Hey Dan K, we are sorry to hear your mattress hasn't fully expanded! Our customer service team will get to your email and help you as soon as they can. In the meantime, if you'd like to contact Home Depot, go ahead and reach out to them directly. While you wait, there are a few things we recommend you can do to speed up the process. Sometimes the foam gets "stuck" and it needs help. Keeping it in a warm room can help with that. You can also walk or crawl along the top for a few minutes throughout the day, as that can help break up the air pockets in the foam. We hope this helps and we apologize for any inconvenience. Thank you! Lucid. Beds for the Whole Family.
