Like most other reviews, we found this assembly process to be very time consuming, but I could look passed that if the product were more secure. It states that there is 290 lb capacity, but I have concerns that this unit is not stable enough for our 55 lb dog. The base of the table is nothing more than a slightly thicker than normal particle board and the same material is placed on the back. If my dog is able to get a grip on any small piece of this, he'll chew it to shreds. Also, the entire table is built with cam bolts that can easily loosen over time. A majority of these bolts are inside the crate, so I'm also concerned that my dog is going to eat more than one of these. 
I think my dog could very easily wear this table down over time just by flopping around while he sleeps. I definitely wouldn't recommend this to anyone with a dog larger than 40 lbs. 

My husband joked that making it hard to assemble was by design so that buyers wouldn't want to take it apart to return it.
