I ordered this twin mattress for my new daybed and am so happy with the comfort level. I will say that the “plush” feeling is a little bit more firm than I initially thought it would be but the overall feeling has been really great. I’ve never owned a serta before so was hesitant to purchase but am very satisfied with this one. In case you’re wondering the daybed is also from wayfair and is called the “mid century daybed” )
