Sleep system with modular foundation controls

A sleep system comprising:

• a modular foundation configured to support a unitary mattress having a medial head split and a medial leg split, the modular foundation comprising a head section, a leg section, and a middle section between the head section and the leg section, each of the head section, the middle section, and the leg section removable and re-combinable to form the modular foundation, the head section comprising a first portion and a second portion, the first portion extending laterally along a first width of the head section and extending longitudinally along a first length of the head section and the second portion extending laterally along a second width of the head section separate from the first width and extending longitudinally along the first length of the head section, the leg section comprising a first portion and a second portion, the first portion extending laterally along a first width of the leg section and extending longitudinally along a first length of the leg section and the second portion extending laterally along a second width of the leg section separate from the first width of the leg section and extending longitudinally along the first length of the leg section;
• and
• a controller operatively coupled to the modular foundation, the controller configured to perform operations comprising:
• independently articulating one or more of the first portion of the head section, the second portion of the head section, the first portion of the leg section, and the second portion of the leg section.
