Kingsdown Twin Xl High Profile Foundation
SKU: 50805551
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.

What is the benefit of a high-profile mattress foundation?
A high-profile foundation, like this 9-inch model, is the traditional choice for those looking to add significant height to their sleep set. This is particularly beneficial if you prefer a taller bed that is easier to get in and out of, or if you want to achieve a classic, commanding aesthetic in your bedroom. Additionally, the extra height can provide a more comfortable seating level when you're dressing or relaxing on the edge of the bed.
How should I maintain and clean an upholstered mattress foundation?
Based on our furniture care guidelines, we recommend regular vacuuming with an upholstery attachment to remove dust and allergens from the fabric surface. For minor spills or spots on the solid black upholstery, you should blot the area immediately with a clean, soft cloth and a solution of mild soap and warm water. Avoid using harsh chemicals or saturating the fabric, as this can damage the upholstery and the structural wood underneath.
Can I use this foundation with a memory foam or hybrid mattress?
Yes, this foundation is an ideal partner for memory foam and hybrid mattresses. Based on our expertise, these heavier, more flexible mattress types require a completely flat and rigid support system to perform as designed. The reinforced slat construction of this model provides the necessary "no-flex" support that protects the mattress core and ensures your warranty requirements for a proper support system are met.
Why is kiln-dried Canadian Spruce used in this foundation's construction?
The use of sustainably sourced Canadian Spruce ensures exceptional durability and strength. By kiln-drying and heat-treating the lumber, we remove excess moisture that can lead to warping, splitting, or squeaking over time. This advanced preparation process results in a stable, high-performance frame that maintains its structural integrity much longer than standard untreated wood bases.
How does the slat design of this foundation improve mattress support?
To provide a sturdier and more reliable base, the wooden slats in this foundation are cut a full inch wider than the industry standard and placed closer together. This dense slat configuration creates a more uniform support surface, which is critical for preventing the sagging or "sinking" that can occur with modern mattresses. By minimizing the gaps between slats, the foundation helps extend the lifespan of your mattress and ensures consistent comfort across the entire surface.
Is a Twin XL foundation suitable for a college dorm or a small apartment?
Absolutely. The Twin XL size (80"L x 39"W) is the standard for most college dormitories and is an excellent choice for studio apartments or guest rooms where space is at a premium. Because this foundation is meticulously hand-assembled with durable spruce and features an upholstered finish, it is built to withstand the rigors of frequent moves and the high-traffic lifestyle of a student or urban dweller.

A bit lumpy
This review was collected as part of a promotion
While the idea for an ajustable height pillow was a good one. The small “ cubes” of material were a bit lumpy and bumpy to sleep on. I did get “used to it”. But not ideal

Disappointing, Noisy Product
Unfortunately, the product is a disappointment. The Sealy StableSupport Foundation began squeaking with any movement on the brand-new Sealy mattress. Prior to this purchase, we had a generic foundation that was virtually noiseless for the nearly 10 years that we used it. After completing the Sealy warranty claim process, we received a replacement Sealy StableSupport Foundation. This replacement squeaks and creaks as much, if not more than the initial one. We really regret that we spent hundreds of dollars the Sealy StableSupport Foundation instead of keeping our former generic foundation that was about a quarter of the price and a better product.

Very Good Pillow With Fixable Issues
This review was collected as part of a promotion
Overall, the pillow is very comfortable and the cooling gel feels pleasant in the winter. It may be a little less firm than other foam pillows I have tried, but that is not a deal killer. Also, there was a strong foam smell when I first got the pillow which I remedied by taking it out of the hypoallergenic cover and airing it for a week. Overall, this is a very good pillow, which I would recommend.
