I bought a lovely sofa bed from Made.com last summer, but its cushions are already seeing signs of sagging! I've recently placed support boards under the cushions, but am thinking of buying some high-density foam to place between the boards and the cushions for extra support. Quite disappointed as I live alone so mainly just me using it. It's clearly not up to family life.
Anyway, has anyone does this before? Did it work? TIA
