IKEA hack - use a full-sized Malm bed frame and insert a Sultan Alsarp mattress base inside (it has the built-in lifing mechanism as shown in the pic) - now you can put the mattress on top of the frame/slats and lift it up easily to store things under the bed. AMAZING! I was planning on getting a full-sized Malm bed this spring so now I'm going to do this - BONUS STORAGE. love it!! :)
