LETTO

LETTO | Mattress Foundation
Regular price $275

A mattress is only as good as what lies beneath it. The LETTO Foundation gives your mattress the steady, even support it needs to settle properly and hold its shape, night after night, for years to come.

Choose the height that suits your bed. The 2" bunkie board sits discreetly on a platform bed or slatted frame, adding firm, flat support without raising the bed. The 3" and 5" foundations keep a low, modern profile, while the 7" foundation lifts the mattress to a classic height, making it easier to get into bed, and to make it each morning.

Every…

Size: Twin
Foundation Depth: 2" Bunkie Board

Available by appointment at our Portland, San Francisco and Los Angeles showrooms. Delivered to the showroom, not shipped to your home.
