The SmartBase® checks off a lot of boxes on a bed frame wish list. Excellent mattress support without a box spring? Check. An abundance of under-bed storage space? Check. Assembly that's no sweat? Check! Frankly, we're not surprised that so many happy customers have traded in their two-piece box spring and bed frame sets for this reinforced steel base. It's designed with a metal platform that you can rest your memory foam, latex, or spring mattress directly on top of for extended mattress life. It's also engineered with multiple support legs for maximum stability and squeak-free use. Plus, those legs have plastic caps at the ends to protect your floors from unnecessary scratches. With swift assembly that only requires your own two hands. This extraordinary foundation is what we call a win-win.
