Kingsdown Twin Xl High Profile Foundation
SKU: 50805551
Kingsdown foundations are meticulously hand assembled using sustainably sourced Canadian Spruce, which is exceptionally durable.

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.

Be aware
We purchased this bed in a split king in November. Overall, we're pleased with the product. It's comfortable, I've enjoyed the heating feature during this winter (haven't really used the cooling feature yet). My husband's sleep apnea has improved, which was the main reason for purchasing. There are a lot of "cool" features, but we don't use all of them for various reasons. One we haven't used is the surround sound speakers. Firstly, our bedroom TV doesn't have Bluetooth, and secondly, I don't need surround sound when I'm trying to sleep. We discovered this weekend though, that ANYONE can connect to the Bluetooth. Since we didn't have a device connected to our bases, apparently our neighbor found it in his list of devices and connected to it. Waking up in the middle of the night to a disembodied voice saying, "Bluetooth connected" followed by gunshots from your husband's side of the bed is not relaxing. There is no way currently for us to disconnect our bed from the neighbor's device without going over there and informing him (which we don't want to do for several reasons). We do not live in an apartment or townhouse. We are in an older, single family neighborhood and the house next door is at least 30ft away. They are currently sending us a new sound bar that will at least bump them off when we unplug our bed allowing us time to connect another device (don't know what yet), but it will not keep them from being able to connect again in the future if our device gets disconnected for some reason. This is a serious design flaw that needs to be fixed. Manual Bluetooth pairing should be required. If you decide to purchase this bed, make sure to connect a Bluetooth device to the bed whether you want to use the surround sound or not. For the money spent, we should not have to keep our bed unplugged to avoid being awoken by our neighbor's late night entertainment, making all those cool features useless.
