So how much weight can an Urban Shelf really hold? The question seems simple - but just like many of life's mysteries, it really depends on location and positioning. Some beds have no box spring, just a wooden or metal slat frame - which increases strength. When the base of the Urban Shelf is well supported at the bottom hinge, it benefits the weight capacity the most. Some mattresses are extremely soft on the edges. When coupled with a box spring that's ultra plush and has large rounded edges, the load capacity of Urban Shelf decreases.
Increase the strength of your Urban Shelf: Make sure that the mattress is lined up vertically with the box spring, or push in the mattress slightly. Keep the base of the Urban Shelf pushed all the way into the bed, this keeps everything tight and minimizes flexing under load. The same principles can be applied if you are using Urban Shelf on a couch.

Does your shelf bounce too much when you move around the bed? There is an easy solution - slide your Urban Shelf as close as possible to the headboard. Even the most acrobatic of couples will have a hard time making their Urban Shelf bounce when placed near the headboard. Sliding Urban Shelf closer to the headboard also makes it a tad easier to get in and out of bed.
