Sofa Assembly
Overview
• Joining pre‑drilled frames, fasteners and cushions to create a finished sofa ready for use.
• Skill level 2 / 5
• Typical duration: 1–2 hours
Safety First
Lift with bent knees to avoid back strain; ask for help with heavy sections.
Keep fingers clear when tightening bolts—frames can pinch.
Use a sharp utility knife cautiously when cutting packaging; cut away from body.
Wear eye protection if using a power driver to prevent splinter or metal shaving injury.
Maintain a clear floor to prevent tripping over hardware and tools.
Tools & Materials
Item | Purpose |
Allen keys / hex bits | Driving sofa kit bolts |
Medium Phillips screwdriver | Securing bracket screws |
Rubber mallet | Seating dowels without damaging timber |
Power driver (low torque) | Faster bolt insertion |
Utility knife & scissors | Opening cartons, trimming fabric threads |
Spirit level | Checking sofa sits level on floor |
Soft blanket or cardboard | Protecting fabric and flooring during assembly |
Thread‑locking compound (optional) | Preventing bolts loosening over time |
Step‑by‑Step
1. Unpack & Inspect
Why: Confirms all parts are present and undamaged before you start.
Pro‑tip: Lay pieces on a blanket to protect upholstery (1/3).
2. Sort Hardware & Read Instructions
Why: Matching screws, bolts and brackets to the manual avoids mid‑build errors.
3. Assemble the Base Frame
Why: A square, rigid foundation keeps arms and back in alignment.
Pro‑tip: Finger‑tighten bolts first, then fully tighten once the frame is complete—this reduces twist (2/3).
4. Attach Arms & Back Panels
Why: Side and rear panels stiffen the structure and hide fixings.
Pro‑tip: If panels slot onto metal receivers, tap gently with a rubber mallet rather than forcing (3/3).
5. Fit Legs or Feet
Why: Raises the sofa to its designed height and distributes weight evenly.
6. Install Seat Platforms & Cushions
Why: Ensures webbing or sprung platforms are located properly for comfort and longevity.
7. Final Tighten & Dress
Why: Checking every bolt, leveling the sofa and brushing fabric leaves a professional finish.
Completion Checks
Sofa sits level with no rocking or uneven gaps beneath legs.
All bolts are tight; no creaks when weight is applied.
Back and arm rests align flush with seat base.
Cushions fit snugly without visible fastener heads or loose threads.
Packaging and tools removed, leaving the area tidy.
When to call a pro instead
If your sofa has an electric recliner mechanism, complex modular layout, limited access (tight stairwells), or you lack a second person for safe lifting, booking an experienced assembler will protect both the furniture and your back while ensuring warranty‑safe installation.
