This item is very poorly made.  The wood itself is the thinnest, and least sturdy form of particle board, and the sides attach the the crate via magnet.  Ours fell off repeatedly, and were only able to stay through the use of zip ties.  The cage itself is of a grade so light and poor quality that my 7 lb dachshund was able to push the bars apart and escape during the day.  That was fun to come home to as you can imagine.  Honestly, please save your money and purchase a different item, ours has lasted less than 2 months and we will never purchase something like this again.
