Lesson Content/Board Summary

CONSTRUCTION OF SIMPLE UPHOLSTERY ARTICLE

Identification Process of Upholstery Construction

Upholstery construction is the process of covering furniture frames with padding, springs, webbing, and fabric or leather. It transforms a bare frame into a comfortable and aesthetically pleasing piece of furniture.

The main stages in upholstery construction are:

Frame preparation
Webbing and spring installation (if applicable)
Padding and wadding installation
Cover fitting and fastening
Finishing checks

Step-by-Step Upholstery Construction

The construction of a simple upholstered article involves a sequence of steps to ensure durability and a good finish.

The general steps are:

Prepare the furniture frame.
Install webbing (if required for support).
Apply padding and wadding.
Cut and fit the fabric cover.
Fasten the fabric securely.
Perform final checks and detailing.

Frame Preparation

Frame preparation involves ensuring the furniture frame is strong, clean, and smooth. Any loose joints are tightened, and rough edges are sanded. This stage is important for the overall stability and longevity of the upholstered article.

Padding Installation

Padding installation involves attaching materials that provide comfort and shape to the furniture. These materials are placed over the frame and webbing.

Common padding materials include:

Foam (various densities)
Wadding (polyester or cotton)
Felt
Rubberized coir

The padding is cut to size and glued or stapled to the frame, building up the desired shape.

Cover Fitting and Fastening

Cover fitting involves cutting the chosen fabric accurately according to the dimensions of the padded frame. The fabric is then carefully positioned over the padding, ensuring it is smooth and free from wrinkles. Fastening involves securing the fabric to the frame.

Tools used for fastening include:

Staple gun
Tacks and hammer
Upholstery needles and thread

The fabric is pulled taut and stapled or tacked to the underside or hidden parts of the frame.

Finishing Checks

Finishing checks are the final inspection and detailing steps to ensure the upholstered article is complete and well-made. This includes trimming excess fabric, adding decorative elements like piping or buttons, and ensuring all fastenings are secure and hidden. The finished product should be neat, comfortable, and aesthetically pleasing.
