    Verified Purchase

    I found this to be a very firm mattress, and had to add a memory foam topper and feather bed, to make it comfortable.

  • Day bed mattress
    Verified Purchase

    With 4 grandkids as occasional visitors, I needed sleeping arrangements for all. This mattress fits a daybed frame which is slightly smaller than a traditional twin. I bought 3 to go with our daybed. Each grand has a mattress and the mattresses all store on or under the daybed. Very handy without taking up a lot of room.
