The perfect solution, but unfortunately the nearest 2 IKEAs are 100 + miles away. London or Nottingham. Not an option, & I cannot see any mention of mail order on their web site.
Agreed Tony. My shelves will be in one of the spare bedrooms. After seeing what happened to the cardboard boxes, I have now put everything on wood strips or pallet. This should keep the air circulating. If I do use chipboard, then I will put strips of wood underneath for support, but thinking it through, the strips would probably have to be fairly large seeing as chipboard has very little inherent strength to bending (sagging). The last time I bought any decent wood it cost an arm and a leg, so not looking forward to this exercise. Cheers GeoffH
