low , wide shelving units ?

Im looking for a something thats almost like a shelving extension or small unit about 19cm h 28cm w and the longer the better length with ideally two shelves.

This is close to what I wanted except its got no base and isnt high enough.

Its basically to use a discrete shelving I can fit next to my bed / wall to store things below out of sight ( not those kinda of things ! ) and more scenic things ontop like dioramas , plants etc etc

I would prefer wood if possible - just pines fine.

Any suggestions any one ?
