Our Avocado Foundation with Legs functions as a sturdy, standalone bed frame no box spring or additional frame required. Built with a clean, modern design and tool-free assembly, it offers lasting support and maximized airflow. Our standard foundation features four legs and supports up to 600 pounds. For more robust needs, our new Heavy Duty Foundation with Legs is engineered to support up to 2,000 pounds, with up to twelve legs and four crossbars (two in each direction) for extra reinforcement. Both versions are just as easy to set up and are 7.25″ tall. Choose from dark brown 6.25″ or light brown 7″ solid wood legs. Compatible with any mattress.
