All of the frames do not require tools and come with clear instructions in the box - and you should expect assembly to take around 10-15 minutes. The directions for assembly are below:
You'll start by assembling the legs. Snap the leg bases and leg extensions together. Then slide the plastic inserts on top of the leg extensions. Next, you will build the frame and attach the assembled legs to the side rails, end rails, and support beam. Make sure to align the notches on the legs with the rails and push them all the way in. Once they are secure, slide the end rails onto the support beam, then slide the side rails onto the end rails. When you place the end caps over the ends of the side rails, your bed frame is complete!
