Created to support our best-selling EA Signature™ mattresses, our EA Signature™ foundations are crafted from Canadian spruce lumber that's responsibly harvested; for every tree removed to construct our foundations, a new tree is planted in its place. Available in multiple heights so you can position your sleep surface exactly where you want it. Designed and engineered to support our EA SignatureTM mattresses. Also supports our DREAM eazzzTM memory foam mattresses. Kiln-dried solid wood frame and supports constructed from responsibly harvested, durable Canadian spruce lumber. Taupe linen-like woven polyester fabric cover affixed. For delivery purposes, all king and California king beds use two side-by-side foundations. Queen split is also an option for queen beds. These sizes are sold online as pairs. Find our recommended mattress and foundation pairings for Ethan Allen beds here. For other beds, we recommend that the surface of your mattress be 24" to 30" above the floor. To calculate sleep surface height, add the distance between your bed base and your floor, the height of your foundation, and the height of your mattress.
