Step 6Slide in front beam and then back beam
iImage Information

Select two frame sheets and put them next together. We doubled up the outer frame sheets to make them a bit more sturdy. One of these sheets should be your nice clean sheets that you want to show. Next individually slide in the pieces of your front beam. For every half inch width of a beam slot, you will need around 4 sheets (i.e., for a 1.5 wide beam you will need around 12 sheets and for a 1.0" wide beam you will need around 8 sheets) When you get to your last one sometimes it's easier to slide it in-between two beam pieces. Slide on the third frame sheet spaced 5-6 from the the other two. Slide on the fourth frame sheet spaced 5-6 away from the third one. And then double up the fifth and sixth ones (the sixth one having the pretty side facing out) and slide these on near the end of the beam. Now slide in the pieces for the back beam. Now slide in the sheets for your back beam.
At this point your couch should be able to stand up on its own fairly well.
