Three-Quarter Sofa Bed Mattresses
Hard to find but easy to upgrade. Our 3/4 Size (Three-Quarter) replacement mattresses are designed specifically for vintage and custom sofa beds with a 48-inch width.
If a standard Full is too wide and a Twin is too narrow, you likely own a ‘Super Single’ or antique sleeper mechanism. We offer premium options cut to these exact dimensions (typically 48″ x 72″), ensuring a perfect fold without jamming your classic furniture.

Customer Reviews
"The mattress came quickly, was very affordable for a quality memory foam with organic cotton shell, and is incredibly comfortable. I have two other sleeper sofas and look forward to upgrading their mattresses in the coming year. USA-made is always my first choice."
-James F.
"Ordered a replacement mattress for our hide-a-bed. Our first guest, my particular sister, couldn't rave enough on how comfortable it is!!! AND customer service DID help it arrive in time for her to use it. The sheets are super soft and added to the overall experience."

Common Questions About Three-Quarter Sofa Mattresses
Q: What is a 3/4 sofa bed size?
A 3/4 size (also known as a “Super Single” or “Three Quarter”) typically measures 48 inches wide by 72 inches long. This size was very common in older sofa beds from the 1970s-90s and in custom European loveseats.
Q: Will a Full size mattress fit my 48-inch mechanism?
No. A standard Full is 52-54 inches wide. Attempting to force a Full mattress into a 48-inch frame will cause the mechanism to jam and may damage the metal bars. You must use a true 48-inch replacement.
Q: Do you sell sheets for this size?
Yes. Because standard sheets won’t fit, we offer specialized 3/4 Size Sofa Bed Sheets that are sewn to fit the 48×72 inch dimensions perfectly.
