I have built seven of the Woodsmith version. I like the fact that it can become a youth chair as child growes. Hardware items were purchased from Rockler. Grand daughter who got the first one will be 18 in March, and we still use that chair when younger grand children come over. I have the original issue in my collection, so I still have the plans. The only problem with oak is you need to use a lot of pore filler on tray to make it smooth so clean up is easy. By using conformat screws for assembly, it can be taken apart and stored flat for future grand kids.
