just putting it out there for people thinking of doing this - ive been warned by multiple sources against using a solid wood surface as a bed frame, it’s a big struggle with mold. So maybe add holes or some sort of break in the wood so your mattress has air flow underneath? or use specifically mold resistant paint?
i have also put a lot of thought into pull out/pull down/slide out murphy style or multiuse bed frames.
most people seem to prefer not to deal with the hassle of making up the bed everyday.
but there are also some who find the break in the mattress where the cushions for the couch meet to be uncomfortable.
so cons: mold prone as is, potentially uncomfy pros: space saving, simple build design
im curious if you stuck with this design and how it went?
