Crafted from solid eucalyptus hardwood and pine wood harvested from renewable plantation forests. Designed for use without a box-spring. Back is semi-finished. You can sit against the headboard without concern thanks to the mortise and tenon joints and metal angle that firmly support the hardwood spindles. 100% Solid Wood - Made from a mix of eucalyptus hardwood and solid pine wood with eucalyptus veneer that provides a smooth and flawless surface. Finished with a non-toxic low-VOC paint made with solvents from 100% renewable sources. While the design looks lightweight, the mid-century spindle bed is amazingly sturdy thanks to its solid eucalyptus hardwood and solid pine wood construction. Details on the headboard posts are eye-catching without detracting from the organic simplicity and levity of the mid-century modern design. In the rear of the headboard, a metal angle provides a secure anchor for the hardwood spindles. Upgrade your bedroom today.
