All furniture comes with a ball end allen wrench for assembly, which works well! However, if you have a lot of furniture to put together, we highly recommend this 8 in 1 ratcheting screwdriver. It comes with the bit you need to assemble all of our furniture, in addition to 8 others. Use it for our furniture, and then keep it for projects around the house.
Use the extender to reach into tight spaces or without the extender for when you don’t have much room to work with.
