With its reliable steel structure, you can rest assured that your mattress will be sitting pretty. With different thicknesses to choose from, you can pick the one you need to customize the height of the bed.

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.
