How to Make a Double Bed Frame Into a Queen Size

Metal Frames With Clamps

• 1

  Look for a clamp along the head and foot ends of the frame.

• 2

  Loosen the clamp to allow the left and right sides of the bed frame to slide apart at the head's end. Repeat for the end of the frame.

• 3

  Slide the left and right sides of the bed 6 inches apart, confirming that the left and right pieces of the frame still overlap by at least 4 inches.

• 4

  Place the clamp back over the overlapped pieces of the metal frame and tighten it until it will not move from side to side.

• 5

  Cut a sheet of 1/2-inch plywood 60 inches wide and 80 inches long. Lay the plywood in the frame, if the frame is made of angle-iron with the vertical sides of the frame pointing toward the ceiling.

• 6

  Drill 1/4-inch-diameter pilot holes through the plywood and the frame every two inches, one inch from the outside edge of the frame. Begin at the right corner of the foot of the bed, up the right side to the head of the bed, across to the left side and back to the foot of the bed.

• 7

  Place a fender washer on each 1/4-inch thread, 3/4-inch-long Allen-head socket screw. Slip the socket screws into each pilot hole in the bed frame. Add a second fender washer and cap each socket screw with an acorn nut.

• 8

  Hold each acorn nut with a socket wrench while you tighten each socket screw with an Allen wrench to secure the plywood to the bed frame.

Slot-and-Pin Construction

• 9

  Locate the pins and slots in the rails at the head and foot of the bed frame.

• 10

  Locate the pins and slots holding the left and right sides of the bed frame together. Push the left and right sides of the frame together to move the pins to the holes at the ends of the slots. Pull the left and right sides of the bed frame apart.

• 11

  Find the second set of holes in the frame. Put the pins back through the holes and pull the bed frame until the pins go to the ends of the slots.

• 12

  Continue with steps 5 through 8 of the procedure for a metal bed frame with clamps.

Wooden Bed Frames

• 13

  Center the short end of a sheet of 1/2-by-60-by-80-inch plywood on top of and even with the head of the bed frame, overlapping the foot of the bed.

• 14

  Mark the width of the bed frame at the head of the bed on the sides and top of the plywood. Snap a chalk line across the 60-inch end of the plywood between the marks on the left and right sides.

• 15

  Drill 1/8-inch-diameter pilot holes every two inches, through the plywood and into the frame. Switch to a countersink bit. Place the tip of the bit in the pilot holes and drill down at a 90-degree angle about 1/4-inch to countersink the holes.

• 16

  Mark the width of the bed frame at the foot of the bed on the sides and top of the plywood. Snap a chalk line across the 60-inch end of the plywood between the marks on the left and right sides.

• 17

  Drill and countersink holes every two inches at the foot of the bed. Secure the plywood to the bed using 1/4-inch diameter, 1-inch-long wood screws.
