Designed for the Leggett & Platt Classic Square 3500 Series Sleeper Sofa Mechanism. Components sizes vary by width and can accommodate both residential and contract markets. Contract markets include hotels, motels, and resorts.
The sleeper sofa repair kit does not include the sleeper sofa replacement mechanism. Most often, sleeper sofas just require the replacement of the polypropylene deck that supports the mattress. Each kit contains a replacement polypropylene deck along with (10) helical springs for perimeter attachment of the deck to the old sleeper sofa mechanism. If the original sleeper sofa mechanism is still in good working order, it is more cost-effective and easier to just replace the polypropylene deck.
Model Number Information: Please look for the Leggett & Platt 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. The widths listed below are the mounting bracket to mounting bracket measurements. This is how the manufacturers determine the size. Please reference the chart below to find your model number.

If you have any questions or concerns about the correct replacement, don't hesitate to contact us before ordering to ensure proper sizing. More than likely, we'll ask you to send a picture of the label located on the sleeper frame or the mounting bracket to mounting bracket measurement.
