Hi Linda,

Thanks for shopping with us. The Miami bed comes with slats, that are made out of solid wood, that support the mattress. If you have any other questions just let us know. Thanks.

Hello Linda, and thank you for your inquiry. This bed includes a hand made solid wood slat kit. The slats are made of solid Mahogany and are an integrated system that joins with the beds side rails and central support rails to hold the mattress up. No box spring is required. Hopefully this helps answer your question, and please let us know if you need any further assistance.

Thank you.
