Hi Flora!
We appreciate the time taken to share your thoughts, as well as your order with us. We are happy to hear that you are enjoying your new sofa an that it is a good fit, but sorry that it is not yet perfect in terms of firmness. We'd be happy to share some info!
At the time your order was received, it was brand new from the factory and all cushions were at their absolute firmest. With time and love, your cushions can indeed be expected to reduce in firmness by up to 15%, providing a slightly more relaxed feel, making your sofa even more comfy for your lounging needs. :)
Thank you again for sharing, and feel free to reach out to our support team at support@apt2b.com should you need any assistance!
