How to Build Benches With Composite Lumber

The easilest composite lumber to make furniture or benches out of is MDF, because it is sturdy and easy to work with. Benches are easy to make; all you need is some composite lumber, a drill and screws to get the project going.

Items Needed

• Drill


• 1 Plank MDF, 12x40 inches


• 5/8 inch Screw


• 2 Planks MDF, 10x35 inches


• 2 Planks MDF, 10x17 inches


• Sandpaper


• Wood Stain

1. Put the two 10x 17 MDFplanks 30 inches apart on a surface. These will be the legs for the bench.


2. Put one 10X35 MDF plank in between the legs. This should create a right angle corner. Add a second plank 5 inches higher than the other one.


3. Using a drill, drill four holes spaced evenly apart on the outside of each bench leg. Use the 5/8 screw to secure it.


4. Move the bench upright. Put the 35 inch plank next to the legs at the top and other 35 inch plank roughly 5 inches off the ground (this will be the bench’s storage shelf).


5. Add the middle plank of 12x40 MDF for the seating. Make sure it hangs an inch over the sides. Secure this plank with the screw by drilling into the plank. When done, sit on the bench to test it and make sure it is secure for people to sit on.


6. Sand the bench with sandpaper and clean any dust off with a rag. Stain the composite lumber with a wood stain if desired. When painting the stain apply two times because the wood sucks in a lot of stain the first time.
