This Cattelan Italia Designer DNA Bookcase is a contemporary/modern piece of furniture that we loved having - we are no longer in our modern apartment so time to move it on! It is in really excellent condition, we only used it for books and so it's really like new. 

The bookcase is made of matte black steel and has a unique spiral shape with 13 shelves - reflecting a double helix in DNA. 
It is in one piece and requires no assembly. It is free-standing, so it's easy to move and position but do note that it is very heavy for stability, at least 25kg! It is 36 cm in diameter and 181 cm high. 

The bookcase is part of the DNA Studio Dainelli 2008 collection by Cattelan Italia, you can see more details including the spec sheets here --> https://www.cattelanitalia.com/en/products/531E3679-C228-4298-BE2F-AE80F993126D?c=24

Collection only, it is too big and heavy to go in standard postage services I'm afriad.
However I'm happy to work with the buyer if they wish to organise a courier at their cost.
Please let me know if you would like more info or photos!
