How to Adjust Murphy Bed-Piston

This type of bed is ideal for any room with limited floor space – whether it’s a small studio apartment or a large family home. Now that we’ve looked at the advantages of having a Murphy Bed, let’s take some time to discuss how to adjust murphy bed-piston. By the end of this blog post, readers will have all of their questions answered on how to adjust their Murphy bed pistons easily and efficiently!

What is a Murphy Bed-Piston?

A Murphy bed-piston is a mechanism that allows the bed to be securely stored in an upright position when not in use. It consists of a set of springs and pistons that work together to assist with lifting and lowering the bed. The pistons are attached to the frame of the bed and provide support for the weight of the mattress. You can find a murphy bed-piston in both manual and automatic models, but the adjustment process is similar for both types. It’s important to know how to adjust your murphy bed-piston as it ensures that the bed stays in place and operates smoothly.

What Is the Difference Between a Wall Bed and a Murphy Bed?

Before we dive into how to adjust a Murphy Bed piston, let’s start by discussing the difference between a wall bed and a Murphy bed. A Wall bed is affixed to the wall and requires professional installation. The mechanism works by having the mattress fold onto itself when it’s resting against the wall. 

On the other hand, a Murphy Bed is more of a frame that can be taken apart and moved around more easily. Both beds work in the same way, but the Murphy Bed is easier to assemble and adjust. Additionally, the Murphy Bed is generally less expensive than a Wall bed.

Needed Materials:


You’ll need a wrench to adjust the nuts and bolts that hold the pistons in place. Make sure you have a wrench that fits properly as using one that’s too big or small may damage the bolts.


A ladder is required to reach the top of the bed frame where the pistons are located. Make sure it’s sturdy and can support your weight.


Lubricant is needed to keep the pistons running smoothly. This helps prevent friction and ensures that your bed will operate efficiently. Make sure to use a lubricant that’s compatible with metal. Otherwise, it may cause damage to the pistons.

Cleaning Cloth

A cleaning cloth will help you remove any built-up dust or debris from the pistons. This is important as it allows the pistons to move freely and prevents any potential damage.

10 Methods How to Adjust Murphy Bed-Piston

1. Check the Wall Mounts.

The first thing you should do is check the wall mounts to make sure they are secure. If the mounts are loose, tighten them with a screwdriver. Although it’s unlikely, the wall mounts could be damaged and need to be replaced. While you’re checking the wall mounts, take a look at the back of your TV to see if there are any loose cables. Make sure all the cables are connected properly and that nothing is damaged. Otherwise, you can easily damage the TV and need to replace it. If you’re not sure about the cables, consult an electrician.

2. Adjust the Tension on the Springs. 

If the bed is not staying up on its own, you may need to adjust the tension on the springs. To do this, use a wrench to turn the tension adjustment knob located on the side of the bed frame. Though some frames may vary, you will generally turn the knob clockwise to tighten the tension and counterclockwise to loosen it. Test the bed after each turn to ensure it is lifting properly. Do not over-tighten the springs; if the bed does not stay up without significant pressure, you may need to purchase new springs. You can find these at most hardware stores or contact the manufacturer for replacements.

Staying Up on Its Own

3. Lubricate the Moving Parts. 

If the bed is squeaking or sticking when you try to open or close it, you may need to lubricate the moving parts. Use a silicone-based lubricant on all of the hinges and joints. However, do not use petroleum-based lubricants, which can cause damage. Be sure to wipe away any excess with a cloth to prevent it from getting on the mattress.

Also, make sure to check the screws and bolts periodically to ensure they are secure. If any of them seem loose, tighten them with a screwdriver or an Allen wrench. With these simple maintenance steps, you’ll be able to keep your adjustable bed functioning properly and feeling comfortable for years to come. If you have a Murphy bed with piston lift mechanisms, there are a few additional steps to keep in mind.

4. Check for Obstructions. 

Make sure there are no objects blocking the path of the bed when it is opening or closing. Remove any items that may be in the way, such as chairs or tables. If there are any cords or wires that could be tangled in the mechanism, move them out of the way. Try to keep the area around the bed clear and uncluttered. While checking, also make sure that the path of the bed is not blocked by any furniture or other items. It’s important to regularly check for any potential obstructions to avoid any damage to your bed and ensure it operates smoothly. Thoroughly examine the area surrounding your bed before adjusting it to ensure there are no hazards.

5. Adjust the Gas Cylinders. 

If your Murphy bed is equipped with gas cylinders, you may need to adjust them if the bed is not opening or closing smoothly. To do this, use a wrench to turn the adjustment knob located on top of each cylinder. Though the adjustment will vary depending on the model, turning the knob clockwise generally increases tension, while turning it counterclockwise decreases tension. Make sure to test the bed after each adjustment to ensure that it is working properly. Otherwise, you may need to replace the gas cylinders. The general rule is to replace them every 3-5 years, depending on usage and wear.

 Need to Adjust Them

6. Tighten Loose Screws and Bolts. 

Check all of the screws and bolts on the bed frame and tighten any that are loose. Use a screwdriver or wrench to tighten them until they are snug but not too tight. Although the bed frame should be sturdy, over-tightening the screws can cause them to strip. However, if you find that a screw is stripped, you can use a small piece of wood or dowel to help tighten it.

The wood or dowel should be slightly smaller than the screw hole and can be inserted to give the screw more grip. It’s important to periodically check the screws and bolts to ensure that they are tight. You can also use a thread locker to prevent the screws from loosening over time.

7. Replace Worn Parts. 

If any of the parts on your Murphy bed are worn out, such as the springs or gas cylinders, you will need to replace them before adjusting anything else. You can purchase replacement parts from most hardware stores or online retailers. Although the installation process is fairly straightforward, it may be a good idea to consult with a professional if you are unsure of how to do the repair yourself. It’s important to keep replacement parts on hand so that you can easily fix any issues with your bed in the future. You can also contact the manufacturer for guidance on which parts to purchase and how to properly install them.

8. Check the Counterbalance Mechanism. 

If your Murphy bed has a counterbalance mechanism, you may need to adjust it if it is not working properly. To do this, use a wrench to turn the adjustment knob located on the side of the bed frame. Try to adjust it until the bed is stable and secure. If you are unable to adjust it, consult the manufacturer for further instructions or consider having a professional look at it. Make sure to test it several times before you consider the bed is adjusted and secured properly. Otherwise, you may risk the bed falling unexpectedly.

9. Level the Bed Frame. 

Make sure that the bed frame is level and secure before adjusting anything else. Use a spirit level to check for levelness, and tighten any screws or bolts that are loose with a screwdriver or wrench. However, do not overtighten them. Make sure that the adjustment is snug enough to keep the frame in place while still allowing some flexibility. It’s also a good idea to check for levelness again once everything has been adjusted. The bed frame should be stable and secure before moving on to the next step.

10. Replace Defective Parts Immediately. 

If any part of your Murphy bed appears to be defective, such as broken springs or worn-out gas cylinders, replace them immediately before you attempt to adjust the bed. Defective parts can cause serious injury and should not be used or adjusted. Always follow the manufacturer’s instructions for replacing parts, and consider consulting a professional if you are unsure of how to do it yourself.

While your Murphy bed may be difficult to adjust, making sure it’s structurally sound is essential. If you don’t feel comfortable adjusting the bed yourself, contact a professional to help you. With the right tools and proper care, you can keep your Murphy bed working properly for years to come.

Following these steps will help you adjust your Murphy bed quickly and safely. Remember to always check for obstructions before adjusting any parts of the bed, and replace any worn-out or defective parts immediately. With proper maintenance and adjustment, your Murphy bed should last for years without needing additional repairs.

Things to Consider When Adjusting Murphy Bed-Piston

When adjusting the piston of a Murphy bed, there are several things to keep in mind.

1. First, make sure that the rod is properly tightened to the wall. If it is not, the bed may become loose or unstable.

2. Second, make sure that the spring tension is correct. Too much tension can cause the bed to be too firm, while too little tension can make it feel too soft.

3. Third, verify that all hardware is secure and that the bed frame is properly supported.
