This was my first time ordering from Wayfair, and I am very pleased.  I looked around quite a bit for an enclosed litter box, and this was by far the best price for the look that I wanted.  We were moving and needed a different litter box solution for our new space.  I have this in my study, and you can't tell that it is hiding a litter box, it looks great.  My cat is 12-13 lbs. and 8 years old.  She had never used an enclosed litter box before, but she got the hang of it right away.  It took me about 45 minutes to put it together by myself.  I just used the couch to help support the weight of the lid while I attached the hardware.  Every single piece of hardware is labeled very well.  This is a sturdy, attractive unit, very satisfied with my purchase.
