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.
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.
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.
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.
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.
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.

Very Disappointed
This review was collected as part of a promotion
This was the most uncomfortable pillow I have ever used. Ended up donating the two that I purchased to charity. Hopefully for someone, they will be better than nothing at all.

Good but hard as a rock

This pillow will last for a century. I very pleased with the mild cooling effect. Glad I added that. The pillow will soften more and has softened a bit, but generally stay hard. My only wish is that the “neck hump” was a bit narrower since my neck is not as long as the hump is wide. Hopefully will continue to soften. It’s been a month. I know it was a great purchase and I’m confident I will continue to adapt.

Worst pillow I’ve ever had
This pillow is not what they say it is. It has an awful off gassing from the foam they use. Even with doing the measurements it did not fit me and it is extremely small. I used it for one hour and night it was so bad I had to get adjusted the next day. Oh also their is no returns on it so it’s not worth the risk and the money

My Head is in Love

This is my second Tempur-Pedic pillow. The last one I had for over 15 years and it was still in good shape, but starting to get a little smelly. These pillows have truly prevented the giant knots I used to get in my neck from sleeping wrong.

Neck pain
This review was collected as part of a promotion
The pillow sits up too high and was giving me neck pain while sleeping on it. It ended up just being a waste of money.
