Use a bucket of ice-cream: cut the bottom of the bucket, leaving about an inch after the curve-will be used as seat. Use the other part of the bucket: let the part that the lid closes the bucket intact, facing down. Making the chair: let the highest part in the desired width - will be used as the backrest. Making the bottom seat: Cut and adjust where you will place the bottom seat, then place the first part you cut first. Use hot glue to make a layer of plastic that will restore the missing plastic around the bucket. Finally, use more hot glue around the seat to make sure there is no little holes around the seat before the glue is dry. Do not leave sharp ends on the backrest, cut at an angle to be safe for children. Always provide more then one chair for children.
