Thank you for contacting us. Hope you are doing well. The Viscountess Storage Plush Velvet Bed - Black does not include mattress. However, you can add a mattress separately. Please check our mattress section to choose from a variety of mattresses. The collection includes Orthopedic, sprung, memory foam and backcare mattresses. I would recommend you have a look at the Evolution mattress, you can search it by using the keyword in search box on our website.
Feel free to contact us for further queries. Thank you, stay safe!
