Description

What’s in the Box
43-piece flat-pack kit including side actions, drive shaft, stabilisers, base rails, springs, handle, release cable, linkage, KD brackets and bolts. Basic assembly instructions included. Check out the “Whats in the Box” tab for a full list of parts & quantities.
Measuring Your Seat Frame Width
Measure side-to-side between the inside faces of the left and right seat rails. Choose 500mm, 550mm, 600mm or 700mm to match your frame. If you’re unsure, reach out and we’ll help confirm the correct size before you order.
Left- or Right-Hand Operation Explained
From the seated position: if you operate the release handle with your left hand, you need the LHO mechanism. If you use your right hand, choose a RHO mechanism. Matching the side of your recliners release handle ensures your new mechanism aligns with the existing linkage and handle position.
When to Replace a Mechanism?
Mechanisms can fail after impacts during moving, a heavy snag on the footrest, bent link arms, worn rivets, twisted base rails, or corrosion and fatigue over time. If the chair rocks, binds, won’t lock, or won’t recline evenly, a complete mechanism swap restores alignment and a like-new feel. This kit is a direct replacement for 4341 compatible frames used by Leggett & Platt and many similar OEM builds.
Considering a Powered Mechanism?
Some customers choose to upgrade to electric while replacing a failed manual mechanism. Powered mechanisms are available in multiple widths and sides, with compatible transformers, switches and wiring harness. Compare manual and powered options in our recliner mechanisms category (click here).

How to Install
The 4341 manual recliner mechanism kit comes flat-packed and requires assembly before fitting into your furniture. Follow the steps below with a socket set, spanner, Phillips screwdriver, and pliers (optional for spring fitting). Estimated assembly and installation time is 30–40 minutes.
Tools required:
- Socket set
- Spanner
- Phillips screwdriver
- Pliers (optional, for spring fitting)
Step 1 – Assemble the side actions and drive shaft
Lay out the left and right side actions. Connect them using the drive shaft, ensuring the largest side is in the fully retracted position. Fix in place with 2x 25mm bolts.
Step 2 – Install the stabiliser bar
Position the stabiliser bar with the 90° flat end just behind the drive shaft. Secure with 4x 13mm bolts.
Step 3 – Install the front and rear stabiliser tubes
Fit both stabiliser tubes to the frame and fix with 8x 13mm bolts.
Step 4 – Install the front and rear base rails
Attach the base rails using 4x 13mm bolts and 4x glides with nuts.
Step 5 – Fit the release linkage
Install the cable release linkage mechanism (left or right, depending on your order) with 1x 13mm bolt.
Step 6 – Attach the springs
Fit the springs in their correct positions. Use pliers if required to stretch and secure.
- 117mm lockdown spring
- 180mm footrest release spring
Step 7 – Install the mechanism into your furniture
Position the assembled mechanism into your recliner frame and secure using the original fixings and mounting points from your old mechanism.
Step 8 – Fit the handle and cable
Install the supplied oval plastic handle and release cable with a Phillips screwdriver. If reusing an existing handle style, fit that instead (plastic oval, small oval, paddle lever, or D-pulley parachute).
Step 9 – Refit the backrest
Slide the backrest into position. If you need to adjust or replace the KD brackets supplied with the kit, do so now, reusing your original fasteners if required.
Step 10 – Test the recliner
Once everything is secured, sit in the chair and operate the handle or lever to confirm smooth opening and closing. Check that the springs engage correctly and the mechanism locks firmly in place.

FAQs
FAQs
What sizes are available and how do I measure correctly?
We stock 500 mm, 550 mm, 600 mm and 700 mm seat widths. To measure your recliner, take the recliner mechanism out and measure side-to-side between the inside faces of the two seat rails (left to right). Match this measurement as closely as possible to one of our standard sizes before ordering.
How do I know if I need left-hand or right-hand operation?
Sit in your recliner as normal. If you use your left hand to pull the release handle, you need a left-hand mechanism. If you use your right hand, then you need a right-hand mechanism. This ensures the handle position matches your existing setup.
Can I upgrade my manual recliner to an electric version?
Yes, you can. We supply a range of complete electric recliner mechanisms and upgrade kits. These allow you to transform your manual recliner into a powered version with simple push-button or remote control operation.
What tools do I need to assemble and install the kit?
You will need a socket set, spanner, and a Phillips screwdriver. Pliers are optional but can help when fitting the springs. All fixings and components are supplied in the kit, so no additional parts are needed.
Is this mechanism compatible with different handle styles?
Yes. The kit is supplied with a large metal oval handle and release cable, but it can also work with small oval handles, plastic handles, paddle levers, and D-pulley parachute style releases. You can reuse your original handle or purchase an alternative from our range.
Do you offer an assembly service?
No, we do not. This mechanism is supplied only as a flat-pack kit for worldwide shipping. It is designed for DIY assembly and installation with basic tools and handyman skills.
