Made to stand up to over 4000 pounds, the SmartBase® Super Heavy Duty Mattress Foundation is built to last a lifetime (or maybe even a few lifetimes). It’s engineered with a reinforced steel platform that can support your mattress without a box spring, so this single, ultra-durable piece of furniture is all you need to rest comfortably. At 14 inches tall, this SmartBase boasts over a foot of under bed space perfect for tucking away extra storage boxes, luggage or linens. Equipped with features like recessed legs to keep you from stubbing your toes and plastic leg caps to protect your floors and provide noise-free use, this foundation is not only solid as a rock, but incredibly practical too. A unique folding design makes both assembly and storage a breeze, and its 5-year warranty adds more value that’ll make sleeping on this modern marvel all the more peaceful. 


  • THE ONLY BED FRAME YOU’LL EVER NEED - With the ability to support more than 8 times the weight of a traditional platform bed, the Super Heavy Duty SmartBase® is built to stand the test of time and ideal for cosleeping families and plus-sized individuals
  • NO BOX SPRING NEEDED - Platform is made with sturdy steel that replaces your box spring, allowing you to rest your latex, memory foam or spring mattress directly on top
  • UNDERBED STORAGE - Total of 12.5 inches of clearance space under the frame provides valuable storage room for extra odds and ends
  • QUICK, TOOL-FREE ASSEMBLY - Shipped in one compact box and requires no tools for assembly; twin and twin XL sizes support a maximum weight capacity of 2200 lbs, while all other sizes can support up to 4400 lbs
