I'm interested in looking at some plans for a Tatami style platform bed frame. Hoping someone has some or can point me in the right direction. I've already found some offered on the internet but they seem to make compromises to accommodate woodworkers who have only a few basic tools. I'm also interested on opinions about building up the castles as opposed to using solid 4x4s. I see some commercial examples that are built-up but the mismatched grain is noticeable.
