Trestle is Now Available. 

 

I tend to move frequently. I haven't had a traditional bed frame since I left my parents house before college, years ago. The rickety metal rails that came with my most recent mattress looked like something out of a Soviet prison; anything would be better. In designing this bed, the only constraints I put upon myself were that I should be able to store shoes and boots beneath it, and that it be made using simple CNC technology and 3/4" plywood.

In approaching this from a human-centered perspective, it was very important that the frame disassemble and transport easily. It needed to fit in my modestly sized car and be handled easily by just one person.

I settled on a hybrid platform/skeleton structure which relies on the lateral strength inherent in plywood. By turning the ribs on their sides, the bed is remarkably stiff. The small platforms bordering the central structure give the illusion that the mattress is sitting on a nice smooth sheet of wood.

 
 

The photos here show a queen size bed, though the CNC files will be available for 3 sizes - twin, full and queen size mattresses. The exact appearance of each will vary a little, but they'll all function the same. 

The release files for Trestle 2.0 will be made available in January 2016, and will include instructions for fabrication, as well as tips for working with plywood in this manner. Stay tuned for updates, and sign up for emails on an exact release date. 

 

development

This project was initially developed using rhino, but subsequent iterations have been made in Solidworks. Another added bonus of pursing this project is learning, and then becoming addicted to using the Shopbot at my local makerspace. My apartment will soon be covered entirely in plywood. 

This is where things got real. The baltic birch I used varied +- .2" from piece to piece, so my trusty orbital sander quickly became the MVP of this project. 

These photos are from my first iteration of the project. The original goal was to design a full-size bed frame using only one sheet of 4x8 plywood. This version evolved into the one you see above.
