Kingsdown Twin XL High Profile Foundation

Unlike a traditional box spring that uses flexible wire coils, this solid wood foundation provides a completely flat, non-yielding surface. This rigid support is essential for modern memory foam and hybrid mattresses, as it ensures they stay perfectly level to provide correct spinal alignment and prevents the internal mattress materials from shifting or warping.

A 9-inch high-profile foundation provides a traditional bed height, making it easier to get in and out of bed compared to lower-profile options. This height is ideal for standard bed frames and is a popular choice for larger master bedrooms where a taller bed profile creates a more substantial, elevated aesthetic.

No, this foundation is meticulously hand-assembled by craftsmen before it reaches your home. It arrives fully built and ready for immediate use, allowing you to complete your bedroom setup without the need for tools or the hassle of complex instructions.

This foundation is crafted from sustainably sourced Canadian Spruce that has been both heat-treated and kiln-dried. The kiln-drying process is a critical quality step that removes deep-seated moisture from the wood, significantly reducing the risk of warping, shrinking, or cracking over time. This expertise in material preparation ensures the frame remains structurally sound and silent throughout its lifespan.

To provide a sturdier base than standard models, the wooden slats in this foundation are cut a full inch wider and placed more closely together. This increased surface area offers superior reinforcement for your mattress, helping to prevent the sagging and dipping that can occur with less robust support systems, thereby extending the life of your mattress.

Yes, two Twin XL foundations are the standard requirement for a King or Split King mattress setup. At 80 inches long, they provide the necessary extra length for "XL" mattresses. Placing two side-by-side creates a stable, 78-inch wide base that is much easier to navigate through narrow stairwells or apartment doorways than a single-piece king foundation.
