Building your own bed base for an average king-sized mattress rather than buying one in a shop saves you money. Bed bases, or frames, raise mattresses 15 to 20 cm (6 to 8 inches) off the ground so they are at a more comfortable level for people to get in and out of bed.
Cut two 198 cm (78 inch) pieces from the 5 by 10 cm (2 by 4 inch) boards with the circular saw for part of the frame.
Cut four 142 cm (57 inch) pieces from the 5 by 10 cm (2 by 4 inch) boards.
Cut the four 1.8 m (6 foot)10 cm by 10 cm (4 by 4 inch) pieces in half for the eight legs that support the frame.
Trim the sheet of plywood down to a 152 cm by 198 cm (60 by 78 inch) piece for the top of your frame.
Sand all rough edges of the cut pieces. Apply wood stain or paint and allow to dry.
Find a hard surface and place the two 198 cm (78 inch) pieces on edge parallel to each other, 152 cm (60 inches) apart. Complete a rectangle by laying the two 142 cm (57 inch) pieces between them. Drive three 6.2 cm (2 1/2 inch) screws through each end of the longer pieces into the shorter ones.
Add support beams inside the frame using the other two pieces of 5 by 10 cm (2 by 4 inch) board. Lay them on edge parallel to the shorter sides of the frame. Equally space them out inside the frame and attach them. Drive two 6.2 cm (2 1/2 inch) screws through the 198 cm (78 inch) sides into the ends of the two support beams.
Stand a 90 cm (3 foot) piece of 10 by 10 cm (4 by 4 inch) board on end against each inside corner of the frame for the legs. Drive 6.2 cm (2 1/2 inch) screws through the frame into them. Use two screws on both sides of the frame that each leg touches.
Sit another 90 cm (3 foot) piece of 10 by 10 cm (4 by 4 inch) board on end in the centre of each of the longer sides against the inside of the frame. Drive four 6.2 cm (2 1/2 inch) screws through the outside of the frame into them.
Use the remaining two 90 cm (3 foot) 10 by 10 cm (4 by 4 inch) boards pieces for the legs in the centre of the frame. Sit one 10 by 10 cm (4 by 4 inch) board on end against the centre of each support beam. Put them against the sides of the support beams closest to the outer frame. Drive four 6.2 cm (2 1/2 inch) screws through the side of each support beam into them.
Flip the completed portion of your frame over on the legs and put the piece of plywood over the frame so it lines up. Drive one 3.7 cm (1 1/2 inch) screw down through the plywood piece every 15 cm (6 inches) around the edges into the frame including the support beams.
Add extra strength to the eight legs by driving two 3.7 cm (1 1/2 inch) screws down through the plywood piece into each one. Your new frame is ready for a mattress.
Be cautious when using power tools.
