  1. Place the Seat Panel (A) upside down on a flat, protected surface with the underside facing upward.
  2. Locate the eight pre-drilled threaded holes around the edge of the seat panel.
  3. Insert one M8×30 Bolt (E) into each hole.
  4. Turn each bolt clockwise by hand until fully threaded and securely seated.
  5. Ensure all eight bolts are straight and evenly tightened 

Step 2: Attach the Legs (B) to the Seat Panel (A)

  1. Keep the Seat Panel (A) upside down with the eight installed M8×30 Bolts (E) pointing upward.
  2. Position one Leg (B) over two exposed bolts at one end of the seat panel, aligning the leg mounting holes with the bolts.
  3. For each bolt connection, place:
    • One M8 Large Flat Washer (L)
    • One M8 Lock Washer (N)
  4. Secure each bolt using one M8 Hex Nut (H).
  5. Hand-tighten the nuts first to allow slight adjustment.
  6. Repeat the same process for the remaining three Legs (B), attaching two legs on each end of the seat panel as shown in the diagram.
  7. Once all four legs are properly aligned and standing straight, tighten all M8 Hex Nuts (H) securely using a wrench.

Step 3: Attach the Backrest (C)

  1. Carefully turn the bench frame upright so the Seat Panel (A) with attached Legs (B) is standing on a flat surface.
  2. Position the Backrest (C) at the rear of the seat panel, aligning the three mounting holes on the backrest with the three corresponding holes along the back edge of the seat panel.
  3. Insert one M6×35 Cross-head Bolt (G) through each aligned hole from the backrest toward the seat frame.
  4. On the underside of each bolt connection, place:
    • One M6 Flat Washer (M)
    • One M6 Lock Washer (P)
    • Then secure with one M6 Hex Nut (I)
  5. Hand-tighten all three connections first to allow proper alignment.
  6. Once the backrest sits flush and evenly aligned with the seat panel, fully tighten all three M6 Hex Nuts (I) using a wrench while holding the bolt head steady with a screwdriver.

Step 4: Install the Left and Right Armrests (DL & DR)

  1. Position the Left Armrest (DL) on the left side of the bench, aligning its mounting holes with the corresponding holes on both the Seat Panel (A) and the Backrest (C).
  2. Insert three M6×35 Cross-head Bolts (G) through the aligned holes (as shown in the diagram):
    • One bolt connecting to the backrest
    • Two bolts connecting to the seat panel
  3. On each bolt connection, place in this order:
    • One M6 Flat Washer (M)
    • One M6 Lock Washer (P)
    • Secure with one M6 Hex Nut (I)
  4. Hand-tighten all three connections first to allow proper positioning.
  5. Repeat the same procedure for the Right Armrest (DR) on the opposite side using the remaining three M6×35 Bolts (G), Washers (M & P), and Hex Nuts (I).
  6. Once both armrests are properly aligned and level, fully tighten all M6 Hex Nuts (I) using a wrench while holding the bolt heads steady with a screwdriver.
  7. Finally, install the two Cap Nuts (K) onto the top exposed threaded posts of the armrests for a finished and secure appearance.

FAQs

1. How much weight can a standard garden bench hold?

Most standard two-seater garden benches support between 400 and 600 lbs, depending on the material and frame construction. Solid hardwood and powder-coated steel frames typically offer higher weight capacity. Always check product specifications and ensure proper assembly for maximum stability and safety.

2. Should a garden bench be anchored to the ground?

Anchoring is recommended in windy areas, public spaces, or uneven ground to prevent shifting or tipping. Ground anchors or bolting into concrete provide added stability. For sheltered patios or private gardens, a well-balanced freestanding bench is usually sufficient.

3. How do you clean and maintain a wooden garden bench?

Clean regularly with mild soap and water to remove dirt and debris buildup. Light sanding helps smooth rough areas before reapplying outdoor wood oil or sealant. Annual maintenance protects against moisture damage and extends the bench’s lifespan.

4. How do you make a garden bench more comfortable?

Add weather-resistant cushions with UV-protected fabric for extra support and softness. Position the bench in partial shade to prevent overheating during warmer days. Small additions like lumbar pillows or armrest pads significantly improve overall seating comfort.
