Hi Becs! Thank you for providing your feedback to us, we're sorry to hear the BRS900-C mattress was too firm for comfort. Since we make our mattresses with freshly poured foam, it can take a couple of weeks for the mattress to acclimate to its new home, and you to it. Adding a topper can be a simple and effective solution as well! While we understand returning may not be ideal, if you are within your return window with Home Depot, feel free to reach out to their team and they can guide you through the return process. We appreciate your candor and hope this leads to a swift resolution. Feel free to reach out if you have any other questions or concerns moving forward, we're here to help!
