FAQ:

Q: What is the best sofa bed mattress?

A: The 6-inch Ultima Memory Foam from Zinus ranks as our ‘Best Overall’ pick on our list of the top sofa bed mattresses thanks to its appealing attributes while still retaining a competitive price point.

Q: Can a sofa bed mattress be used as a floor mattress?

A: The sofa bed mattress also includes a multifunctional design, allowing it for use as a replacement sofa bed or floor mattress. Get the Milliard replacement mattress here. Milliard 4.5-Inch Memory Foam Replacement Mattress for Queen Size Sleeper Sofa and Couch Beds (Sofa…

Q: What is a memory foam sofa bed mattress?

A: Very few mattresses are made entirely of memory foam; most memory-foam sofa bed mattresses come with a top layer of memory foam on a supportive base layer of denser foam, such as polyfoam. When multiple layers are used, they are laminated together, keeping the mattress in one solid piece rather than separate layers that slide against each other.

Q: Is a firmer mattress better for the back?

A: In general, a firmer mattress keeps the body better aligned, and choosing a firmer mattress is good for the back. Foam mattresses use indentation force deflection (IFD) as an indication of how firm the foam feels and how much movement there is when weight is added. A higher IFD indicates a firmer foam, which usually ranges from 40 to 60.
