Hi everyone, I´m trying to build an inexpensive, minimal platform frame for a queen size mattress. The idea is to use two 3/4" sheets of walnut veneer ply, cut as shown (see attached), glue and screw laminate, and add steel hairpin legs. My question, based on the attached drawing, will 1-1/2"...

When I was growing up in the early 50's my dad made a platform and put a twin mattress covered in upholstery cloth- we kept it in the dan, and he called it a heike- phonetically, a high-key. Anyone know where he got the plans or the name?
