Love this mattress in a bag. It’s got an innerspring that gives it a better form than mattresses without (like pure memory foam). It’s perfect if you’re using it on a daybed or trundle that doubles up as a sofa. I previously had a softplush memory foam for our daybed. And while it’s so plush, you feel like you’re going to sink in it and it’s not great for a sofa function. Now while this mattress is firm, there’s a bounce to it, still giving it that plush feel but keeping its form. The stitching and quality of this mattress is great too. I highly recommend it!
