Kingsdown Full High Profile Foundation

Most premium mattress warranties require a flat, firm surface with specific support requirements to prevent long-term damage. This Kingsdown foundation is hand-assembled with slats positioned more closely than standard models, specifically designed to exceed the support needs of high-end mattresses. This meticulous construction ensures your mattress remains level, helping to satisfy warranty conditions and prevent premature wear.

While a traditional box spring contains internal coils designed to "give," this foundation provides a solid, non-flexible support surface. Modern mattress technologies—particularly memory foam, latex, and hybrid models—require the rigid, stable base of a foundation like this to prevent structural sagging and ensure the mattress performs as intended for its full lifespan.

This foundation is engineered for exceptional durability using sustainably sourced Canadian Spruce. Unlike standard bases, this lumber is both heat-treated and kiln-dried, a process that removes moisture to prevent the wood from warping, cracking, or squeaking over time. Additionally, the slats are cut a full inch wider and placed closer together than the industry average, creating a significantly more robust platform for your mattress.

Yes, provided the wood is treated correctly. Because this foundation is built from kiln-dried Canadian Spruce, it is far more resistant to the moisture-related expansion and warping that can affect lower-quality wood in humid environments. The kiln-drying process stabilizes the timber, ensuring the frame remains quiet and structurally sound regardless of local humidity fluctuations.

No customer assembly is required for this item. This foundation is meticulously hand-assembled by craftsmen before it reaches your home, ensuring that every joint and slat is perfectly secured. It arrives as a single, solid unit ready to be placed directly onto your bed frame for immediate use.

This is a "high profile" foundation with a height of 9 inches. When paired with a standard mattress, it creates a traditional bed height that is often preferred for its classic aesthetic and the ergonomic ease it provides when sitting down on or standing up from the bed. For those with a very thick mattress or who prefer a modern, low-slung look, a low-profile foundation might be a more suitable alternative.
