I am not a carpenter and this was my first attempt....you may want to put some slots in the solid wood panel under your bed. This will reduce the chances of your mattress going mouldy. Or just air your mattress outside occasional. I work in a bed shop and mouldy mattresses can happen quite quickly with moisture and heat.
