Kingsdown foundations are meticulously hand assembled using sustainably sourced Canadian Spruce, which is exceptionally durable.

Q&A answers generated with AI assistance.
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.
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.
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.
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.
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.

Very Uncomfortable

While the pillow cooling feature is nice, it unfortunately hurt my neck for several days after using it. Disappointed they cannot be returned.

Perfect for us.

We have an old Tempurpedic mattress that we love. We were thinking it was about time to get a new one but we didn’t think we could get anything like the original and didn’t know which model to get. Updating felt like a risk. Then I saw the topper. It seemed like a low cost way to experience the current product. We purchased the topper and found it very comfortable. It was the perfect addition to our current Tempurpedic. The fit is great and the straps to hold it in place do a reasonable job. Having a better idea of how the current technology feels, we will probably refresh in the future. But, now with the topper, we don’t have a sense of urgency, nor do we feel a great need. It has proven to be a great addition for us as a retired couple.

Not impressed with the firmness

Was a little short on the sides, ordered Cal King which is what it is and the sides were short about 2-3 inches on each side.

Very smooth and cool to the touch every night I jump into bed. Even after many washes it keeps its comfort and coolness.

Very nice pillow. Definitely shaped to fit the head more naturally. Just a bit of a change for me, a bit of discomfort and I'm still getting used to it.
