Assembly Instructions – 700mm Universal Leggett & Platt Recliner Mechanism (No Electrics)
Tools required: Socket set with 13mm socket, spanner, screwdriver, pliers (for zip ties).
Assembly time: Approx. 30 minutes.
Important: Assemble the mechanism outside the chair frame. Fit the actuator and electrics before installing into the furniture. KD backrest brackets are only fitted or adjusted at the final stage.
Step One – Lay Out and Identify Parts
- 2 × side actions
- 2 × base bars
- 3 × stabiliser bars (2 with flat ends for front/rear, 1 with 90° folded ends for centre)
- 1 × square drive shaft
- 1 × support brace
- Pair of drive link brackets
- 1 × actuator end bracket
- 4 × glide feet with lock nuts
- All bolts and nuts supplied (no washers required)
Step Two – Assemble the Base Frame
Position the base bars between the side actions. Use 4 × 13mm bolts (2 each side) in the second set of holes, not the ones nearest the edge. Leave finger-tight until alignment is complete.
Step Three – Fit the Stabiliser Bars
Install the flat-ended stabiliser bars at the front and rear. Install the stabiliser with 90° folded ends in the centre position just behind where the drive shaft will sit. Each stabiliser uses 4 × 13mm bolts (2 each end).
Step Four – Install the Drive Shaft and Support Brace
Slide the square drive shaft through the centre pivot holes of the side actions. Position the support brace over the shaft and fit the drive link brackets. Use 4 × 32mm bolts in the 4 holes nearest the centre and 4 × 25mm bolts in the outer holes.
Important: Before tightening, ensure the side actions are in the fully retracted position. The support brace must face downwards toward the floor, with the hex bolt heads pointing upward into the seat cavity. Adjust if necessary, then tighten all bolts securely.
Step Five – Attach the Actuator End Bracket
Fix the actuator end bracket to the front base frame using 4 × 16mm bolts and 4 × lock nuts.
Step Six – Fit Glide Feet
Install the 4 × glide feet with lock nuts after the mechanism is fully assembled. Tighten securely.
Step Seven – Fit the Actuator and Electrics
Attach the actuator between the front actuator bracket and the drive link brackets. Ensure the actuator is fully retracted, the mechanism is fully retracted, and the drive link brackets are correctly positioned so the mechanism will fully open and close. Once aligned, tighten fixings, connect wiring and switch, and secure all cables with zip ties (not supplied).
Step Eight – Install the Mechanism into the Furniture
Place the complete mechanism with actuator and electrics fitted into the chair frame. Secure it to the seat rails using the pre-drilled holes, ensuring correct alignment.
Step Nine – Fit or Adjust KD Backrest Brackets
Once the mechanism is installed, fit the KD backrest brackets. Replace or adjust only if your furniture requires a different angle or style.
Step Ten – Final Checks
Test the recliner through its full range of motion. Ensure smooth operation with no fouling. Confirm all bolts are tight and all cables are safely secured with zip ties.

FAQs
FAQs
How do I know if the 700mm size is right for my chair?
Measure the distance between the inside edges of the recliner’s side rails. If the gap is 700mm, this is the correct mechanism. If it’s smaller, see our 500mm version.
Can I convert my manual recliner to electric with this?
Yes, this mechanism can be used to upgrade a manual recliner to electric. Keep in mind the old pull handle will no longer be needed once converted.
Does this kit come with an actuator and power supply?
No, this listing is for the mechanism only. You will need to purchase the actuator, transformer, leads and control switch separately, or choose our full kit with electrics included.
Do you supply the complete kit with electrics as well?
Yes, we stock the full package with all electrics pre-supplied. That version includes the actuator, motor, power supply and cables, ready for a direct installation.
Is the mechanism already assembled?
No, it is supplied as a flat pack kit. Assembly is straightforward with basic DIY skills using a socket set and spanner, and usually takes around 30 minutes.
