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."
"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 Full Size Sofa Mattresses
Q: What are the exact dimensions of a Full sofa bed mattress?
A standard Full size sleeper mattress is typically 52″ to 54″ wide and 72″ long. This is slightly narrower and shorter than a regular bedroom Full mattress (which is usually 54″ x 75″) so that it can clear the metal folding frame.
Q: How do I know if I need a Full or a Queen?
The easiest way is to measure the width of your metal sleeper frame from inside bar to inside bar. If the measurement is between 52 and 54 inches, you need a Full. If it measures closer to 60 inches, you need a Queen.
Q: Will a thicker memory foam mattress still fold into my couch?
Yes! Our 4.5-inch replacement mattresses are specifically engineered with the correct density and flex-points to fold away smoothly without putting stress on your sofa’s mechanism. If your old mattress was between 4 and 5 inches thick, our Full size options will fit perfectly.
