As of 2015, some good wooden bed frame designs include a wooden platform bed and a king-size bed frame. Both of these plans are available for free on Shanty-2-Chic.com.
The bed frame design for the wooden platform bed includes the plans for a full-size bed, but states that adjustments to measurements can change the bed size. These plans include a photograph for each step of the project along with written instructions.
A king-size bed frame plan includes more than 40 photographs of the steps required to complete the project and includes pictures of the types of tools needed. There is a link available to download and print the plans without the photographs.
