Kingsdown Twin Xl High Profile Foundation
SKU: 50883478
Kingsdown foundations are meticulously hand assembled using sustainably sourced Canadian Spruce, which is exceptionally durable.

Each wooden slat is placed more closely together and cut a full inch wider than most manufacturers to provide a sturdier base.

Q&A answers generated with AI assistance.
Does this foundation require home assembly?
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.
Why is a solid foundation often preferred over a traditional box spring?
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.
What is the benefit of a "high profile" 9-inch foundation?
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.
How does the slat construction provide better support for a mattress?
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.
Why is kiln-dried Canadian Spruce used in this foundation’s frame?
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.
Can two of these foundations be used together for a split king bed?
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.

We bought a cheap hybrid mattress with thin top and added this topper on it which made it perfect for us.

It’s not just a solid chunk of rubber foam
This review was collected as part of a promotion
Unlike many other memory foam type pillows, this one is filled with foam shredding. The plus side outweighs the negative on this. For example, I was able to open up the zipper and adjust the size of the pillow by removing the right amount of shreddings. On the other hand, it is messy messy messy. Final result was worth it. I was able to take the pillow that was shipped and adjust it to my personal needs. You cannot do this with pillows that are a solid chunk. Bravo!

Great Bed Base BUT Missing One Basic and Essential Feature
This is a great bed base for those of us desiring only basic function without the extra frills of under-bed lighting and USB ports for phone charging, or the extra things to malfunction those frills add. However, and most unfortunately, and very disappointing, is the sad fact that one must spend the extra money for those "frills" just to get what should absolutely be a basic function not lumped in with the "extra frills" - favorite position memory settings. If the Ease base included this basic function, I would have easily given it five stars.
