Perhaps I got the requirements wrong, but I thought you said the material needed to be:
Size = 4x8
Prefer 1” thickness but settle for ?”
Wood core is necessary due to Murphy bed HWI would really like it to come primed
The wood core and hardware attachment requirement rules out MDF or HDF IMO. ?I still think MDO is your best bet here. ?Combi or MDF skinned Plywood is susceptible to edge damage during handling since the MDF skin is thin and easily bruised and dented along the edges - been there, done that. ?So why risk it with Combi when MDO provides a paint-ready surface??

David,
Thanks for combo-core fdbk. I used MDO for my shop door with good results. Just not sure if I want to use it for a cabinet project if I have another option.
I assume you would have similar view of MDF/HDF skinned product. I am not sure if it is easier to dent MDF/HDF vs let’s say popular or birch plywood. Moisture should not be a major concern in bed room.
?Imran, I don’t like CombiCore because it has MDF layers which tend to dent when struck and are susceptible to moisture turning to oatmeal when wet. ?I use it only when doing custom veneer layups.
Have you considered Medium Density Overlay (MDO)? ?This has all wood layers like plywood but is sanded smooth and covered with special paper on both sides as part of the laminate. ?It’s smooth like MDF and doesn’t need sanding. ? I love the stuff for paint-grade projects because it takes screws and glue like plywood, but is also paint ready like MDF. ?
