I have this by the cooker for my essential cooking ingredients. It's flexible - adjust tiers as you want (see seller's pictures for examples), and it revolves so everything's handy. Stores a lot but compactly, footprint's just under 10inches/25cm. It's a bit like the TARDIS - capacity is more than it looks (doesn't travel in space or time!). Mine usually has about 16-20 items including bottles, jars and condiment mills. It's unwise to put tall and/or heavy bottles on the upper tiers, and neither the base nor upper tiers take very wide objects, but I've not found that a problem.
