Storage solutions for bedroom - just Lakeland?

[futurity]

I have a built in wardrobe which has just enough hanging space but there is a shelf on the top of it which I don't really use as well as I could do. I have been looking at the Lakeland website for clothes storage solutions but wondered if anyone knew of other places to get things like stacking box systems/under bed storage etc etc.

I got some zip-up canvas boxes from Ikea under my bed. Grey with yellow trim very smart. I'm not keen on plastic boxes as some of them get brittle and break if used often. Hope this helps
