How does a recliner mechanism work?
A recliner has a mechanism under the seat that links the back, seat and legrest so they move together. Manual models release it with a handle or by leaning back; power models add a motor, a transformer and a hand control. The legrest closes under spring tension, and manufacturers warn that moving parts can injure children, pets and fingers.

Step by step
Read when to stop and call a pro, further down this page, before you start.
Step 1: Find the maker and model
Look for a label under the seat or on the frame, then find the owner's manual for that model on the maker's website. Every brand differs.
Step 2: Unplug a power recliner first
Pull the plug from the wall outlet before cleaning, moving or servicing the chair.[1]
Step 3: Clear the path
Provide a clear path for the back and legrest, with tables and rugs far enough away for the legrest to extend fully.[1]
Step 4: Check the wall clearance
On the wall-recliner model in La-Z-Boy's PowerReclineXR+ manual, fully recline the unit and leave a minimum of 2 inches between the top of the back and the wall. Check your own manual for your model.[2]
Step 5: Look for an obstruction
If the legrest stops while closing, lift it, look for an obstruction and remove it, then lower the legrest slowly.[2]
Step 6: Inspect the cord and plug
Check the power transformer, cord, plug and connectors regularly, and stop using the chair if any is damaged.[1]
Step 7: Call the dealer for anything inside the mechanism
Leave the motor, pump and frame mechanism to service personnel.[1]
A recliner is a seat on a moving mechanism. The mechanism ties the back, the seat and the legrest together so that one motion, a pull on a handle, a lean back or a press of a button, tilts the back and swings the legrest out. Manual chairs do it with your weight and a release. Power chairs do it with a motor.
The exact linkage differs between makers and models, so this page explains what is common and what the manuals warn about. For anything specific to your chair, the owner's manual for your model is the reference.
The main parts
The frame and mechanism. The frame carries a mechanism under the seat. The back, the seat and the legrest all attach to it, which is why a worn or bent mechanism can affect all three at once.
The release. On a manual recliner the release is usually a handle or lever on the side, or a lean-back action. On a power recliner it is a hand control, and the chair runs from a power transformer plugged into a wall outlet.
The spring. The legrest is spring loaded. One manufacturer's manual says it this way: "The legrest uses spring tension to close", and that it will close quickly when an obstruction is removed.[2] That is why the instruction is to release the legrest slowly rather than let it go.
The tension adjustment. Some models let you set how firmly the back resists. La-Z-Boy's power recliner manual says the unit "is equipped with a tension adjustment feature for the reclining mechanism that is preset at the factory."[1] The same manual warns to avoid tip over: "do not operate the unit with the tension adjustment wing nuts completely loosened".[1] If your chair has an adjustment, change it only as your model's manual describes.
The motor and transformer (power models). The motor and pump are sealed units. The manual's instruction is "Do not attempt to disassemble or service the pump or motor."[1] It also says to "Check the condition of the power transformer, electrical cord, plug and connectors regularly."[1]
How to use it without damaging it
Most damage to a recliner mechanism comes from loading it in ways it was not built for. The manual lists the habits to avoid. "Do not stand, sit or place extra weight on the arms, back or open legrest."[1] "Never attempt to open the legrest by pulling on it."[1] Move it slowly, and bring the back upright and close the legrest before getting out.
Give it room. The manual asks you to "Provide a clear path for operation of the chair, back and legrest."[1] Against a wall, the PowerReclineXR+ wall-recliner manual says to fully recline the unit and "leave a minimum of 2" of space between the top of the back and the wall".[2]
Moving the chair is where mechanisms get bent. The manual says: "Never move the product by the mechanism, legrest, handle, reclining back or swivel base."[1] It also says to secure the mechanism before lifting: "Before lifting the product, secure the mechanism to prevent unexpected opening or movement."[1]
Why the moving parts matter for children
The same manual states: "This product has many moving parts, serious injury can occur if not used properly."[1] CPSC staff wrote to the furniture safety standards committee about two hazard patterns in recliners: "Entrapment in the foot support lift mechanisms beneath the recliner" and "Entrapment related to the movable foot support."[3] The letter also quotes a 1996 recall describing a 1988 furniture industry guideline that "openings between the upholstered seat and leg rest should measure five inches or less", and notes staff could not identify a current voluntary standard for that gap.[3]
In practice: keep children and pets away from the mechanism, look under and around the chair before closing the legrest, and keep the hand control out of a child's reach.
What you can check yourself
Unplug a power chair first: the manual says to "Disconnect the electrical plug from the wall outlet before cleaning, moving, servicing".[1] Then check for something blocking the legrest, a pinched or damaged cord, and the wall clearance. If the legrest stalls while closing, the manual's advice is to lift it, look for an obstruction and remove it.[2]
Sagging, a bent linkage, a handle that no longer catches, grinding from the mechanism or a dead motor are repairer jobs. Read how much recliner repair costs in Virginia before you call.
Stop and call a pro if
- The chair will not close or open and something looks bent or broken under the seat. Forcing it can damage the mechanism further, and a free-moving mechanism is a pinch hazard.
- A power recliner has a damaged cord, plug or transformer. Stop using it and unplug it.[1] Contact the dealer or a repairer.
- The motor hums but nothing moves, or you smell burning. Do not open the motor or pump.[1]
- The frame has cracked or the chair tips. Stop using it until it is repaired.
- A child has been caught or pinched. Do not let anyone use the chair until it has been inspected.

Common questions
- What is inside a recliner that makes it recline?
- A mechanism under the seat that ties the back, seat and legrest together so they move as one. Manual versions release it with a side handle or a lean; power versions add a motor, a power transformer and a hand control. The exact linkage differs by brand and model, so the owner's manual is the reliable guide.
- Why does the legrest snap shut?
- It is spring loaded. One manufacturer's manual says the legrest uses spring tension to close and will close quickly once an obstruction is removed, so release it slowly.
- Can I adjust how hard the chair reclines?
- Many models have a tension adjustment, but where it is and how it works depends on the model. La-Z-Boy's power recliner manual says its adjustment is preset at the factory and warns not to run the chair with the adjustment wing nuts completely loosened, to avoid tip over. Follow your own manual.
- Is it safe to let children play on a recliner?
- No. CPSC staff has described child entrapment incidents in recliners, including under the lift mechanism and in the gap between the footrest and seat. Keep children and pets away from the mechanism and the legrest, and do not let a child operate a power control.
- Should I try to repair the mechanism myself?
- Basic checks, such as removing an obstruction or checking a power cord, are reasonable. Opening a motor or rebuilding the frame mechanism is not. One manual says to leave the motor and pump to service personnel.
