Kingsdown Twin Xl High Profile Foundation
SKU: 50883478
Kingsdown foundations are meticulously hand assembled using sustainably sourced Canadian Spruce, which is exceptionally durable. Each piece of lumber is not only heat-treated, but kiln-dried, which improves the performance of the wood over time. 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.

Pros & Cons
The straps to hold on place are extremely stretchable and don't keep it in place. Every night I have to adjust it. It doesn't do anything as far as cooling. That was an added price that wasn't worth it. As far as the softness, it is definitely comfortable. Not sure it's wish it overall though.

Like sleeping on a rock

The quality of the mattress is nice, but it’s incredibly hard, with no give. We’ve slept on it a few times and are in the process of trying to exchange it for a High Point II

No more pain

My morning back pain is gone. Since moving to this mattress, my sleep shifted from painful to deeply restorative. I used to drag through the day; now I wake up alert and energetic every morning. Highly recommended for anyone suffering from back issues.

Failed product with very poor warranty
My mattress failed and offers no support. I bottom out and cannot sleep with any comfort. The company’s warranty is a fraud in my opinion. They refuse to inspect the mattress to make an honest decision. They ask for photos be sent to them and they deny the claim based on their own arbitrary interpretation. They send you a list of all the things that void the warranty and deny the claim even though none of those items apply to my mattress. It is a phony warranty that covers nothing in my opinion. And the company is miserable and biased to deal with. They have zero compassion and with no proof will flat out deny your claim. Also their product has deteriated in quality over the years as I have personal experience. Go to a mattress store and sit or lie on one of their new mattresses…any one of your choice and you will probably experience that you go to the bottom. I would strongly suggest you consider any other mattress brand and I believe you will be much happier in my opinion based on my personal experience. Stay away from this company to avoid discomfort and potential future aggravation. There are so many better products and better companies to choose from in my opinion. Buyer beware!
