The Saatva 4.75" Low-Profile Foundation in Split King (comprising two individual Twin XL modules) is a premium, handcrafted structural support system meticulously engineered to replace traditional box springs. Designed specifically for high-profile luxury mattresses or individuals seeking a lower overall bed height, this low-profile foundation provides optimal rigid support, preventing premature mattress sagging while extending the lifespan of your sleep surface.
Constructed from eco-friendly, kiln-dried North American hardwoods, this foundation features a heavy-duty slatted architecture that ensures consistent weight distribution and superior breathability. The entire framework is encased in a stylish organic cotton blend cover, treated with proprietary Guardin® botanical antimicrobial protection to inhibit bacterial growth and maintain a hygienic bedroom environment.
The Split King configuration—delivered as two separate Twin XL foundations—makes maneuvering through narrow hallways, staircases, and tight doorways effortless compared to a single-piece King foundation. When placed side-by-side on a standard King bed frame, the modules create a seamlessly unified, ultra-sturdy 76" x 80" base that supports any standard King or Split King mattress perfectly.
