To reduce the amount of cold air getting to the front bed area I used bubble foil insulation and using a framed-panel blocking off the under-bed storage from the front pass thru storage. I stapled the foil insulation underneath the entire wood bed platform and top surface area within the pass thru storage.
I also insulated behind the framed-wood panel (not shown), and acted as an added bed frame platform support as well.
