The column is absolutely fine. Easy to set up, stable, visually beautiful, about 80 cm high. The price is also ok. I was approached the square. Three sides scratch surface, a page "fur" with three holes with toy on an elastic band, even with noise (soft cheeping - like a fly on the wall - but not so loud that it would interfere with the opener when played with it). Our Stubentiger take the column, however, still not quite how we thought that and still go rather to the round, slightly lower the previous column. But perhaps that will come. I let the also not be included in my review because of the preferences of our Fellnasen can yes the pillar nothing :-)
