Space has always been a premium in my office/gameroom. With the limited shelves already full to capacity, I started stacking games on a nice window seat between the two cabinets (cross-stacked as necessary to prevent dishing!). I've looked at hard storage options and they either had too small of compartments or were too expensive or large (like IKEA shelving) for my needs.
With the stealth of the NSA, Google and Alexa seemed to share my findings to the web and suddenly Amazon recommended me these shelves. Assembled from plastic, metal tubing, and a plastic-like fabric, these shelves assembled like Tinkertoys, but were durable and strong (13.5lb load-bearing for each cube, 100lb load-bearing for overall items). Each compartment was over 13x12" as well, large enough for most common box sizes. At $21 a set, I ordered two to better organize my window seat storage.
Though designed to be set up in a 3-2-1 arrangement, other buyers reported you could also build them as a 3x2 tower (a 2x3 shorter layout is also possible). This is exactly what I would need to fit the space. Assembly was quick and easy. As I built them with less of a base than recommended, I scavenged the leftover bits to connect the two units together along the two shelf tops, reinforcing both shelves.
I'm quite pleased with how it all turned out and now when I need to get a game, I don't have to play Tower of Hanoi to extract the one on the bottom.
If organization is your problem and you cannot find a good solution, you might check out these units as well.
