Although the Air Dream Mattress system is designed to fit most sleeper sofas, there are some sleeper sofas that the Air Dream Mattress will not fit in. If purchasing the complete Air Dream Mattress please measure the length, width, and height of your existing sleeper mattress before ordering and confirm your mattress measurements are the same as the Air Dream deflated measurements listed below. If your measurements are not the same as the Air Dream deflated measurements your sleeper sofa may not be able to accommodate the Air Dream Mattress and/or may damage the Air Dream Mattress.

Please note: We do not recommend the Air Dream as an every-day mattress or for rental properties - only for occasional guest use. Please call for shipping quotes to Alaska and Hawaii.

If you're unsure, please contact us before ordering to ensure proper sizing. 

The strongest sleeper mechanism made, the Classic 3500 Square sofa sleeper system includes engineered low-profile linkage along with body-support tubes and wires for enhanced support. It eliminates sagging and the two-ply ballistic decking material enhances durability and visual appeal. The Classic 3500 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 3500 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. The dual one-piece tubular legs also provide enhanced stability and strength, making this one of the highest quality products on the market.

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 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.

Available in the Following Widths:
