I used two FROSTA stools and two BILLSTA table tops to make a nice set of sofa tables for the living room.
1. Take the legs off the stools.
2. Shorten the legs from one of the stools to make one of the tables lower.
3. Screw the legs on the table tops (the pre drilled holes will fit)
4. Put the stool seats on top of the tables as decoration or serving trays.
