Kingsdown Twin Xl High Profile Foundation

Not available in your region

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.

We are very happy with the TEMPUR-Cloud® + Hybrid Mattress. My husband has cervical issues, and this mattress has made a big difference in his comfort and sleep. Thanks a ton

No more hip pain….and I don't feel him get out of bed!

This review was collected as part of a promotion

We added the TEMPUR-Adapt + Cooling Topper to our firm Purple mattress to help with my lower back & hip pain and my boyfriend’s sciatica, and it has been a total game-changer!! After a month, we are both waking up rested and without pain for the first time in years, and the motion isolation is so good I no longer wake up when he gets out of bed to pee a million times throughout the night. Added bonus…The cooling cover is perfect for our South Carolina climate + my perimenopause symptoms 🥵 …. highly recommend for anyone struggling with joint pain!

The TEMPUR® material adapts to the body while hybrid coils provide great support and alignment. My husband has cervical issues, and this has really improved his comfort. A big thank you from him!
