The DUX Bed interior frame is built from the highest quality slow growth Swedish pine, one of the strongest and most resilient pines in the world. Designed like a piece of furniture, The DUX Bed’s interior frame allows you to simply select the leg style, height, and color of your choice and fasten the leg to the frame by threading it into place. Additionally, should your bed height or style-needs change, you can simply adapt your bed by replacing the legs at any time. For some this may just be a stylistic consideration, but for others the ability to change to taller legs to help them get out of bed as they age can be of paramount importance.
