Mattress (b/c we sleep on a futon bed and our backs hurt) Its only my back that hurt and it hurt because I carry heavy things on my back in my backpack. Now that I don't, the futon bed is sufficient.

Bookshelf (b/c we have non and I'm tired of having library books scattered everywhere)

Freezer for OAMC

Laptops for mobility, lack of space, usage of power.

Touring bikes and related gear (tents, sleeping bags, etc).
