Kingsdown Twin Xl High Profile Foundation

Not available in your region

SKU: 50805551

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.

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.
