This rack has just arrived as has a slightly shorter one, it measures 52 x 40 cm for the top three shelves and 50 x 51.5 cm for the bottom shelf. The overall height is 105 cm to the top of the poles and of course the shelves are adjustable.
The rack is in excellent order but there is no packaging although it can be dismantled for transportation.
I would prefer collection rather than shipping due to the lack of packing materials. The price reflects this.
