The Classic Square Sleeper mechanism is a heavy-duty contract/residential sofa sleeper system with a number of features and benefits to ensure comfort and durability. The Classic Square is considered the easiest to operate in the industry, and is engineered with low-profile linkage to keep all metal parts below the mattress line. Its all-square tubular frame construction provides a smooth and visually appealing look with improved safety (eliminated pinch points) and comfort in the seated position.

When ordering a replacement mechanism for your sofa, finding the manufacturer and model number information for the existing mechanism is very important. This ensures that you receive the correct fit for replacement. This model replaces the Leggett and Platt 3500 Classic Square Series mechanisms. Alternately, if the label is difficult to read, you can measure the distance between the brackets where the unit mounts into the wooden frame inside the sofa.
Please look for the Leggett model number sticker on your current mechanism and match it to the model number below. The model number of your current mechanism is the only accurate way to ensure a correct replacement. Please reference the chart below to find your model number.
