Materials: EXPEDIT cube (no longer available, you may try the LACK side table with casters) I secured three large EXPEDIT cubes together as seen in picture. I then nailed them together. I placed a large piece of MDF on top along with foam and fabric and stapled in place. For the seating back I used a thinner plywood with a vey thin foam and fabric and stapled it all in place.
