Buying a new headboard can be expensive. Luckily there is another way to renew your bed at a lower cost. Step 1: Buy a desk top/ plywood. You can find them in different sizes and colors in furniture stores. Step 2: Cut the board to the height you want your headboard to be. Step 3: Screw the new headboard directly onto the old one from behind so you can't see the screws. Option: For optimal comfort, install the board at an angle.
