We like to think of a box spring as the backbone for your mattress. The best kind should be flat, level and built to keep your mattress in tiptop shape; and that’s just what the Smart BoxSpring® does! With its easily assembled, dependable steel structure, you can rest assured that your mattress will be sitting pretty. An included poly jacquard cover zips on to seamlessly blend with the rest of your bedroom, and with a variety of different thicknesses to choose from, you can pick the one you need to customize the height of the bed.
Steel interior frame with knitted polyester cover
Unlike a traditional box spring, the Smart box spring is made of solid steel that comes together in no time
Durable steel is used to construct the inside framework of this foundation; slats are spaced 6 - 7 inches apart
Weight Capacity: twin size supports a maximum weight capacity of 350 lbs, while all other sizes can support up to 700 lbs.
A 5 inch height is perfect for taller mattresses or for those who enjoy their bed lower to the floor
A 9 inch height is perfect for shorter mattresses or for those who enjoy their bed higher off the floor
All parts, tools and instructions are packed into one compact box that ships straight to your door
Box spring only, a bed frame or platform bed is required to support this foundation and is sold separately
At Zinus, we’re in the business of creating harmony, which is why we make some of the comfiest mattresses you can sleep on. Infused with natural ingredients like green tea, charcoal and olive oil and no harmful chemicals that are hard to pronounce (like phthalates), you’ll sleep with peace of mind! In addition to fitting fluffy mattresses into wonder-filled packages, you’ll also find stylish, comfy and easy-to-assemble bed frames, sofas and more.
