The next generation bed frame - The smart bed base mattress foundation by Zinus. The smart bed base eliminates the need for a box spring as your memory foam, spring or latex mattress should be placed directly on the smartbase. Uniquely designed for optimum support and durability the strong steel mattress support has multiple points of contact with the floor for stability and prevents mattress sagging, increasing mattress life. The smartbase bed frame is 35 cms high with 33 cms of clearance under the frame for valuable under-bed storage space. With plastic caps to protect your floors and an innovative folding design to allow for easy storage, the smart bed base is well designed for ease of use.
