Armchair Assembly
Overview
• Assemble a flat-pack or part-assembled armchair ready for use in a living space. • Skill level 2 / 5 (basic DIY competence). • Typical duration : 1–2 hours hands-on.
Safety First
Watch for finger pinch points when joining seat and arm sections.
Lift with knees bent—upholstered frames are awkward and heavy.
Keep packing staples and plastic bags away from children and pets.
Wear safety specs if drilling pilot holes for extra screws.
Use a dust mask when cutting foam off-cuts or trimming fabric.
Tools & Materials
Item | Purpose |
Phillips screwdriver or electric driver (low-torque) | Tighten main screws/bolts |
Allen (hex) keys | Often supplied for cam or barrel bolts |
Rubber mallet | Nudge joints together without marking timber |
Long-nose pliers | Remove packing staples/clips |
Soft blanket or cardboard sheet | Protect floor and fabric while working |
Spirit level | Check chair sits true on all four feet |
Thread-locker (medium strength) | Reduce fastener loosening over time |
Spare felt pads | Prevent floor scratches once assembled |
Step-by-Step
1. Unpack and Inspect
Lay a blanket and spread out all parts. Why: Prevents scratches and confirms everything is present before starting.
Pro-tip: Photograph the parts layout—handy if you need warranty support later.
2. Identify Hardware & Read Instructions
Sort screws, dowels and brackets into separate piles; skim the manual. Why: Reduces assembly errors and saves hunting for the right fastener mid-build.
Pro-tip: Match each screw size to the manual diagram with masking-tape labels.
3. Assemble Seat Frame.
Join side rails to front and back rails using supplied bolts/dowels.
Why: The seat frame is the structural core; square alignment avoids future squeaks.
Pro-tip: Tighten bolts only halfway first—fully tighten once the frame is squared.
4. Fix Arms to Frame
Stand seat frame on its side; attach arm sections with bracket screws.
Why: Gravity helps the arms locate flush; reduces strain on screw threads.
Pro-tip: Rest the arm on a box to keep it level while you start the first screws.
5. Fit Backrest
Slide or bolt the backrest into place as per kit design.
Why: Ensures load is transferred evenly and the chair feels solid when leaned on.
Pro-tip: If slots feel tight, tap gently with a rubber mallet rather than forcing screws.
6. Attach Legs or Base
Screw in legs or clip the swivel base, checking thread orientation.
Why: Incorrect leg placement can affect height or stability.
Pro-tip: Add felt pads before turning the chair upright to protect hard floors.
7. Tighten & Level
Fully tighten all fixings, then flip the chair upright and test wobble. Why: Final torqueing locks joints; levelling avoids strain on one leg.
Pro-tip: Use a spirit level across arm tops—shim under short legs with felt pads.
8. Install Cushions & Finish
Position seat/back cushions, fluffing fibre fill for shape.
Why: Allows foam to expand and fabric creases to settle.
Pro-tip: Steam-remove stubborn creases with a garment steamer held 5 cm away.
Completion Checks
Chair sits level without rocking.
All bolts tight and flush—no visible gaps at joints.
Fabric or leather free from staple snags and fingerprints.
Cushions aligned, zips closed, tags/stickers removed.
No leftover screws or washers.
When to call a pro instead
If the chair is designer-grade with complex reclining or swivel mechanisms, requires upholstery stapling, or you lack space to work safely, a professional furniture assembler can complete the job quickly without risking frame damage or voiding the warranty.
