Before you start, familiarize yourself with the components of your sectional couch. Typically, it consists of a left and right armchair, a right and left sofa, and a corner piece. Some may also include a chaise or ottoman. Each piece is designed to connect to the others, creating a cohesive seating arrangement.

Attach the Corner Piece

The corner piece is the anchor of your sectional. Here's how to attach it to the left and right sofas:

  1. Place the corner piece on the floor, with the attachment points facing up.
  2. Position the left sofa against the corner piece, aligning the attachment points. You may need to tilt the sofa slightly.
  3. Insert the Allen wrench or screwdriver into the attachment point on the sofa and turn clockwise to secure it to the corner piece. Repeat on the other side with the right sofa.

Adding the Chaise or Ottoman (if applicable)

If your sectional includes a chaise or ottoman, attach it to the end of the sofa in the same manner as the armchairs. Ensure the attachment points are properly aligned and secured.

Test Your Sectional

Once all pieces are attached, give your sectional a gentle tug to ensure everything is secure. It's now ready to provide comfortable seating for you and your guests!

Troubleshooting Common Issues

Issue Solution
Pieces don't fit together Ensure you're using the correct pieces and that they're properly aligned. Check for any obstructions or debris in the attachment points.
Screws or bolts won't tighten Check that you're using the correct tool. If using an Allen wrench, ensure it's the right size. If using a screwdriver, try a different type (e.g., flathead vs. Phillips).
Sectional is wobbly Tighten all attachment points as much as possible. If it's still wobbly, contact the manufacturer for advice tailored to your specific couch.
