We purchased this to add to the thin mattress on our sleeper sofa when our family visited.  The foam was very thick after it was unrolled and expanded.  The fitted mattress pad that was included also provided extra cushioning.  It exheeded our expectations, and our guests were very comfortable with this extra padding for our sleeper sofa.  It did need to be removed from the bed before closing up the sleeper sofa.  We just rolled up the foam cushion and stored it in our closet.  Very pleased with this product!
