Stability is key. Make sure your construction is properly positioned and horizontaly leveled. If necessary anchor to a wall to prevent the furniture from falling. When no walls are available, make sure to add enough weight to the base for better stability. Use the holes the closest to the edge of your construction when using feet. Good tools do make a difference, but what tools do you need? Depending on the type of material the panels are made of, you will need to use a hammer and/or a crowbar. Use a soft hammer and a small plastic crowbar for assembling and disassembling, but remember: always treat the materials gently for long lasting use and pleasure!
Build from the ground up and build from left to right. Always build upon another cube. After finishing the first row of modules, use either the adjustable feet or plinths to level out the construction.
Use one back panel minimum, per row and per column. Back panels are what makes your furniture stable
