Yes! You can place any memory foam, hybrid, or spring mattress on a top on a Zinus box spring.
We do have weight limits, but they are just suggestions. We’ve read in product reviews that our beds have withstood much greater weights. Here are our guidelines:
TWIN - TWIN XL = 350 lbs
FULL - CAL KING = 700 lbs
ADJUSTABLE BASES = 650 lbs
Please be advised that these weight limits exclude the mattress weight.
We strive to make assembly a breeze. Our box springs should come together in under 30 minutes. All tools if required come with your product.
