PP and ABS rather than wood make this rotating shelf light at 11 lbs and translucent enough to read the shape of what is stored behind the panels. It folds flat when not needed - unusual for a spinning bookcase - and the swivel base turns a full circle so the far side comes round with a push. Each of the three tiers holds 22 lbs. The unit measures 14.5 x 14 x 42.5 in, tall and narrow for a bedside or a study corner. Assembly is required; one bookshelf and an instruction sheet ship together.
