I aim to place, unsecured, (though blocked from movement on 3 sides) a piece of sheet/engineered wood on top of the side rails of a single bed frame. The siderails are 2 cm wide and will be acting as if beams supporting a subfloor. The horizontal space between the siderails is approx 92cm and the length is approx 191cm.
My understanding is I will be outwidth the max recommended spar/beam distance for a subfloor where I have seen a rough max of 60cm for a sheet of mdf at 22mm thick.
Can anyone recommend the best type of engineered wood for this please? IE • particle board/chipboard • mdf • plywood (softwood) • plywood (hardwood)
And possibly a thickness though I guess the thickest would be best?
Looks not important, I just want the type of engineered wood that is least likely to warp. Thanks G
