of your existing leg holes. If your sofa bed has tapered or decorative legs, you may need adapter plates.
• Remove the existing glides or feet.
• Screw in the new leveling feet by hand, then fine-tune with a wrench.
• Adjust each foot until the sofa bed is perfectly level.

For heavy sofa beds, choose leveling feet rated for the weight. A sectional sleeper sofa may require heavier-duty feet than a small sofa bed.

5 Address Floor Protection and Stability

Once the sofa bed is level, add non-slip sofa bed pads under the legs to prevent sliding and protect your floors. Felt pads are ideal for hardwood and laminate, while rubber pads work better on tile.

If you have a pull-out sofa bed, make sure the leveling feet don't interfere with the mechanism. Test the pull-out function several times to ensure smooth operation. For added safety, consider anti-tip straps, especially if the sofa bed is in a guest room or children's play area.

6 Final Check and Maintenance

After leveling, sit on the sofa bed, open and close the mechanism, and lie on it to test stability. Re-check the spirit level after a few days of use — sometimes the feet settle slightly.

For long-term maintenance, periodically check the leveling feet and tighten them if needed. If you notice the frame becoming uneven again, inspect for hinge damage or mechanism issues. Regular care, including upholstery cleaning and dust prevention, will keep your sofa bed in top condition.
