How to Lubricate a Murphy Bed Mechanism
Short answer: To keep a Murphy bed operating smoothly, lubricate the moving parts of the mechanism, such as hinges and pivot points, with a dry silicone or PTFE spray. Avoid oil-based lubricants that attract dust and can damage finishes. Apply lubricant every six months or when you notice increased friction or noise. Always follow the maker's instructions for your specific model, and never lubricate gas pistons or springs unless the maker says to do so.
Why Lubrication Matters for a Murphy Bed
A Murphy bed mechanism relies on springs, pistons, and hinges to fold the bed up and down. Over time, friction at the pivot points can make the motion feel less smooth. Regular lubrication reduces that friction, which can help the mechanism work as intended and may extend the life of the moving parts. This is especially important for beds that are used daily, such as in a home office that converts to a guest room, or for a studio apartment where the bed is the main sleeping surface.
Lubrication is not a substitute for proper maintenance. Before applying anything, check the maker's instructions for your specific bed. Some mechanisms are sealed and should never be lubricated. When in doubt, contact the maker. The maker's instructions are the final authority on what is safe for your particular model, whether it is a wall bed, a cabinet bed, or a DIY kit.
Which Lubricants Are Safe for Springs, Pistons, and Hinges
For hinges and pivot points, a dry lubricant such as silicone spray or PTFE (polytetrafluoroethylene) spray is a safe choice. These lubricants dry to a film that reduces friction without leaving a sticky residue that attracts dust and dirt. They are also less likely to damage wood or painted finishes, which is important for a cabinet bed that is part of your room's decor.
Avoid oil-based lubricants like WD-40 or general-purpose oils. They can attract dust, which may create a gritty paste that increases wear. They can also stain wood or damage the finish on a cabinet bed. If you have a bed with a wooden cabinet, an oil-based lubricant can seep into the wood and cause discoloration.
Gas pistons and springs are different. These components are often sealed and pre-lubricated by the maker. Adding lubricant to a gas piston can interfere with its operation. Only lubricate springs or pistons if the maker's instructions specifically say to do so. For example, some wall beds use a spring lift mechanism, while others use pistons; the care for each is different.
- Dry silicone spray: safe for hinges and pivot points, leaves a dry film.
- PTFE spray: similar to silicone, good for metal-on-metal contact.
- White lithium grease: can be used sparingly on heavy-duty hinges, but it may attract dust.
- Never use oil-based lubricants on wood or painted surfaces.
- Never lubricate gas pistons unless the maker instructs it.
How to Apply Lubricant Safely
Before applying lubricant, clean the area around the hinges and pivot points with a dry cloth to remove dust and debris. Then spray a small amount of lubricant onto a cloth or directly onto the moving parts. Wipe off any excess to avoid drips. This is especially important for a bed with a desk, where the mechanism is close to the work surface.
Apply lubricant only to the moving parts of the mechanism, not to the mattress, fabric, or wood surfaces. If you are unsure where to lubricate, refer to the maker's instructions or contact the maker for guidance. For a cabinet bed, the hinges are often inside the cabinet, so you may need to open the bed partway to access them.
After applying, open and close the bed a few times to work the lubricant into the joints. This also helps you see if the motion improves. If you notice any resistance or unusual sounds, stop and check the mechanism for loose parts or damage.
How Often to Lubricate
As a general rule, lubricate the hinges and pivot points every six months. If you use the bed daily, you may need to lubricate more often. If you notice increased friction, squeaking, or stiffness when folding the bed, that is a sign it is time to lubricate. For a guest room bed that is used occasionally, an annual check may be sufficient.
Lubrication is not a one-time task. Regular maintenance keeps the mechanism operating smoothly. Add lubrication to your seasonal home maintenance checklist, such as when you change the clocks or prepare the guest room for visitors. This is particularly useful for a bed in a home office that is used for occasional guests, as you want it to be ready when needed.
If you have a Murphy bed kit that you assembled yourself, you may need to lubricate more frequently because the components may not be as finely tuned as a pre-assembled bed. Follow the kit's instructions for maintenance.
What Not to Do
Do not over-lubricate. Too much lubricant can attract dust and create a mess. A small amount is enough. A thin film is all that is needed to reduce friction.
Do not use lubricants on the mattress or the cabinet interior. They can stain fabrics and damage the finish. If you have a mattress that stays on the bed when folded, be especially careful not to get lubricant on it.
Do not lubricate the locking mechanism unless the maker says to. Some locks are designed to stay dry for safety. Lubricating a lock can cause it to fail, which could be a safety hazard.
If your bed has a motorized mechanism, do not lubricate the motor or electrical components. Only lubricate the mechanical parts as directed by the maker. Motorized beds have different maintenance needs, and adding lubricant to the motor can cause damage.
When to Call the Maker
If lubrication does not resolve stiffness or noise, the issue may be more than friction. Worn hinges, a damaged spring, or a failing piston may require replacement. Contact the maker for guidance. Attempting to repair a mechanism without proper knowledge can void the warranty or cause injury.
Some makers, like Wilding Wallbeds, offer a lifetime warranty on lifting mechanisms. If your mechanism is under warranty, the maker may repair or replace it. Always check the warranty terms before attempting any repair yourself. For other brands, such as Night and Day Furniture, warranty coverage may vary by model, so check the product documentation.
If you are unsure about the type of mechanism your bed uses, refer to the product listing or the maker's website. For example, a wall bed may use a spring lift or a piston lift, and the care instructions differ. Knowing your mechanism type helps you decide whether lubrication is appropriate. You can also read more about springs vs. pistons to understand the differences.

Questions
Can I use WD-40 on my Murphy bed hinges?
WD-40 is an oil-based lubricant that can attract dust and may damage finishes. It is better to use a dry silicone or PTFE spray designed for hinges and pivot points.
Do I need to lubricate the gas pistons on my Murphy bed?
Gas pistons are usually sealed and pre-lubricated. Do not lubricate them unless the maker's instructions say to do so. Adding lubricant can interfere with their operation.
How often should I lubricate my Murphy bed?
As a general rule, lubricate the hinges and pivot points every six months. If you use the bed daily or notice friction, lubricate more often.
